Macrorhynchia

Macrorhynchia is a genus of deep-sea squat lobsters in the family Chirostylidae, known for their distinctive elongated, claw-like appendages. They are found in the Indo-Pacific region, with some species inhabiting the Atlantic Ocean. While relatively little is known about their biology, they play an important role in the deep-sea ecosystem, likely acting as scavengers and predators.

Common Names

Common names for Macrorhynchia species include:

  • Long-clawed squat lobster
  • Deep-sea lobster
  • Chirostylid lobster

Characteristics

Macrorhynchia species are characterized by:

  • Elongated, claw-like appendages: Their most striking feature is their disproportionately long, slender claws, which are often longer than their body length.
  • Small, compressed bodies: Their bodies are typically small and compressed, with a flattened carapace and a short abdomen.
  • Large, prominent eyes: Their eyes are large and prominent, likely an adaptation to their deep-sea habitat.
  • Thickened exoskeleton: Their exoskeletons are thickened, providing protection in the deep-sea environment.

Environment

Macrorhynchia species are found in the deep-sea, typically at depths of 200-1000 meters. They inhabit a variety of habitats, including:

  • Seamounts: These underwater mountains provide a unique habitat for deep-sea organisms.
  • Continental slopes: The steep slopes bordering continents are rich in biodiversity.
  • Abyssal plains: These flat, deep-sea environments are home to a variety of specialized organisms.
