During a scuba dive I encountered this Catshark egg attached to an abandoned anchor rope on the seabed. The Catshark is a predominantly nocturnal fish that hides in the burrows and ravines of submerged cliffs during the day. Typically this small shark fixes its eggs to the various Gorgonians to make the most of the sea currents. In this case, as there were no Gorgonians in the seabed, he used the rope abandoned on the bottom by a boat.

Tedania anhelans is a sea sponge that has an arborescent shape with colors that vary from transparent to light gray or dark gray depending on the conditions and depths of the environment in which it lives and personally I also add based on age: more pale in the juvenile phase or darker in the mature phase. It is present throughout the Mediterranean Sea at a depth ranging from 10 to over 100 meters on hard substrates, in rocky walls but also, as in our case, on Gorgonians and fishing nets abandoned for several years. In fact, the Tedania sponge reproduces very easily.
