Which is most likely to care for its young, a mammal or a fish? Why?

Answer 1

Mammals.

"Why" is a rather difficult question. There are lots of possible answers... most likely, though, the answer you are looking for is the development of the young. Mammals are born wet, cold, and helpless. Fish are hatched wet, cold, and quite well suited to care for themselves. As a result, mammals have to care for their young or they would mostly die.

As I said, there are other answers.

Probability? The percentage of mammals which care for their young is 100%; the percentage of fish which care for their young is very small (although some do exist... take clownfish for example. Remember Finding Nemo?). Hence, a mammal is more likely to care for its young than a fish.

Instinct? Most mammals instinctively take care of their young; most fish do not.

Answer 2

A mammal. A fish may lay thousands of eggs during a breeding season while a mammal may have only one young. At most a mammal may have several (up to 6 young). If the thousands of eggs were actually born, there is no way that one fish (or even two fish, if the fish were monogamous) could care for that many babies. Besides, mammals typically need more parental care (at least the mother). A young mammal needs the mother to provide it with food (i.e. milk) and to care for it until it is old enough to care for and protect itself. Most mammals are able to take care of themselves by 6 months to 1 yr. of age. It depends on the species of mammal.

Answer 3

The mammal, is most likely to care for its young. The mammal gives live birth and the fish lays thousands of eggs. So the mammal giving live birth to a much smaller number tends to take more care of its ofspring. The fish lays the eggs and goes on and forget them most of the time.

Answer 4

A mammal. They give live birth, and get to see the child. A fish lays its eggs and then leaves--it might even eat its own young if fate puts the little one in front of its mother.

Answer 5

A mammal, because since it has to give it milk it won't leave it until the young is old enought to care for itself. unlike "most" fish, they just take care of the eggs untill they hatch.... but some actually take care of them when they are born, like the Amazonian Discus Fish.....

Answer 6

Mammals. By definition, mammals nurse their young ('mammaries'). Fish do not.

Answer 7

Mammals, of course, since they take longer time to take care of their babies before they come out in the real world. Also, mammal mothers of any species gives its' nutrients to its' embryos, when they are in the uterus, via the placenta.

Answer 8

a mammal cause we give birth and nurture are young and fish just lay eggs and leave

Answer 9

Mammals, fish don't breast feed. I have never seen a fish with nipples.

Answer 10

mammals bec it needs its mother to get its milk
or it will die
but fishes can lay its eggs in a safe place
secondly fishes laying eggs with huge amounts
and vice versa with mammals
