Ho ricevuto una richiesta, da parte dell'Università di Bologna, che a sua volta l'ha ricevuta da Israele, sulla presenza dell'ascidia  Herdmania momus  nel Mediterraneo. Qualcuno ha informazioni?

Gianni

Ho messo due foto su yahoo nella cartella ascidia.

Queste sono le informazioni che ho:

Herdmania momus

Large solitary ascidian (10 cm), with a rough tunic ofter covered with  epibiotic organisms. Typical the trumpet shape and the colour in white and brown sectors of the siphons.

Distriburion: Indo-Pacific and Western Atlantic.

Ecology: Common along the external reef, often as  epibiotic of other organisms (here a gorgonian), covered in its turn with epibiotic species (here the polychaete worm Filogranella). Common also on shipwrecks

Association: With gorgonians epibiotic species, with many  msessile species covering it (sponges, ascidians, bryozoans, hydroids).

Similar species: The trumpet like shape of siphons is typical, and allows identification from other fouled species like Polycarpa pigmentata.
