Abronicidae

Abronicidae is a family of deep-sea crustaceans belonging to the order Decapoda. They are commonly known as squat lobsters or squat shrimps and are characterized by their short, broad bodies and stout, spiny legs.

Common Names

Members of the Abronicidae family are commonly referred to as squat lobsters or squat shrimps. These names are derived from their flattened, squat appearance.

Characteristics

Abronicidae species possess several distinctive characteristics that differentiate them from other decapod crustaceans:

  • Short, broad carapace: Their carapace is significantly wider than it is long, giving them a squat appearance.
  • Stout, spiny legs: Their legs are robust and often have prominent spines, particularly on the chelipeds (claws).
  • Reduced rostrum: The rostrum, a projection on the head, is generally small or absent in abronicids.
  • Abdomen: Their abdomen is usually curled underneath the carapace.
  • Size: Abronicidae species typically range in size from a few centimeters to around 10 cm in length.

Environment

Abronicidae species are found in deep-sea environments, typically at depths greater than 200 meters. They are often associated with benthic habitats, such as seamounts, hydrothermal vents, and cold seeps. They are known to be scavengers and predators, feeding on a variety of organisms, including worms, small crustaceans, and mollusks.
