Ecology & Habitat

Habitat

Mesopelagic zones of tropical and subtropical ocean regions, typically at depths between 200-1000 meters, characterized by low light conditions and cold temperatures

Ecological Role

Plays a critical role in marine food webs as a mid-level predator and prey species, contributing to energy transfer and nutrient cycling in deep ocean ecosystems

Morphology

  • SKIN COAT Silvery-translucent scales with potential bioluminescent photophores for communication and camouflage
  • LIMBS WINGS Small, thin fins with minimal muscular development, optimized for energy-efficient swimming in deep oceanic zones
  • HEAD SENSORY Large, well-developed eyes for detecting bioluminescent signals and prey in low-light environments, specialized lateral line system for detecting water pressure and movement
  • BODY STRUCTURE Elongated, slender body with streamlined profile, approximately 15-20 cm in total length, adapted for efficient deep-sea locomotion
