Common Names

Dairidae crabs are commonly referred to as "spider crabs" due to their long, spindly legs. They are also sometimes called "deep-sea spider crabs" or "Dairid spider crabs."

Characteristics

Dairidae crabs share several key characteristics, including:

  • Long, slender legs that are often covered in spines or hairs.
  • Small, flattened bodies with a narrow carapace.
  • Eyes that are located on stalks.
  • Chelae (claws) that are often relatively small compared to their legs.

Environment

Dairidae crabs are exclusively found in the deep sea, typically at depths between 100 and 3,000 meters. They inhabit a variety of environments, including the continental slope, abyssal plains, and seamounts. Their long legs allow them to move across the seafloor and capture prey.
