Animals That Start With E

Corallus caninus

The emerald tree boa is a non-venomous constrictor found in the rainforest canopy of the Amazon and Orinoco basins, spending nearly its entire life coiled in trees and rarely descending to the ground. It's a striking example of convergent evolution: the unrelated green tree python of New Guinea and Australia — a completely different snake family from a different part of the world — has evolved an almost identical bright green color, white markings, and coiling posture to fill a very similar ecological niche.

Aptenodytes forsteri

The emperor penguin is the tallest and heaviest of all penguin species, uniquely breeding through the brutal Antarctic winter on sea ice far from open water.

Dromaius novaehollandiae

The emu is the second-largest living bird in the world by height, a flightless giant native to the open plains and deserts of Australia. Despite being unable to fly, it's an exceptionally fast and powerful runner, capable of covering long distances across the outback in search of food and water.
