Hello,
as we are carrying visual census surveys assesing the biodiversity of fish,
algae and invertebrates in the shallow littoral zone of the eastern Aegean
Sea, Greece, I wanted to ask for some advise on any identification key for
tunicates you would consider useful. We would be interested for both
taxonomic guides, as well as photographic guides.
Also, please let me know if any of you would be interested in recieving
photographs of tunicates for identification, of any species we will not be
able to identify here,
thank you,
Anastasia
