Anemone Bubblehorn

The anemone bubblehorn has split from it’s ancestor and returned to the water. It has evolved to feed on microorganisms instead of excrement. It sucks water into it’s mouth and microorganisms get caught in primitive hairs that act as a net. The mouth will then close and the food collected in the hair is swallowed. The bubblehorn will then pause as the sea water is taken round a primitive, intestine like lung used for oxygen uptake. The lung is able to hold a lot of oxygen at a time, allowing the bubblehorn to effectively hold it’s breath. De-oxygenated water is then forced out of the mouth. This makes it look like the bubblehorn is breathing, with an intake, a pause and finally an exhale. This is for both food and respiration.

It’s legs have become bigger and flatter and slowly pulls the bubblehorn along the coast floor. It’s shell still contains the bacteria its ancestors had and would be used in defence, but as of yet it has no predators. The weight of it’s shell means the move very slowly along the sand. It’s antennea now have a stronger sense of ‘smell’. These are now used find partners ready to breed. Hormones are released when a bubblehorn is ready to mate. eggs are laid on rocks on the sea floor. They are attached to the rocks by a sticky ‘glue’ that encapsulates the eggs hardens quickly as an egg that floats would be preyed upon by flying predators.
