An amphibious Crustaceoid, capable of terrestrial survival but strongly driven to remain submerged. Powerful ventral suckers can hold fast to prey while the beak-like feeding siphon injects a digestive enzyme and feeds via suction. Fish are its preferred food.
BASE ORGANISM: Argulus are aquatic parasites well adapted to feeding on bony fish, their flattened bodies ideal for clinging to scales. Argulus may spread diseases from one host to the next, occupying a niche similar to terrestrial ticks.
