The Northern Kelp Crab (Pugettia producta) is a common sight for divers exploring kelp forests and rocky reefs along the Pacific coast. Typically reaching around 6cm, but occasionally growing up to 9cm, these crustaceans blend seamlessly with their surroundings. While they might not be the most charismatic megafauna, their presence is a reassuring sign of a healthy ecosystem. Keep an eye out for them clinging to kelp fronds or nestled amongst the rocks as you explore the benthic zone down to depths of 75m. Despite their abundance, they are surprisingly adept at camouflaging, so a keen eye is needed to spot them!
Distinguishing the Northern Kelp Crab involves noting a few key features. Look for a smooth, oval-shaped carapace, often reddish-brown or greenish-brown, providing excellent camouflage amongst kelp. The carapace is noticeably wider at the front. They have relatively small claws compared to other crab species, and their legs are adapted for clinging rather than scuttling quickly. Their coloration can vary depending on their diet and environment, so look for the overall shape and smooth shell rather than relying solely on color.
