Alticus monochrus, commonly known as the “Black Blenny,” is a small species of fish belonging to the Blenniidae family. They are fascinating creatures that exhibit unique adaptations for life in the intertidal zone. This description will delve into the characteristics, habitat, taxonomy, and feeding habits of Alticus monochrus.
Description & Characteristics
Alticus monochrus, also known as the Black Blenny, is a relatively small fish, reaching a maximum size of 10.0 cm. They are distinguished by their black or dark brown coloration, sometimes with subtle lighter markings, making them well-camouflaged against the rocky intertidal environment they call home.
Habitat and Occurrence
Alticus monochrus is found in the intertidal zone of rocky shores, particularly in areas with a good supply of algae. They are commonly observed in the splash zone, the area that is intermittently submerged and exposed by the tides. This species is often found in the tropical and subtropical regions of the Indo-Pacific, including the Red Sea, the Indian Ocean, and the western Pacific Ocean. Their occurrence in these regions is directly linked to the presence of suitable rocky intertidal habitats.
Taxonomy
Alticus monochrus is a member of the Class: Teleostei, which comprises most of the bony fish species. It further belongs to the Order: Blenniiformes, which includes the blennies, combtooth blennies, and triplefins. Finally, it is classified under the Family: Blenniidae, a family of fish that are typically small and have elongated bodies, making them easily recognizable.
Feeding
Alticus monochrus are primarily herbivorous, feeding mainly on algae that grow on the rocks in the intertidal zone. They use their specialized teeth to scrape algae off the rocks and consume them. Their diet can also include small invertebrates like crustaceans, which they may scavenge or hunt for.
