Lophopanopeus

Lophopanopeus is a genus of crabs in the family Xanthidae, commonly known as mud crabs. They are found in the intertidal zones and shallow coastal waters of the western Atlantic Ocean, from Nova Scotia to the Gulf of Mexico. They are known for their distinctive, often brightly colored, shells and for their tendency to burrow in mud or sand.

Common Names

Crabs in this genus are commonly known as mud crabs, but other common names include:

  • Atlantic mud crab
  • Common mud crab
  • Yellow shore crab
  • Marsh crab

Characteristics

Lophopanopeus crabs have a number of distinguishing features, including:

  • A carapace (upper shell) that is typically broad and flattened, with a smooth or slightly granular surface.
  • A pair of prominent, sharp eyes on stalks.
  • A pair of large, powerful chelae (claws).
  • A pair of walking legs on each side of the body.
  • A pair of short, slender swimmerets (abdominal appendages) used for swimming.

The coloration of Lophopanopeus crabs varies depending on the species and the environment, but they are often brightly colored, with hues of yellow, orange, red, and brown.

Environment

Lophopanopeus crabs are typically found in intertidal zones and shallow coastal waters, where they burrow in mud or sand. They are often found in estuaries, salt marshes, and mangrove swamps. They prefer areas with a high abundance of detritus, which provides them with food and shelter.
