About Pachycara angeloi

Pachycara angeloi is a species of deep-sea fish in the family Zoarcidae, commonly known as eelpouts. It is found in hydrothermal vent ecosystems, where it thrives in extreme conditions such as high temperatures and low oxygen levels. This species is adapted to the unique chemical environment of hydrothermal vents and plays a role in the ecological dynamics of these habitats by feeding on smaller invertebrates. Its discovery contributes to our understanding of biodiversity and adaptation in deep-sea ecosystems.

Description

The new species is distinguished from its congeners by the following combination of characters: scales and pelvic fins absent; lateral line configuration mediolateral; dorsal fin origin associated with vertebrae 7–9 with no free predorsal pterygiophores; vertebrae 27–28 + 57–59 = 85–87; dorsal-fin rays 78–80, anal-fin rays 58–62; pectoral fin rays 13–15.
