Itajobi Blenny

Scartella itajobi

The Itajobi Blenny, a member of the combtooth blenny family, is a small reef fish found in the Atlantic Ocean. It can grow up to 4.7 centimeters in length. This species is distinguished by a small blue spot on the second dorsal spine, particularly noticeable in adult males. Its head is covered with tiny black spots, which sets it apart from similar species like Scartella cristata. The Itajobi Blenny has a fusiform body shape and typically features 12 dorsal spines and 13 to 15 dorsal soft rays. Endemic to the Noronha-Rocas island complex off northeastern Brazil, the Itajobi Blenny inhabits shallow waters and tide pools. It is often found in small crevices of emerged rocks, sometimes remaining out of water for up to 20 minutes, likely as a predator avoidance strategy. This species is highly tolerant of variations in salinity and temperature, making it well-suited to its dynamic environment. The Itajobi Blenny is oviparous, with distinct pairing during the breeding process. Its eggs are demersal and adhere to substrates via a filamentous pad. The larvae are planktonic and are commonly found in shallow, coastal waters. According to the IUCN Red List, the conservation status of the Itajobi Blenny is Least Concern.
