Ecology & Habitat

Habitat

Deep marine environments, typically inhabiting continental slopes and oceanic depths between 500-1500 meters, with preference for cold, dark submarine ecosystems

Ecological Role

Plays a critical role in deep-sea food webs as a predatory species, contributing to marine ecosystem balance and biodiversity in submarine environments

Morphology

  • SKIN COAT Smooth, scaleless dermis with cartilaginous dermal denticles providing hydrodynamic efficiency
  • LIMBS WINGS Presence of pectoral fins with characteristic chimaera wing-like configuration, enabling precise maneuverability in deep marine environments
  • HEAD SENSORY Highly developed electrosensory organs (ampullae of Lorenzini), enabling precise prey detection in low-visibility deep-sea conditions
  • BODY STRUCTURE Elongated cartilaginous body, approximately 1-1.5 meters in total length, with a distinctive chimaera body plan featuring a large head and tapering posterior
