Sunflower Seastar Has Weird Way Of Eating

The sunflower seastar (Pycnopodia helianthoides) is a large sea star found in the northeast Pacific. It is the largest sea star in the world, with a maximum armspan of 3.3 ft. A sunflower seastar can have up to 26 arms and 15,000 tube feet, which it can use to pry open a clam. The sunflower seastar then pushes its stomach out of its mouth and into the clam, digesting the hapless bivalve in its own shell.
