Stenorhynchus
Stenorhynchus is a genus of crabs in the family Majidae, commonly known as “spider crabs.” These crabs are characterized by their long, spidery legs and often have a distinctive, spiny carapace. They are found in a variety of marine environments, including rocky shores, coral reefs, and seagrass beds.
Characteristics
Members of the genus Stenorhynchus typically have a carapace that is wider than it is long, with a distinct rostrum, or beak-like projection, on the front. Their legs are very long and slender, with numerous spines or tubercles. The coloration of these crabs can vary depending on the species and their environment, but they are often brown, orange, or reddish-brown. Some species are also known to be bioluminescent.
Environments
Stenorhynchus crabs are found in a wide range of marine environments, from shallow coastal waters to deeper depths. They prefer habitats with abundant food sources and hiding places, such as rocky shores, coral reefs, seagrass beds, and kelp forests. Some species are also found in the intertidal zone, where they may be exposed to air during low tide.
Common Names
Stenorhynchus crabs are commonly known as "spider crabs" due to their long, spidery legs. Some species may also have specific common names, such as the "long-legged spider crab" (Stenorhynchus seticornis).
