While they look very different from the typical fish we imagine, they are classified as bony fish (Osteichthyes) and belong to the family Syngnathidae.
Here's why:
* They breathe with gills: Like all fish, seahorses use gills to extract oxygen from the water.
* They have fins: They have small, transparent fins that help them maneuver and stay upright in the water.
* They are cold-blooded: Seahorses maintain their body temperature based on the surrounding environment.
* They lay eggs: While the male seahorse carries and incubates the eggs, they still reproduce via eggs.
So, even though they have a unique appearance and live in a different way than most fish, seahorses are definitely classified as fish!
