    hi Sara,

    ive often wanted to find out the purpose of the feeler like appendatures above a lawnmower bleenie's eyes. I got a decent pic of one finally and thought you might know. I assume its for sensing currents and or movement of other fish (predators?) in the blennies area, but do you know what they are actually called and what they are for?

    They're called Cirii and they use it to sense the environment around them

    Hi, I'm so sorry I didn't see this til now... this is a great question. Unfortunately, I'm not much of a "fish expert"... but I will try my best to find out for you.

    I'm still looking/reading...

    But I asked BobF... he says they're used to help the fish "feel around"... and possibly also for identification purposes (so the fish can ID each other).

    id love a detailed answer if you manage to get one.

    the section of id for the fish to know who's who took me back years to an individual lecture by my entomology lecturer who was the leading expert in dung beetles. he gave possible the most sidesplitting 3 hour lecture on the mating rituals of some dung beetles, including knobs and bumps on the thorax and head which the male dung beetle feels for id purposes so as to not cross breed. Never before had a dung beetle been so interesting :)

    Fascinating, isn't it? Maybe these things also serve a purpose in mating... there's no "rule" that says the can only serve one purpose.
