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 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.

I have found no correlation between good visibility and anything else at all. Calm seas certainly don't hurt, but the worst visibility I have ever been in was with a 1-foot surf on the beach. There is however a very good correlation between bad visibility and storms, which is why a single hurricane can end the season.

Other factors which influence visibility are: algae blooms, spawning seasons of some invertebrates, which can fill the water with tiny swimmers, jellyfish ( yes, so many you can't see through them, luckily they don't sting, ) other divers churning up the bottom, and just plain gunk in the water. I don't know how to predict most of these, except to say that if you dive a lot, sooner or later you will see some good visibility. Sometimes in the ocean, the visibility will be different in different depth layers. I have seen the viz go from 3 ft on the way down the anchor line to 20 ft on the wreck.
