The Mediterranean Mystery blenny (Parablennius incognitus) is a sea fish belonging to the Blenniidae family.
Distribution and habitat
It is an endemic species of the Mediterranean Sea. Its presence in the Black Sea is to be ascertained.
It lives in very shallow waters, often in areas exposed to the fury of the waves, on rocky surfaces rich in vegetation.
Similar to Parablennius zvonimiri. The supraorbital tentacles are made up of a longer front strand from whose back 4 or 5 ramifications branch off; these tentacles are much longer in the male. The nasal tentacle (only on the anterior nostril) has two filaments. For the rest a typical blennide, the dorsal fin has a modest central indentation.
The livery, although variable as in almost all the blennidi has some specific characteristics:
dark spots in the shape of hourglasses edged with blue lines on the sides
a dark oblique stripe on the cheek above which there is a lighter one.
Males in love have bright, yellow or orange colors.
Similar to the other blennids the male treats the eggs that are laid in a den.
Above all based on Crustaceans, mainly Cirripeds.
