The Soricada is a work of fiction.

The name is taken from a Sorex hoyi, or The American Pygmy Shrew. It is one of the hungriest animals on Earth, much like the Soricada. Hopefully you can see that Sorex = Soricada.

Ego’s joke (of which he is very proud) is derived from the combination of “Taming” and “Shrew”. Now, aren’t you glad that you took the time to look it up?
