Overview

Frilled sharks are deepwater specialists with an unmistakably old-looking silhouette: long body, wide mouth, and ruffled gills. They are among the least likely sharks to be seen alive by ordinary coastal observers. Frilled sharks look eel-like, with a long body, terminal mouth, many tricuspid teeth, and the first gill slits forming a frilled collar behind the head. Frilled sharks have patchy records in the Atlantic, Indian, and Pacific oceans, usually tied to deep continental slope and seamount environments. Some species appear to have more restricted regional distributions than the family as a whole.

They occupy deepwater habitats from outer shelf breaks to continental slopes and rises, rarely entering shallow coastal settings.

Added from the World Register of Marine Species (WoRMS).

Why it matters: The frilled gill openings give this ancient-looking shark one of the most unusual head profiles in the group.

Why it is notable

Public encounters are exceptionally rare. Most records come from deepwater captures or specimens brought up from depth.

Species-level taxonomy was verified from Sharkipedia's current species list and taxonomy workbook. In this pass, the narrative fields are cautious family-level placeholders synthesized from broad shark references, chiefly the FAO Sharks of the World catalogue, because a stronger multi-source species-level synthesis was not assembled here without risking invented detail. Replace this with a direct species-level synthesis before publication in the app.
