What life cycle adaptation allows a seahorse to make lots of babies in a short amount of time? (2 points)
Zielflug [23.3K]

The seahorse make a lot of babies because the male carries the babies while the female makes more eggs.

<h3>What is mating?</h3>

Mating is the process in which opposite or hermaphroditic organisms pair for reproduction.

During mating between the male and female seahorse mates, the female seahorse puts her eggs in the male pouch and the male fertilises the egg in his pouch. The eggs develop into baby seahorse in the father pouch.
