Reteporella grimaldii is a species of bryozoans  in the family Reteporidae.  It is composed of a colony of small animals that form a limestone substrate which takes the form of a refined lace. Hence the name of sea lace. The animals that compose it live on organic particles, plankton, filtering the water carried by the current. The Reteporella can take on different colors based on the species and the environmental conditions in which it lives. We have little information on the environment in which it lives but we can say with certainty, based on our direct experience, that it is possible to meet it from 10 meters up to 100 meters deep. The video we show you was shot in the Mediterranea Sea at 56 meters deep.
