It also has close, fine set teeth. It does not have as thin a physique as most fish its size as it mostly dwells at the base of shallow water, needing less aerodynamic adaptation.
Habitat: H. hentz ranges from New Jersey to the Yucatan. It is also a year round resident to the Chesapeake Bay and near grassy beds and rocky shores.
Feeding: Blennies prefer to eat small crustaceans and mollusks.
Breeding: Spawning occurs from May to August. Males entice females to lay eggs in empty oyster shells and then guard the eggs after they are laid. There are approximately 3,500-4,000 eggs per batch with planktonic larvae often found in shallow, coastal waters.
