In the deep waters of Costa Rica you can find Yeti Crabs, crabs that grow their own food. I read this post after another post about economy today and how difficult is for most of the people and it was like those post were linked together. With this economy, crabs are forced to grow their own food to survive. Kiwa hirsuta was the first Yeti crab discovered in 2005. Yeti crabs have hairy claws and are covered with bacteria which is their main source of food. They wave their claws like dancing to farm the bacteria because with this action they provide additional nutrients to bacteria. Usually Yeti crabs are found in areas with methane and hydrogen sulfide because their bacteria grow on those environments.
