This appears to be the most abundant blenny on the North Carolina coast, 

 whence it ranges to Texas. The maximum length is about 2.5 inches. Dr. 

 Coker contributes the following note on the species at Beaufort: 



Adults very common about piles of wharves (at the Morehead railroad pier), living 

 amongst ascidians, sponges, etc.; very abundant among the rocks of the Fort Macon jetties. 

 In captivity the fish seek to hide under shells, etc.; specimens were once kept in the laboratory 

 in an earthenware jar for weeks without change of water, the water meanwhile evaporating 

 nearly one half. The eggs are laid [in August] in a single layer, attached to the rocks, ascidiaoas, 

 shells, etc., among which the adults live. All stages, from .5 inch up to adults, can be gotten
