The Red-black triplefin (Tripterygion tripteronotum) is a saltwater fish of the family Tripterygiidae that grows up to 8 cm.
Description
The red-black triplefin is a small, blenny-like rock fish of the family Tripterygiidae reaching about 8 cm. It is characterised by the three separate dorsal fins, from which the group takes its name. The species shows a strong colour difference between the sexes: breeding males have a bright red body with a jet-black head, while females and juveniles are inconspicuously brownish and mottled. It lives on shallow, well-lit rocky shores of the Mediterranean and the adjacent eastern Atlantic, often on sunlit rock faces. It hunts small crustaceans and other tiny animals. The male fiercely defends a territory and guards the eggs laid on the rock.
