Why is the presence of echinoderms like sea urchins particularly telling about a wolffish's feeding strength?
Answer
They require significant force to breach their defenses.
Sea urchins, which fall under the category of echinoderms, possess rigid, heavily defended bodies that present a significant mechanical challenge to predators. The inclusion of these animals in the natural diet of the wolffish serves as a strong indicator of the sheer crushing power the fish can generate, as successfully consuming them requires overcoming substantial structural resistance. Unlike softer prey, breaking through the spines and tests of sea urchins demands the full deployment of the fish's molar-like teeth, validating their status as apex benthic predators adapted for hard-bodied fare.
