Order Berycomorphi refers to a group of deep-sea fish with large eyes and elongated bodies. Some synonyms for this order include the deep-sea beryciforms, berycids, and squirrelfishes. These fish are typically found in waters ranging from 500m to 2000m deep and are also characterized by their bright coloration, which is believed to play a role in communication and mate recognition. The Berycomorphi order includes many different families, such as the slimeheads (Trachichthyidae), flagtails (Kuhliidae), and lanternfishes (Myctophidae). Despite their intimidating appearance, Berycomorphi fish are an important part of the ocean ecosystem and provide an abundant source of food for larger predators.
