Hairy Shore Crab These were by far the most numerous crabs on the beach today. Lift any rock in a wetter area and dozens will scramble for an new crevice. Every once in a while one would get feisty and be photographed :) Geotagged,Hemigrapsus oregonensis,United States Click/tap to enlarge Species introCountry intro

Hairy Shore Crab

  1. Awesome. I wonder why they call it "hairy"? Posted 11 years ago
  2. I gather that the hairs on the legs not present on many crabs. It's got a lot of pseudonyms - it can also be called the Bay Shore Crab, Green Shore Crab, Oregon Shore Crab, Yellow Shore Crab, Mud Flat Crab… I picked Hairy because the other Hemigrapsus that I posted does not have hairs. Since the two are closely related and both can have color variations that make them similar looking, to tell the two apart, the hairs are a better feature to look for. The purple shore crab's unique feature are the red/purple spots on it's claws. Posted 11 years ago
