Alticus aldabrensis is a species of fish belonging to the family Blenniidae, commonly known as combtooth blennies. These fish are distinguished by their elongated, slender bodies and prominent comb-like teeth.
Description & Characteristics
Alticus aldabrensis, like other combtooth blennies, possesses a characteristic elongated body shape. They are typically small in size, with a maximum length of around 5 cm. Their bodies are generally brown or greyish, with some individuals displaying darker markings. They also have large, protruding eyes, a feature common to many blennies, which helps them to detect potential prey and predators.
Habitat and Occurrence
Alticus aldabrensis is primarily found in the intertidal zone of the Indian Ocean, specifically in the Aldabra Atoll, which lends the species its name. These fish are well-adapted to the harsh conditions of the intertidal zone, where they encounter frequent changes in water levels and salinity. They can be observed clinging to rocks and algae, using their powerful pectoral fins for support and movement. Their habitat is characterized by exposed, rocky shores, often covered in algae and barnacles, making it a typical rocky intertidal environment.
Taxonomy
Alticus aldabrensis belongs to the family Blenniidae, commonly referred to as combtooth blennies. These fish are part of the order Blenniiformes, a diverse group of mostly marine fish, and fall under the class Teleostei, which encompasses the majority of bony fish species. This classification reflects the evolutionary history and shared characteristics of Alticus aldabrensis with other members of its family, order, and class.
Feeding
Alticus aldabrensis is an opportunistic carnivore, consuming a variety of small invertebrates found in its intertidal habitat. Its diet primarily consists of crustaceans, such as amphipods and isopods, as well as algae. Their strong teeth, which are designed for scraping and crushing, aid them in effectively consuming these food sources.
