Odax cyanoallix
Odax cyanoallix is a marine fish with bright blue pectoral fins in males. It lives near the rocky shores of New Zealand and feeds on algae.
Odax cyanoallix differs from related species by the bright blue pectoral fins of males. This fish is important for nature because it controls the growth of algae on coastal rocks.
