Ecology & Habitat

Habitat

Deep marine environments, typically inhabiting continental shelves and upper continental slope regions at depths between 100-800 meters, predominantly in temperate and subtropical oceanic zones.

Ecological Role

Plays a critical role in deep-sea ecosystem food webs as a mid-level predator, contributing to marine biodiversity and serving as an indicator species for oceanic environmental health.

Morphology

  • SKIN COAT Smooth, scale-less skin with a mucus layer providing hydrodynamic efficiency and protection against marine pathogens
  • LIMBS WINGS Possesses distinctive wing-like pectoral fins and a heterocercal tail, enabling precise maneuverability in deep marine habitats
  • HEAD SENSORY Highly developed electroreceptive sensory system with ampullae of Lorenzini, enabling precise prey detection in low-light marine environments
  • BODY STRUCTURE Elongated cartilaginous body with a flattened head, typically measuring 50-80 cm in total length, featuring a robust skeletal structure adapted to deep-sea pressures
