The female gives her eggs to the male, and he carries them for a month. Every morning, they dance together. Seahorses are truly amazing creatures. Part 2 Chameleons and seahorses are both amazing. They can both change colours. Chameleons can move their eyes in two different directions, but seahorses cannot. Chameleons eat their dead skin, but seahorses do not. Seahorses dance every morning, but chameleons do not dance. The biggest difference is that male seahorses can have babies, but male chameleons cannot.
