Cobblebell
The cobblebell split from its ancestor, the beach grappler, and has evolved by becoming an organism composed of four cells. This has given the cobblebell better durability against the elements and digestive enzymes, twice the feeding capability with its twin probosces, and four times the surface area for photosynthesis.
Unlike its ancestor, the cobblebell feeds off rooted leafstars. This occurred when beach grapplers sometimes ended up inside of damaged rooted leafstars. A majority of them died off inside of the rooted leafstars, but those that did survive, ended up feeding on the cells of the rooted leafstars. They managed to do this because of how rooted leafstar cells are endosymbiotic binucleid cells, which share similarities to cells found in the beachtrops that its ancestor consumed.
Because its current host is much more widespread than the beachtrops are, the cobblebell was able to spread throughout the subtropical and tropical waters between Glicker and Ovi.
Even with all of these adaptations, the cobblebell still depends on saltwater environments to survive and when there is not enough water for them in the beach regions, the cobblebell will go into a state of dormancy until the sands are waterlogged again.
