## Description

Lestognathans are a clade of malleognathans that specialized for kleptoparasitizing related species. The evolution of the lestognathans is closely tied to the echinostracins: due to their powerful, spikey armor, the malleognathans with their robust jaws were one of the only animals that could make them into a regular food source. Because this food source was virtually uncontested, some of these malleognathans instead started to specialize in stealing from other malleognathans that have already done the work of cracking the hard, spiny shell open, and became the lestognathans. Lestognathans have less powerful jaws than other malleognathans, but are generally larger to more easily bully echinostracan hunting malleognathans off their kills.
