Transcript: Dolphin Slaughter Between Early September and late march Slaughter of 2300 dolphins annually Tradition that goes back centuries How they do it Go out to open sea Bang hammers metal poles underwater to herd the dolphins to a cove that are sealed off by nets Held captive overnight At sunrise they use harpoons, knives and spears to kill the animals What it is used for... MONEY Government advisory limit is .4 parts per million A test of an internal organ of a dolphin was found to have Celebraties are even getting involved with the cause The dolphin slaughter is all over the media to make people more aware of the problem A very important documentary called, The Cove was released in 2009. This film was shown all around the world to inform people on the horrific events that is taking place "I have to see this end in my lifetime. Right now I am focusing on that little body of water where the slaughter takes place. If we can't stop that, forget about the bigger issues. There's no hope." -Ric O' Barry In conclusion... The world's course of action should be to make and enforce better whaling laws in not only Japan but the entire world We could be potentially wiping out an entire species This will have effects on the marine eco- system The biodiversity of all marine life is dependent on this species After the slaughter, the dolphins are taken to a warehouse where they will be butchered and sold atlocal supermarkets and restaurants Where It Happens... What people do not know is that dolphin meat contains extremely high levels of mercury 2,000 parts per million What is being done? Strict laws are being put into action about the slaughters, but because Japan holds a lot of power, the IWC cannot do much about the problem Toxic for HUMANS Fishermen can receive an immense profit from the dolphins Before the slaughter, dolphins can be sold for more then $150,000 Dolphin meat can be found throughout Japan in local supermarkets, restaurants, and even on school lunch menus


Transcript: Dolphins eat squid sand crustaceans, such as shrimp. Dolphins do not chew their food. They swallow i whole. They swallow fish head first so that the spines of the fish won't catch in their throats. Dolphins live in harbors, bays, lagoons, gulfs and tributaries. They do migrate if the water gets cold enough. Also they may migrate if the fish supply and feeding habits change. Some like cold and deeper water than others. Did you know . . . ? Dolphins are not endangered They can jump up to 20 feet above water Their brain is bigger than the monkey They have 100 teeth Some kinds of dolphins can hold their breath for 30 minutes The Boto is the largest dolphin The dolphin may eat up to 30 pounds of fish a day The baby dolphin can stay with his mother for two to three years The dolphin can live to be 50 years old Smell: they have a limited sense of smell. Taste: they do have taste buds. Hearing: Their hearing is GREAT! They can hear 1 to 150 kHz per second. While humans can only hear 2 to 12 per second. Eye Sight: Their eyes are adapted to water. They have 2 eye lenses, although we only have 1. . One common feeding method is herding, where a pod squeezes a school of fish into a small volume known as a bait ball. Individual members then take turns plowing through the ball, feeding on the stunned fish various methods of feeding exist among and within species methods of feeding exist among and within species Fish and squid are the main food, but the false killer whale and the orca also feed on other marine mammals. dolphin Dolphins are marine mammals closely related to whales and porpoises.

Transcript: Dolphins.! Dolphins are marine mammals that are closely related to whales and porpoises. There are almost forty species of dolphin in 17 genera. They vary in size from 1.2 m (4 ft) and 40 kg (90 lb) (Maui's dolphin), up to 9.5 m (30 ft) and 10 tonnes (9.8 long tons; 11 short tons) (the orca or killer whale). They are found worldwide, mostly in the shallower seas of the continental shelves, and are carnivores, mostly eating fish and squid. The family Delphinidae is the largest in the Cetacean order, and evolved relatively recently, about ten million years ago, during the Miocene. Dolphins are among the most intelligent animals, and their often friendly appearance and seemingly playful attitude have made them popular in human culture. Reproduction.! dolphins can court or play for days. They swim together and pet each other with their fins. The actual mating is brief and it lasts only one to two seconds. Reproduction normally occurs during the spring months. Males make elaborate swimming patterns and calls. Whether this is done to show off their fitness or to show other dolphins that he has coupled with a female is unknown. Females have a short period in every few years when they are fertile. Gestation takes between 11 to 12 months. Gestation is how long the female dolphin is pregnant. The delivery of the baby dolphin is usually tail first, because if the calf is born head first, it won't be able to get to the surface in time to breath. Female dolphins can retain the ability to produce milk long after they lose the ability to make babies. Inexperienced females will care for the calves of other females to gain experience. Feeding.! Communication.! While it is not known if dolphins have a formal language, they do communicate with a signature whistle to identify themselves. Unlike humans, dolphins lack vocal cords, but they do use a complicated system of whistles, squeaks, moans, trills and clicks produced by sphincter muscles within the blow hole. Habitat.! Dolphins live in harbors, bays, lagoons, gulfs and tributaries. They do migrate if the water gets cold enough. Also they may migrate if the fish supply and feeding habits change. Some like cold and deeper water than others. Behavior.! Dolphins can leap above the water surface and perform acrobatic figures (e.g. the spinner dolphin). Scientists aren't quite certain about the purpose of this behavior, but it may be to locate schools of fish by looking at above water signs, like feeding birds. They could also be communicating to other dolphins to join a hunt, or attempting to dislodge parasites. Perhaps they just do it for fun. Play is a very important part of dolphins' lives and they can often be observed playing with seaweed or playfighting with other dolphins. They have even been seen harassing other creatures, like seabirds and turtles. Frequently dolphins will accompany boats, riding the bow waves. Dolphins are “opportunistic” feeders, meaning they will eat those fish, squid and crustaceans (such as shrimp) available to them at that time. The variety of foods available is dependent upon the geographic location of the feeding population. Dolphin populations living along coastal areas tend to eat fishes and invertebrates which live on the coastal bottoms. Dolphins living in deeper parts of the oceans tend to eat fishes and squid which swim in the marine mid levels. Adult dolphins eat about 15-25 pounds of food per day (about 4-6% of their body weight), with nursing cows eating over 30 pounds per day (about 8% of their body weight).
