Other characteristics of dolphins that make them mammals rather than fish are that they give birth to live young rather than laying eggs and they feed their young with milk. Also, like all mammals, dolphins even have a tiny amount of hair, right around the blowhole. Whales and porpoises are also mammals.

How does a dolphin give birth?
Dolphins give birth to a single baby; the baby is usually born tail first (unlike most mammals) to minimise the risk of drowning. The birth can take a couple of hours. The newborn dolphin is fully dependent on his or her mother and suckles thick paste-like milk from her nipples until he or she is able to catch fish.
What animal does not lay egg?
Birds, insects, reptiles and fishes are oviparous animals. Animals which reproduce by giving birth to their young ones are called viviparous animals. These animals do not lay eggs. Mammals like cat, dog and man are viviparous animals.
Is there a mammal that can lay eggs?
Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater. These odd “monotremes” once dominated Australia, until their pouch-bearing cousins, the marsupials, invaded the land down under 71 million to 54 million years ago and swept them away.
Does dolphin produce milk?
Cetaceans nurse their young just like land mammals do. Unlike the exposed nipples of humans and our closer kin, the mammary glands of dolphins and porpoises are concealed inside of abdominal slits. The mother squirts the milk into the calf's mouth to account for the difficulty of underwater suckling.
Do dolphins eat their babies?
–Dolphins kill their own babies. Baby dolphins have washed up alongside the dead porpoises, and some scientists think that all the porpoise-slaughter was just practice for some old-fashioned infanticide . ... The dolphins didn't even need to make up sleep at the end of the study, though the scientists sure did.
How long is the mother dolphin pregnant?
Pregnancy. Recent research indicates that bottlenose dolphin pregnancy lasts about 12 months (Wells 1987). During this time, there is very little room in the uterus for a baby to develop. As a result, and to make birth easier, the tail fluke and dorsal are cartilaginous and are folded over in the uterus.
Does frog lay egg?
Most frogs and toads begin life as eggs floating in the water. A female may release up to 30,000 eggs at once. Each species of toad and frog lays eggs at different times. ... Frogs lay them in clusters, or large globs.
Do penguins lay eggs?
All penguin species must return to land or ice for breeding. They will time breeding to an optimum time for productivity in the ocean for finding food to their chicks. Emperor and king penguins lay one egg while all other penguins lay two eggs. When laying two eggs, they are spaced between 24-48hrs apart.
Do sharks give live birth?
There are over 500 species of shark living in waters around the world and the majority give birth to live young. The remainder are oviparous, meaning they lay eggs. ... Among them are egg layers such as the small-spotted catshark (Scyliorhinus canicula) and nursehound (Scyliorhinus stellaris).
Do kangaroos lay eggs?
Kangaroos do not lay eggs because they are marsupial mammals that give birth to live young. Kangaroos usually give birth to one baby that stays in their pouch for at least 6 months, considering that the baby is born very undeveloped.
Is a penguin a mammal?
Penguins, or Sphenisciformes, are not mammals, but birds. They are different from mammals in that they have feathers instead of hair or fur, and unlike most mammals penguins lay eggs instead of giving live birth. ... Unlike mammals, penguins lay eggs rather than giving live birth.
Do otters lay eggs?
The lifespan of a female otter is 15 to 20 years and of a male otter is 10 to 15 years. They do not lay eggs and instead give birth to their young ones, mostly in spring.
What are baby dolphins called?
A baby dolphin is called a calf. This is also the name we give to baby whales and baby cows. Usually, dolphins only give birth to one calf per...
Do dolphins give live birth?
Dolphins give birth to live young and do not lay eggs. They can get pregnant on average every two to four years once they're mature, although some species can have 5-7 years between births.
Do whales lay eggs?
Do whales lay eggs? The answer is no. Because whales are marine mammals, the females carry the offspring in their wombs and have live births! However, since whales are fully aquatic mammals, how whales give births is much different than the births of terrestrial and semi-aquatic animals.
