The Brown Snurtle

My animal is a black mamba, which lives deep in the rainforest. The black mamba lives round trees and bushes and sleeps in hollow trees, burrows, rock crevices, or empty termite mounds, and will come back to the same place every night. The black mamba is a fast, dark colored, nervous, lethally venomous, and when threatened, highly aggressive snake. The black mamba feeds on small mammals such as mice, squirrels, rats, and birds. A thousand years later the black mamba has changed and evolved into an animal way different than its original form, The new animal is called the brown snurtle. The brown snurtle is a black mamba but has grown traits of a sea turtle to survive the ocean. It lives in the shallow water but more commonly found along the ocean floor. The brown snurtle feeds off of small fish and shrimp. It is aggressive, venomous, and intelligent.
