Sea Floater

The Sea Floater is descended from the Hydrogen Jellysquid. It grew a hydrogen sac that is so large, it can pull the animal from the water. The Sea Floater can control how much hydrogen is in the sac using a hole on its forehead. A muscular flap similar to the human glottis keeps hydrogen from escaping. It must stay near the water so it can get its hydrogen. The Sea Floater's tentacles, which were beneath the breathing holes, fused to form an optical tentacle, so it can see its prey and the direction it's squirting the toxin. It's either a predator (eating anything that moves) or a scavenger. To catch their prey, the Sea Floater has developed chromatophores like the celoid cephalopods on Earth. It can create pulsating patterns to attract prey or blend in with the water to avoid predators. The four tentacles that dangled in the water are now ambulatory and have lost the poisonous spines. They can still be placed in the water when hunting. The two tentacles next to its mouth grow longer and likens the appearance to an Earth squid's tentacles. It becomes a manipulator. All of their tentacles have chambers filled with air to help their flotation in the air if they float over the water. Sea Floaters reproduce in the same way as their ancestor.
