"Seahorses are one of two groups of animals (along with pipefish) where the male carries babies to term. First, the lady seahorse deposits her eggs in her man’s brood pouch. The eggs are internally fertilized with the male’s sperm, and after a 10 to 25 day gestation period, he churns out a brood (clutch, litter, swarm?) of tiny, fully-formed seahorses. Thousands of them."
