Beryciformes

Beryciformes is an order of ray-finned fishes. This group is often referred to as the squirrelfish and soldierfish order. It is a large and diverse order, containing over 600 species in more than 70 genera. Beryciformes are found in tropical and temperate waters around the world, inhabiting a wide range of environments from shallow coral reefs to the deep sea.

Morphologically, beryciforms are characterized by certain skeletal features, including a deep body, large eyes, and often a prominent spine in the dorsal fin. Many species possess a characteristic red or pink coloration, which helps them camouflage in the dim light of their preferred habitats. Their diet typically consists of small invertebrates and fish.

The classification of Beryciformes has been a subject of ongoing research, with molecular and morphological studies leading to revisions over time. Historically, it was a broader order, but modern interpretations have led to the removal of some families into other orders. Despite these taxonomic shifts, Beryciformes remains a significant group within the teleost fishes, representing a substantial portion of marine ichthyofauna. Their ecological roles vary greatly depending on the specific species and habitat, contributing to the complex food webs of marine ecosystems.
