Coquina Hydroid Lovenella gracilis

They are colonial animals that form erect colonies, on hard surfaces using a hydrorhiza, stem-like structure. They have a symbiotic relationship with Donax clams. The clam provides a substrate for the L. gracilis to attach to while the hydroid protects the clam from predators using its nematocysts. Found in the western Atlantic Ocean.
