What makes a mammal, a mammal are the several characteristics that particular animal has.  For instance, all mammals have hair, as well as fat glands and sweat glands, female mammals also have mammary glands.  All mammals are vertebrates and also have several types of teeth.  Therefore, dolphins would not be classified as fish, they would be classified as mammals since they not only breathe air into their lungs, they have hair at some point during their life cycles, are warm blooded creatures, give birth to live young, and also nurse them with their mammary glands. i assume this was in a pro-life pro-choice argument tho so i don't wanna get into that. 67% Upvoted. Although dolphins have blubber instead of fur that help hold in its heat and give it a streamline shape, it is true that dolphins do have hair, but only a tiny bit.  The only place that they have hair is right next to their blowhole.  Though most dolphins do not have hair, they do have hair follicles.  These hair follicles are believed to perform some sort of sensory function.  For instance, the small hairs found on the Boto river dolphin are believed to function as a tactile sense possibly to compensate for the creature’s poor eyesight. share. For instance the killer whale (which is actually a dolphin) may be found swimming with up to three generations of family members within its […] Calves must eat quickly, as it is important for them to get back up to the surface to breathe.  It is because of this that unlike most mammals that are equipped with a way to suckle their mother’s milk, dolphin mothers instead have specialized muscle contractions that squirt milk into the calves’ mouth.  Dolphin calves grow very quickly on the high fat of their mother’s milk, and in some species have even been known to double in weight within a mere two weeks.

At first glance, sharks and dolphins may seem to be similar in size and shape, though sharks obviously appear to be stronger for obvious reasons already mentioned.  However, when taking a closer look there are many differences in the two that can be noted and give the dolphin quite an advantage.  Sharks are an ancient fish with skeletons of cartilage, where dolphins are descended from mammals that have returned to the sea and sport skeletons with hard, calcified bones.  The skeletons of sharks have joints that are not as flexible as the dolphins. However though they lack in this department, it should not be assumed that they are not efficient in their other senses.  In fact they have acute eyesight both in and out of water and they can hear frequencies ten times or more above the upper limit of adult human hearing.  A dolphin’s sense of touch is also well developed, with free nerve-endings densely packed into the skin, especially around the snout, pectoral fins and genital area. After this, dolphin mating is about the same as any other mammalian mating. When a dolphin is positioned below a shark at a distance of several yards, the dolphin will often make a sudden rush at the shark’s soft underbelly and ram it with its snout.  The effect this has on the shark can be quite effective.  It resembles a powerful punch and can seriously injure a shark with just one blow.  When dolphins use this as their weapon against sharks, it often renders the shark stunned or knocks them unconscious immediately.  Sometimes a dolphin will repeatedly ram a shark that has been aggressive in order to protect itself or its group, and in some cases have even been known to kill large and dangerous sharks.  In most cases, even if the shark does not die as a result of the dolphin driving its snout into its underbelly, the force that it has on the shark will often leave some kind of internal damage. Lol ok hang on I gotta go break up with a bunch of people. Is a Penguin a Bird, Mammal or Amphibian. When aroused, a dolphin male may even mate several times an hour, often with the same female but not always. Yes, dolphins can and have been known to kill sharks.  As many know, dolphins and sharks inhabit the same regions and depths of the ocean.  Sharks have a reputation for being fierce predators, and are armed with rows of sharp nasty teeth that help them bite through flesh and bone with ease.  They also have very tough, sandpaper- like skin that is not easily punctured.  Whereas dolphins are often viewed as the intelligent, playful, friendly mammals with only a single row of peg-like teeth used mainly for catching smaller fish.  Their skin, unlike the sharks is soft and flexible and can be punctured easily.  Dolphins surprisingly, have however often been seen protecting an injured or sick member of their group or extended family, often from a shark attack.  They have also at times been known to protect humans from sharks in the water and in some cases have even been known to carry a human safely to shore. they're wrong, but i actually agree with their sentiment on a personal level. Dolphins are an interesting character and lack olfactory receptors (interestingly enough, the olfactory tract and bulb only exist in the fetal stage of development) therefore, it is true that dolphins do not have a sense of smell. 2 comments. Since dolphins normally travel together in groups, if one of the group is threatened by a shark, the other dolphins will join in without hesitation to do its best to defend the dolphin that is in danger.  The dolphin’s main weapon against a shark attack is its snout, which is made up of very strong and thick bone and has a hard rounded end.  The dolphins circle the shark rapidly from different directions thus confusing the shark and rendering it unable to chase any of the other dolphins.
