Poachers (Agonidae) are a group of bottom-dwelling fishes characterized by their bony armor. Though these fish are heavily armored, they still face predatory pressures. We have CT and SEM data from more than 30 Northern Spearnose Poachers that show extensive damage to their bony plates. A potential threat in their natural habitat is the Red Rock crab (Cancer productus), which typically use their claws to process prey. We are interested in whether the damage that we see done to the armor could be caused by Red Rock crab claws. To this end, we gathered video of Red Rock crabs eating agonid carcasses using a GoPro rig and analyzed their feeding behavior. We then collected the damaged scales and imaged the damage done by the crab in a scanning electron microscope. The damage we found matched up with our previous images of damaged poacher plates. We were able to replicate the damage with machine milled crab claws in a material testing system and our data confirms the crab’s capability to crush through Agonopsis vulsa’s armor. We found that the damage applied by the material testing system and natural crab predation were similar enough to conclude that there’s no trick: the crab is crushing the armor with a force that a crab could realistically generate. We also found that the crab usually starts eating at the head of the Agonopsis, which we will look into further in order to determine if this is a behavior that is replicable in the wild. While the armor of the Agonopsis vulsa does not offer protection from crushing crab claws, it may offer enough resistance to help increase the chance of survival in an initial interaction or protect from other factors in its environment.
