These pigmented nodules encase bundles of nerve fibers innervated beneath by branches of the trigeminal nerve.
Despite the fact that crocodiles, alligators, along with the gharial are related in visual appeal, they belong to independent biological families. The gharial, with its narrow snout, is less complicated to differentiate, whilst morphological variations are harder to spot in crocodiles and alligators.
