Today we learn more about the curious life style of bryozoans from Dr Dennis P. Gordon on Day 2 of the Bryozoans and Hydroids Workshop.
Bryozoans are zombies! The feeding zooid has tentacles as well a
stomach to digest food. Nutrients it obtains are passed on to other kinds of
non-feeding zooids in the colony. What is amazing in bryozoans,
the feeding zooid will die after a few weeks usually because its stomach is
all gunked up. After which a new feeding zooid grows within the same
container. This can happen once or 4-5 times.

Earlier on, thanks to Cai Yixiong for lugging up my cooler full of bryozoans and hydroids from Changi!
glassy branching bryozoan that I found at Changi earlier today. There are all kinds of other animals on it. It's hard to tell which tentacled animal is the bryozoan and which are hydroids or other beasties.
Chay Hoon took of the nudibranchs that live on these bryozoans! We saw these at Punggol but I was too lame to photograph these super tiny creatures.
