Feather Blenny
Hypsoblennius hentzi
Size: to 5″
Habitat: bays, estuaries, protected coastal waters
Notes:
Blennies live on the bottom in oyster beds or mussel beds. If you find an old piece of pipe or a bottle in the river, look inside – you’ll probably find a blenny.
Feather Blennies have branching “horns” over the eyes, called cirri.
Similar Striped Blenny has a more pointed profile with almost invisible cirri. I have not yet encountered the third and final species of blenny in our area – the Seaweed Blenny.
