Mugato

A Mugato is a non-sapient species of venomous simian-like predators native to the M-class planet Neural.

Biology
Mugatos are facultative bipeds which physically resemble Earth's apes, but can be distinguished by their shaggy white fur, a large horn on their heads, and a row of spikes on their backs that run down to the tip of a relatively-short tail. They also have three clawed digits on their hands, and four toes on their feet.

Mugatos are dangerous creatures. They possess venomous fangs that deliver a powerful toxin to which there is no antidote known to the Federation; although some natives of the planet are capable of curing the infected by using a local root.

Mugatos are active on both day and night time, and live together with mates. Although they don't seem to hunt together, a Mugato is never too far away from its mate.
