Morphology

The eastern frogfish has a flattened head with a wide mouth surrounded by a distinct fleshy 'beard'.[3] Its colour varies from mottled brown to pale grey or bluish-grey, with two broad bands and scattered splotches along the body.[1] Juveniles are paler with broad bands. They reach a maximum length of 35 cm.
