What is the difference between a dolphin and a porpoise? I heard this question asked, on Johnny Carson. And, Johnny decided that a dolphin was a mammal, and a porpoise was a fish. Wrong. They are both mammals, and are very closely related. The porpoises have a rounded head, while the dolphins have a protruding snout. They are smaller members of the toothed whale family, to which killer whales and sperm whales belong.\n\nTo complicate things, there are a couple of fish which are also called dolphins. I assume that these are sometimes called "dolphin fish" to avoid confusion. But, the well-known dolphins are those cute mammals, like Flipper (who is a bottle-nosed dolphin).\n\nMammals have hair, breath air, give birth to live babies (platypuses and echidnas lay eggs), and feed milk to their young. Whales breath air (they can hold their breaths for long times), give birth to live babies, and feed milk to their young. Where is their hair? Evidently, they have a small amount of hair around their blow-holes, those holes, in the top of their heads, that they breath through.\n\nThe toothed whales are among the most intelligent of all animals. The killer whale (orca) apparently has a brain mass to body mass ratio (a rough measure of intelligence) which is greater than that of humans. Incidentally, while toothed whales are predators, there is no record of any killer whale ever having killed a human being.

It will vary from dolphin to dolphin. Certain dolphins will prefer different rewards over others. That is why dolphin trainers learn the personalities of the dolphins to see what they like as a reinforcement. Just like dogs, they preference over certain things.

I think a Alligator is a different Genus, and that physically A crocodile has a pointy snout, whereas a alligator has a round one. Hope it helps.

yes they are aroused, but not by the same things as us. Yes they have the same mechanical processes as we do for an orgasm.  Although I'm sure they don't have the emotional hangups that we do.  And dolphins aren't the only other animals that have sex for recreation.  There is a primate called the Bonobo that pretty much has sex all the time. Male-female, same sex, masturbation....whatever, they don't care.

It depends on the kind of dolphin you're talking about. \n\nThe most commonly thought-of kinds of dolphins, which look a lot like porpoises, are air-breathing mammals. They are typically 5 to 8 feet long.\n\nBut there is also a dolphin fish, also called a pompano or mahi-mahi, which is a true fish and not a mammal.  Dolphin fish are brightly colored, have large heads, and are typically two to three feet long. These are the kind of dolphins seen on the insignia of US Navy submariners.

Dolphins are born after a gestation period of 12 months. They are weaned at 9 months and become able to breed at the age of 8 years. The female dolphin will have one baby each year until she stops all breeding at the age of about 14 years. Life expectancy is 25 - 35 years.

The dolphin's life can be, at times, very confusing. To make this easier to understand, we have made a cycle showing you the dolphins life. Like humans, dolphins are mammals. They give birth to live young. The only mammal that doesn't give birth to live young is the Platypus. Dolphinsare considered as one of the smartest animals in the world!  There life starts out when there babies, and when they grow older they choose which direction that their going to take. Most babies will stay with the pack that their mothers are in. When they are adults, they will find a mate. During the mating season, reproduction will occur.

There is.  Dolphins and monkeys are as intelligent as humans, just in a different way.  Dolphins have their own language that they communicate in and it has been proven that they are of equal intelligence as humans.  There are plenty of animals out there that are as intelligent as humans just in different ways.

No, the plural of porpoise is porpoises.  The only time "-i" is used as a plural ending is with words taken from Latin ending in -us (for example, the plural for streptococcus should be streptococci).

It depends which species you are talking about--the Killer whale (Orcinus orca)is the largest dolphin. Male killer whales can grow up to 9.6 m (31.5 ft).  There is not really one smallest species. The smallest species include: True dolphins (Delphinidae): Tucuxi (Sotalia fluviatilis) - 1.3 to 1.8 m Hector's dolphin (Cephalorhynchus hectori) - 1.2 to 1.5 m Black dolphin (Cephalorhynchus eutropia) - 1.2 to 1.7 m Commerson's dolphin (Cephalorhynchus commersonii) - 1.3 to 1.7 m.
