Desidae

Desidae are fan-made temnocerans, created by FeralJinouga.

Physiology
Desidae are large, flat bodies temnocerans that bear a striking resemblance to real world amblypygids. Their carapaces are dark brown with lighter brown spots on them, and often have moss growing on them. They have four legs, which are long and thin, and angled in such a way that allows the desidae to remain close to the ground. They also have two large, club like claws that are covered in long spikes. Their last set of limbs is very unique. It is covered in a multitude of sensory hairs, and is used in a similar fashion to an insects antenna. These limbs are incredibly thin, three times the size of the body, and incredibly flexible. In front of their mouths are two claws that are used to mash food into a pulp. Similar to scorpions, they also have pectines on their underside, and use these to track pheromone trails.

Behavior
Desidae are ambush predators, burrowing just beneath the ground and keeping their sensory limbs right above the ground in front of them. When these limbs sense prey, the Desidae pounces, using its spiked claws like clubs to crush their prey. Juvenile desidae have become a major pest in some regions as they find their way into farms and terrorize the live stock.
