Deep-Sea Yeti Crab Farms Food on Its Arms

A new crab was discovered in 2006 that farms food on its arms. It grows bacteria, or rather helps them grow by waving its arms over methane vents on the seafloor. This action provides bacteria with the nutrients to grow, and after they grow the crabs eat them. This is a new discovery where an animal provides bacteria growth tools and literally farms its own food. This would be an interesting animal to present to a class to provide the students with new discoveries. This is important for a classroom because students, or at least I, thought that all the discoveries were basically made in the animal world. Technology changes have improved a lot for discovering every corner of the planet, but discoveries like this may not introduce new animals, but they show different behaviors. Differing behaviors are just as exciting to me, they show a change in animal behavior or an improvement and this shows evolution. Micro evolution is greatly exciting to me and I love hearing about articles like this.
