We saw a mother cuttlefish looking after a baby cuttlefish. A hermit crab with a very interesting shell. An tiny octopus that could camouflage itself, but would turn red when it moves. He buried himself in the sand once he got worried so Chrissy and I helped him by throwing more sand on him. There was also an enormous Eastern Rock Lobster. Chrissy also showed me that when you wave your hand, little lights appear. There were long tentacle things that seemed kind of creepy -- they were echiurans -- a type of worm. There was a sea slug.
We saw most of the stuff on this page:
