Ecology & Habitat

Habitat

Deep marine environments, likely prehistoric oceanic regions with complex geological formations, typically associated with continental shelf and upper bathyal zones around 100-500 meters depth.

Ecological Role

Likely played a significant role in marine trophic networks as a mid-level predator, contributing to oceanic ecosystem balance and marine biodiversity during its evolutionary period.

Morphology

  • SKIN COAT Smooth cartilaginous external covering with potential dermal denticle structures
  • LIMBS WINGS Likely possessing specialized pectoral and pelvic fins for precise underwater navigation
  • HEAD SENSORY Probable advanced sensory capabilities including electrosensory and chemosensory systems typical of chimaera species
  • BODY STRUCTURE Elongated cartilaginous body, characteristic of early Holocephalan fish, with streamlined form adapted for efficient marine locomotion
