One or better two more questions. First sponge I guess is Petrosia ficiformis but the second? There is one reference I found on the Internet with a very similar image from Turkey stating to be "Ircinia oros": (Link ) (The first two images are rotated by 90 degrees to put them in landscape mode.) Images are from a cave at Cape Greco/Cyprus at about 15m depth.

Salve Thank You again for pointing me in the right direction. Here is one more sponge from Cyprus. This dark black type with "grills" is quite common in Cyprus Marine Waters.
