Feather Blenny

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 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.

When I was cleaning his aquarium once, this little bugger swam up and bit my hand, and left a mark !!! They have very strong jaws.

Unlike ( or just like ) the Caribbean, diving in New Jersey is actually better at night in many ways. That's obviously not true if you are out to survey a shipwreck, but for inlet diving, there is no comparison. During the day, the day critters will be wide awake, and you won't be able to get near them, while the night critters will be down in their holes where you'll never see them.

At night, you can go right up to the sleeping day critters and pinch them, even the fish. Some even seem mesmerized by your light, which will also draw in many small invertebrates by itself. Meanwhile, the night critters will be out prowling around, including the king of all night critters, the lobster. And if you shut off the light and wave your hands vigorously, the bioluminescents will put on a show for you.
