Hi,

I attach an underwater picture of a colony of freshwater bryozoans. I identified it as Cristatella mucedo. I took the picture in a small natural lake in Northern Italy, in the Province of Bolzano / Bozen.

Please could you confirm my identification?

I tried to fix a colony of this species in ethylic alcohol 70 % and another colony in formalin 10%, but they both fell apart. Could you advise me on the right method for fixing a specimen for the museum's zoological collection?

Thank you in advance for your help.

Sincerely,

Massimo
