Are dolphins and whales still being used for tuna?
The tuna is caught with huge nets by large fishing boats. The boats hunt the tuna through finding dolphins since the tuna run under the dolphins. They spread out nets and to round the fish up they set off small blasts in the water. This confuses the dolphins that are in the area and they begin to draw up the nets with big rollers on the ship. As they pull the net they collect the tuna and some of the dolphins. The dolphins try to jump out of the nets, get caught in the nets and drown, or are pulled in with the tuna. Eventually , the load of tuna is pulled in and placed in the hold of the ship. Some ships pack and can the tuna right there. Others take the tuna to packing houses. In recent years there have been efforts to stop the number of dolphin deaths in the process. Whether, this has really been done or not is debatable. This why some tuna companies cite on their product that the tuna is "dolphin safe".
In what sea do dolphins live in?
Dolphins live in every ocean in the world. Some are better suited for colder ocean water than others, but they can live everywhere.
A human swimmer must use a snorkle to breath while swimming just below the water's surface. Aqualungs (air tanks) are used to breath under water, and allowing the swimmer to diver deeper. Goggles are used to help a swimmer to see under water.
Dolphins do eat cod and other variety of foods. Orcas are larger dolphins that eat sea lions and sea turtles.
What is the common porpoises habitat?
Porpoises live in the cold waters of coastal bays, tidal channels and estuaries of the Northern hemisphere. There are many along the east and west coasts of North America, the North Sea and the British Isles. They are most commonly seen along the continental shelf (about 6 miles off shore) and usually in water less than 300 feet deep.
Can a man stick his penis in a dolphin's blowhole?
No, I'm about 100% that it is illegal. (It suffocates the dolphin ya know!)
Yes they can. Dolphins are aquatic mammals so they have to sleep in the water. They cannot live on land. Only one side (hemisphere) of the dolphin's brain goes into deep sleep. The other hemisphere stays alert to allow the dolphin to surface for air and to watch for predators.
I think you meant, what do Dall sheep eat so here is my answer.
During the summer when food is abundant, the sheep eat a wide variety of plants. During the winter diet is much more limited and consists primarily of dry, frozen grass and sedge stems available when snow is blown off, lichen and moss. Many Dall Sheep populations visit mineral licks during the spring and often travel many miles to eat the soil around the licks.

What are some things that dolphins teach their calf?
what are some things that the mother dolphin does for, or theches, her calves
Dolphins require very large bodies of water for their survival. States that accommodate this type of lifestyle include California, Hawaii, Washington, Florida, Georgia, and states along the Atlantic Ocean.
Dolphins are one of the most friendly animals on the planet. The only time they would actually bite is if they feel that they are threatened by people. They would also bite if they were wild and people would be feeding them. They can sometimes mistaking people's hands for food and bite them since they are wild. A trained dolphin shouldn't bite people, unless something goes wrong....Hope this Helps! :)

Why do whales and dolphins belong to the same group of mammals?
Mammals (class Mammalia) are group of vertebrate animals in which the young are nourished with milk from special mammary glands of the mother. In addition to these characteristic milk glands, mammals are distinguished by several other unique features. Hair is a typical feature, although in many whales it has disappeared except in the fetal stage. This ability to feed the offspring with milk occurs in whales as well.
What body plans do dolphins have?
Cetaceans, the zoological order including whales, dolphins and porpoises, have a streamlined, bilaterally symmetric shape. They all possess flukes (horizontal, flattened tail structures at the end of the caudal peduncle) and pectoral fins (which vary in size and shape). They may or may not possess dorsal fins, with variations ranging from the tall dorsal fin of the orca ("killer whale") to the absent dorsal fin of the beluga whale and others.
