description Frilled Shark Overview
The frilled shark (Chlamydoselachus anguineus) is a rare deep-sea fish belonging to a remarkably ancient lineage of sharks. Its unique appearance—characterized by an eel-like body and distinctive frilled gill slits—makes it one of the most primitive extant shark species. Scientists study this animal to understand early vertebrate evolution and the adaptations required for survival in extreme, dark ocean environments. It is primarily of interest to marine biologists and ichthyologists.
insights Ranking position
Frilled Shark ranks #1 of 157 in the Deep Sea Fish ranking, ahead of Goblin Shark.
help Frilled Shark FAQ
Where does this shark normally live?
It is a deep-sea species often found in continental slope waters, generally in dim and cold environments. That habitat explains why encounters are limited and mostly from scientific or deep fisheries observations.
What are its most obvious field-identification features?
The species has distinctive frilled gill slits and elongated body proportions with a retro-looking outline. Its shape and movement can look primitive compared with more modern shark forms.
How do museums and documentaries handle the species?
Frilled shark specimens are more often discussed in exhibits on ancient lineages and evolutionary history than seen as frequent live-shows species. The educational value is tied to morphology and phylogenetic context.
