Warmtsudo

The warmtsudo split from its ancestor, the walking tetsudo, and moved north, to the Barlowe Tundra. The need to survived made the warmtsudo rely less on iron flora, and more on the iron rich tundra rustling, which it captures with its huge mandibles and crushes it into small chunks it can easily fit into its elongated mouth.

Its body has changed over the millions of years in the tundra. Its feet are now smaller and chunkier than its ancestor's, and its carapace is larger, to help retain fat, and stay warm. Its ear-flaps grew smaller, to allow for less heat lost, and its mandibles, though bigger, have little blood transported to them, hence the difference in color to the rest of the body.

Its breathing-reproducing holes changed and split to reproduction holes and breathing holes. The first are on its sides, allowing for easier transportation of genetic material. The last are over the front and back of the shell.
