Skullatrax
This eusocial Kreature was designed for point-defense and ambushes against infantry. It's armed with oversized fangs dripping with venom and protected by a hard exoskeleton composed of mineralized tissues resembling bone. It spins a series of webs which act as trip-wires; when its prey comes into contact with the web, the last thing the hapless victim hears is a cacophony of rattling, skeletal limbs as the colony swarms over them and closes in for the kill. They're best kept in groups of at least three, as they'll become stressed when not making physical contact with each other. Colonies consist of a mother and her brood of offspring. In feral colonies, the most dominant member of the brood takes over if the mother dies. In captivity, their Tamer will assume that role instead.
