(Metzelaar, 1919) |
The Barnacle blenny, Acanthemblemaria spinosa,
also known as the tube blenny or Spinyhead blenny,
is a member of the
blenny family native to the Pacific ocean. It has a mottled black, white and red
coloration over the entire body, which is rather elongated.
As with most blennies, the head of this animal has small
hair-like appendages over the eyes, which are large and red.
It ranges in size from .75 inches to 1.5 inches in length.
A. spinosa prefers to inhabit the empty shells of
barnacles, hence their name, but will also live in rock
and
coral crevices. They are opportunistic feeders,
preferring to quickly dart out and retrieve food bits from
the water column, as opposed to engaging in active foraging
and hunting behavior. They eat small crustaceans and other
plankton.
In the home
aquarium, they are entertaining and only require
moderate care. They are
reef safe.
