Crastcumber

The crastcumber replaced its ancestor, the filterfeeding crolandum and has spread to all the temperate and tropical coastlines of Glicker. It has developed a second filter-feeding organ on the opposite side of its body. This allows it to bring in water on one side and spit out water from the other. Both filters can do both so it will suck in water on the side facing the current. It also can "breathe" in CO2 using the same organ. The photosynthetic scales now grow in a symmetrical pattern. They grow on both the korystal and calcrystalium. However, they do better on the calcrystalium when they hang on to the green part of the crystal where predators don't notice them. When low tide comes they shrivel up a bit to where all the plates lock together. This makes it harder for land predators to get to their soft parts. The filtering organ closes up during this time thus they photosynthesize slower than in the water where it could take in more CO2 than the photosynthetic scales can. It reproduces by asexually budding off a new crastcumber from either end of its main body.
