The Crested Triplefin – Trinorfolkia cristata is a small, colorful fish found in the coastal waters of the Indo-Pacific region. This fish, known for its distinct crest, is a fascinating example of the diversity found within the marine environment.
Description & Characteristics
The Trinorfolkia cristata is a relatively small fish, with a maximum size of 5.2 cm. Its body is elongated and compressed, with a prominent crest on its head, giving it its common name. This crest is often a vibrant orange or red, contrasting with the blue and yellow markings found on its body.
Habitat and Occurrence
The Crested Triplefin – Trinorfolkia cristata is found in shallow coastal waters, typically in depths ranging from 0.0 to 15.0 meters. It is particularly common in rocky reefs, tide pools, and coral rubble. This species inhabits the intertidal and neritic zones, meaning it lives in areas that are influenced by the tides and are close to the shore. Its presence in these environments is significant to the overall health of these coastal ecosystems.
Taxonomy
The Trinorfolkia cristata belongs to the family Tripterygiidae, commonly known as triplefins. These fish are classified under the order Blenniiformes, a group that also includes blennies and combtooth blennies. The order Blenniiformes, in turn, falls under the class Teleostei, which encompasses the majority of ray-finned fishes. This intricate classification system reflects the evolutionary relationships and shared characteristics among these diverse fish species.
Feeding
The Crested Triplefin – Trinorfolkia cristata feeds on a diet of zoobenthos and zooplankton, small organisms that inhabit the bottom of the ocean floor and the water column, respectively. This diverse diet contributes to its role in the marine food web, where it helps regulate the populations of these smaller organisms.
