What’s the difference between a snake and an eel?
Eels have gills, as most other fish do, and filter air from the water in order to breathe. This means that they never have to go to the surface. Snakes, on the other hand, do not have gills, but lungs.
Are eels evolved from snakes?
The evolution of land snakes was started by sea snake kraits with lungs, who had evolved from eels perhaps 190 million years ago and around 90 million years ago made land their permanent home and became land snakes.
What are eels classified as?
Eels are ray-finned fish belonging to the order Anguilliformes (/æŋˈɡwɪlɪfɔːrmiːz/), which consists of eight suborders, 19 families, 111 genera, and about 800 species. Eels undergo considerable development from the early larval stage to the eventual adult stage, and are usually predators.
