Ecology & Habitat

Habitat

Deep marine waters, typically between 200-1000 meters depth, inhabiting tropical and subtropical oceanic regions of the world's oceans.

Ecological Role

Plays a critical role in deep-sea food webs as both predator and prey, contributing to energy transfer and marine ecosystem balance.

Morphology

  • SKIN COAT Thin, translucent skin with potential for counter-illumination, helping camouflage against ambient light in deep marine zones.
  • LIMBS WINGS Delicate, transparent fins with minimal muscular development, optimized for energy-efficient vertical migrations.
  • HEAD SENSORY Large, prominent eyes with enhanced light-gathering capabilities, specialized for detecting bioluminescent signals and prey in dark ocean depths.
  • BODY STRUCTURE Slender, elongated body with streamlined profile, approximately 15-20 cm in total length, adapted for efficient swimming in deep-sea environments.
