Glass Tulip Worms
Water Tunicates
Believe it or not, these things that look like glass tulips are actually animals. Found in the murky waters of Antarctica, these curious animals are called tunicates.
The plankton-eating tunicates grow up to 3.2 feet (1 meter) long, and filter food by pumping it through an internal mesh structure. The stalk is supported by pressure created by their pump, according to the scientists.
