How do blue crabs eat their food?
Answer Dear Megan Thank you for your question. I also wish to thank the authors of the websites I used. I am assuming that you want information on adult crabs. http://www.dnr.sc.gov/marine/pub/seascience/bluecrab.html says that blue crabs are opportunistic feeders and have a mixed diet. At high tide, theys may swim into the salt marsh to pluck snails from the tall grass. At times, they burrow into the bottom with only their eye stalks visible, lying in wait for an unsuspecting fish. They may be attracted by the odour or oil produced by oily fishes. They can follow a current upstream by criss-crossing the stream bed. http://www.ehow.com/facts_5489309_do-blue-crabs-eat.html says that the crabs use their claws and legs to search the sea floor for their food. http://www.bluecrab.info/lifecycle.html says that crabs use the tips of their front-most walking legs to probe the bottom for buried bivalves and to manipulate them after they are located. A photo seems to show the crab using its claw
