Found this in a friends tank. Tried searching, but without a good starting point its hard for me to identify it. Sorry for the poor picture and child-like drawing. Its about 1 centimeter tall. It opens within seconds to what appears to be a jaw with teeth. But as you see, it only opens partially unlike a clam, oyster, etc. The lower part is concave, this also acts as part of the hinge. As it opens this area becomes more concave. Above and along the edge appear to be thick short white whisker like attachments. If disturbed by a brush or sudden light, it closes its "mouth". At the same time it closes against the rock face. The "shell" is very clean. But we have not tried to see if its soft or hard material. Any help is appreciated!
Next time I visit, and assuming it has not moved, I will use my 100mm macro lens to get a better picture (used iPhone with zoom this time).
Any help appreciated!
