Titanomyrma

Wild

Titanomyrma is one of the smaller creatures on the Island; a frightening thought, when you realize it is the size of a dog. A hive-minded carnivore, Titanomyrma is aggressive on sight to humans and their creature companions. When attacked or threatened, it releases a chemical which alerts all other Titanomyrma in a large range to help fight the aggressor. While small, Titanomyrma remain a threat because of their bite. Titanomyrma mandibles produce a toxic venom that causes loss of stamina, preventing escape and increasing the chance of losing consciousness. I've seen two varieties of Titanomyrma: Drones and Soldiers. Drones are smaller, faster, and land-bound, with the intent to harvest for the colony. Soldiers are larger, slower, have wings, and they defend the colony. If Titanomyrma is akin to hive insects, there must be queens too, but I've yet to encounter such a variant.

Domesticated

Because of its hive mentality, I've not seen any successfully tamed Titanomyrma on the Island yet. Fortunately for lone survivors, separated Titanomyrma can be easily picked off for a small supply of chitin among other natural resources.
