Ecology & Habitat

Habitat

Deep marine environments, typically found in continental shelf and slope regions at depths between 200-1,000 meters, preferring cold temperate waters with rocky or sandy substrates.

Ecological Role

Plays a crucial role in deep-sea ecosystem dynamics as a mid-level predator, contributing to marine food web regulation and biodiversity maintenance.

Morphology

  • SKIN COAT Smooth, gelatinous skin with minimal scaling, adapted for low-light deep marine conditions
  • LIMBS WINGS Possesses large pectoral fins for maneuvering, single dorsal fin with potential defensive spine, streamlined for deep-sea locomotion
  • HEAD SENSORY Large electroreceptive sensory system with specialized ampullae of Lorenzini for detecting prey and navigating dark marine environments
  • BODY STRUCTURE Elongated, torpedo-shaped body with cartilaginous skeleton, typically 50-80 cm in total length, possessing a distinctive chimaera body plan with reduced scales
