Bottlenose Dolphin Facts Behavior, Senses, Diet

Bottlenose dolphins are known for the elongated shape of their upper and lower jaws or rostrum. They are the most common type of dolphin, found everywhere except the Arctic and Antarctic. The bottlenoses so-called nose is actually the blowhole on the top of its head. There are at least three species of bottlenose dolphins: the common bottlenose dolphin (Tursiops truncatus), the Burrunan dolphin (Tursiops australis), and the Indo-Pacific bottlenose dolphin (Tursiops aduncus). These playful mammals have the largest brain mass per body size of any animal except humans. They display high intelligence and emotional intelligence. Fast Facts: Bottlenose Dolphin Scientific Name: Tursiops sp.Distinguishing Features: Large gray dolphin characterized by its elongated upper and lower jawsAverage Size: 10 to 14 ft, 1100 lbsDiet: CarnivorousAverage Lifespan: 40 to 50 yearsHabitat: Worldwide in warm and temperate oceansConservation Status: Least Concern (Tursiops truncatus)Kingdom: AnimaliaPhylum: ChordataClass: MammaliaOrder: ArtiodactylaFamily: DelphinidaeFun Fact: After humans, the bottlenose dolphin has the highest level of encephalization, leading to high intelligence. Description On average, bottlenose dolphins reach a length of 10 to 14 ft and weigh around 1100 pounds. The dolphins skin is dark gray on its back and pale gray on its flanks. Visually, the species is distinguishable from other dolphins by its elongated rostrum. A dolphins flukes (tail) and dorsal fin consists of connective tissue, lacking muscle or bone. The pectoral fins contain bones and muscle and are analogous to human arms. Bottlenose dolphins living in colder, deeper waters tend to have more fat and blood than those living in shallow water. The dolphins streamlined body helps it swim very quickly — over 30 km/hr. Senses and Intelligence Dolphins have sharp eyesight, with horseshoe-shaped double-slit pupils and a tapetum lucidum to aid vision in dim light. The bottlenose has a poor sense of smell, since its blowhole only opens for breathing air. Dolphins seek food by emitting clicking sounds and mapping their environment using echolocation. They lack vocal cords, but communicate via body language and whistles. Bottlenose dolphins are extremely intelligent. While no dolphin language has been found, they can comprehend artificial language, including sign language and human speech. They display mirror self-recognition, memory, understanding of numbers, and tool use. They exhibit high emotional intelligence, including altruistic behavior. Dolphins form complex social relationships. Distribution Bottlenose dolphins live warm and temperate oceans. They are found everywhere except near the Arctic and Antarctic Circles. However, the dolphins living along shallow coastal waters are genetically distinct from those living in deeper water. Bottlenose dolphin range. maplab Diet and Hunting Dolphins are carnivorous. The feed mainly on fish, but also hunt shrimp, cuttlefish, and mollusks. Groups of bottlenose dolphins adopt different hunting strategies. Sometimes they hunt as a pod, herding fish together. Other times, a dolphin may hunt alone, usually seeking bottom-dwelling species. Dolphins may follow fishermen for food or work cooperatively with other species to catch prey. A group offshore from Georgia and South Carolina uses a strategy called strand feeding. In strand feeding, the pod swims around a school of fish to trap prey in the current. Next, dolphins charge toward the fish, pushing themselves and the school onto a mud flat. The dolphins crawl around on land to collect their prize. Predators Bottlenose dolphins are preyed upon by large sharks, such as the tiger shark, bull shark, and great white. In rare cases, killer whales eat dolphins, although the two species swim together in other regions. Dolphins protect themselves by swimming in a pod, evading attackers, or mobbing predators to kill them or chase them away. Sometimes dolphins protect members of other species from predators and other dangers. Reproduction Both male and female dolphins have genital slits that conceal their reproductive organs to make their bodies more hydrodynamic. Males compete with each other to mate with females during the breeding season. Breeding occurs at different times, depending on geographic location. Gestation requires about 12 months. Usually, a single calf is born, although sometimes the mother bears twins. The calf stays with its mother and nurses for between 18 months and 8 years. Males mature between ages 5 and 13. Females become mature between the ages of 9 and 14 and reproduce every 2 to 6 years. In the wild, bottlenose dolphin life expectancy ranges from 40 to 50 years. Females typically live 5 to 10 years longer than males. About 2% of dolphins live to 60 years of age. Bottlenose dolphins hybridize with other dolphin species, both in captivity and in the wild. Bottlenose Dolphins and Humans Dolphins display curiosity about humans and have been known to rescue people. They can be trained for entertainment, to aid fishermen, and to help find sea mines. Interactions between humans and bottlenose dolphins are usually friendly. George Karbus Photography / Getty Images However, human-dolphin interactions are often harmful to dolphins. Some people hunt dolphins, while many die as bycatch. Dolphins are frequently injured by boats, suffer from noise pollution, and are adversely affected by chemical pollution. While dolphins are often friendly toward people, there are cases of dolphins injuring or killing swimmers. Conservation Status Some local populations are threatened by water pollution, fishing, harassment, injury, and food shortages. However, the common bottlenose dolphin is listed as being of least concern on the IUCN Red List. Dolphins and whales enjoy some level of protection in most parts of the world. In the United States, the Marine Mammal Protection Act of 1972 (MMPA) prohibits hunting and harassing of dolphins and whales, except in special circumstances. Sources Connor, Richards (2000).

Boys and Boden Essay - 1110 Words

1.) To what extent could Dean expect to apply the philosophies and techniques of JIT described in this chapter to the running of a staircase cell. Dean Hammond can implement JIT techniques that seek to eliminate the significant amount of waste that exists in his current operational processes. Basically, there are seven wastes to be considered as obstacles in the lean system. It consists of over production, wasting time, transportation, process, inventory, motion, and defectives. As a result of implementing this concept, it will arrange a better-valued chain and create a solid base of production. While the customized nature of BB’s products isn’t conducive to the type of streamlining seen in volume manufacturing applications, they can†¦show more content†¦These same individuals could also be responsible for delivering these pieces to various stations, eliminating the need for the station workers to do so. By creating a staircase cell in their factory, BB can realize efficiencies that would allow them to eliminate waste and be more competitive in the areas of price and lead time. This would eventually reduce their order backlog, making their production more in line with estimates. 2.) What are likely to be the main categories of costs and benefits in establishing the cell? Are there any non-financial benefits which should be taken into account? BB may face some initial outlay costs in creating specific staircase stations. Additionally, there may be costs associated with training, as they ensure that their joiners can function as experts in their respective areas. This might even require a short period of inactivity or even a halt in production as they seek to get workers up to speed. However, the benefits seem to outweigh these initial costs. BB would be in a position to handle more volume and could make far better use of their existing resources. Orders would have a better chance of being completed on time and the elimination of waste would allow for more competitive quotes. Ultimately, this would put BB in a more competitive position to win business and become more profitable. 3.) At what stage, and how, should Dean sell his idea to the Joinery Manager and the workers?

Human Resource Management DHL Express

Question: Discuss about the Human Resource Management for DHL Express. Answer: Introduction DHL Express is one of the top multinational companies in the world and has been rated as one of the top companies to work with in the United Arab Emirates. DHL Express is a division of Deutsche Post DHL, which is a German logistic company. Deutsche Post DHL is the largest company in the world when it comes to logistics, particularly in sea and air mail. The company was originally started in 1969 with an objective of delivering documents between San Francisco and Honolulu while the company started to expand its business in other parts of the world during the late 1970s. At present, the company has a workforce of 325,000 employees and has expanded its business operations to a number of other business units, such as DHL Global forwarding and DHL Supply Chain (Greatplacetowork.ae, 2017). Some of the human resource practices that are being followed by the company are discussed below. Human Resource Management Practices At Dhl DHL, in UAE, has been ranked as the number one company to work for from a human resource perspective. Speed plays a very important role in the transport and logistics industry and is one of the most competitive factors amongst the rival firms but with the changing market trends, other factors, such as customer satisfaction, have also started to play a crucial role. As a result, the employees also have an important role to play in the present day logistic industry. Employees are now the backbones of all business organisations and it has become imperative for business organisations to look after the welfare of their employees in order to optimise their performance levels. DHL Express also believes in managing its human resource in a proper manner so that it can lead the global logistic industry. Some of the human resource practices followed by the company are discussed below: Performance And Motivational Training The Company has been planning for the training and development program for its workforce very efficiently. It has introduced learning establishments, such as DHL Asia Pacific Learning Centre. In 2008, the company launched a new program i.e. Deputy Country Manager Programme that was aimed at grooming the employees to take up higher positions in the company in the coming future. Under this program, a Deputy Country Manager is made to work under the guidance of a local country manager in another country and is developed in areas like human resource management, operations, CSR, etc. DHL Express should lay a greater focus on its training and development program but its greater focus on employee learning rather than focusing on actual motivation and performance can prove to be a weakness in the management process. To improve performance and motivation in the employees, DHL Express should design a number of On-the-Job and Off-the-Job training and development programs, such as group exercises, vestibule training, apprenticeship, mentoring programs, etc. that can help in training and developing employees in the short run. 360 Degree Online Feedback Program The 360 degree feedback program in the company was started in order to achieve three aims i.e. performance management, talent review and senior leadership development program. The online program allowed managers from throughout the world to provide feedback using a highly streamlined structure. The company has the right approach towards managing the performance of its employees using an online 360 degree feedback program but can improve it further to achieve better results. The company can also start a 360 degree feedback program in all of its business units in order to improve the output of the program. Using this program, all the employees (juniors or seniors) can review each others performance in a better way and contribute their best towards the management of performance. Career Development the company understands the importance of career development in the management of its human resources. The company has an International Business Leadership Program, which allows its employees to build strong cross-divisional networks and in becoming familiar with the business strategies of the company. The company has also enrolled a number of its employees in Executive Masters of Business Administration program so that they can improve their management skills and become experts in the field of logistics and finance. Career development is an important human resource management function and should be carefully planned in order to engage and retain employees. The company should also undertake some small scale strategies, such as job rotation, job enrichment, job transfer, etc. that can help the employees in learning new things and developing new skills that can help them in development their careers in the coming years (Right.com, 2017). Diversity Management DHL Express believes that its employees are an important factor in providing a reflection of the society in which it operates. The company has a large pool of talented employees who originate from wide range cultural, social and ethnical backgrounds. The company believes that a diverse workforce allows it to offer products and services to a diverse customer base. In order to ensure that there is high productivity, creativity and efficiency in the organisation, the company has committed itself to manage diversity and avoid any type of discrimination in the workplace. The company also has its own Code of Conduct that demonstrates diversity management as an integral part of the companys corporate culture. DHL Express launched a Diversity Respect initiative that was aimed at increasing the interest of people, belonging to various countries, in a career in its industry. The company has also launched Women in Leadership in order to promote female employees who have t he talent to achieve higher positions. DHL Express has taken a number of initiatives in order to manage and promote workplace diversity. A company operating in such a large industry and with such a global presence should definitely promote diversity in the workplace in order to serve a diverse customer base and the companys diversity management capabilities are proving to be a great strength in the global market. The company should also start undertaking expatriates programs and send employees for foreign assignments in order to promote workplace diversity at a greater level (Guides.wsj.com, n.d.). Employee Retention DHL Express has been able to maintain a very high retention rate as it has registered an employee turnover rate of 1%. The company has been able to retain its talented pool of employees by offering them promotions from within and promising them career opportunities. DHL also offers awards to its employees in order to retain them within the organisation. The companys ability to retain its workforce is proving to be one of its ultimate strengths that is also helping it in outperforming its competitors. The company is doing all the right things that are required to keep the employees engaged and retain them within the organisation. The company should also start a performance and potential appraisal system in order to make the work environment more performance oriented, which would ultimately increase the level of employee engagement and help in employee retention (Researchomatic.com, n.d.). Conclusion DHL Express is the global industrial leader when it comes to logistics and is one of the best companies to work with in the United Arab Emirates. The company has been performing exceptionally well when it comes to the management of its human resources, which is evident from the outputs that the company has been experiencing year by year. DHL Express has been following some of the best practices in the management of its human resources but the company can still improve a number of its human resource functions by undertaking new strategies and designing new programs that would improve the work conditions for the human resources and motivate them to work harder.
