As a follow-up to yesterday’s Seaweed Dawn post showing Fucus glowing in the yellow light, today’s post shows the very lowest intertidal edge, pictures taken at the lowest tide we experienced during the Kilgii Gwaay archaeology project this year. This post features bat stars and turban snails and a lot of other things that I am not familiar with and have not looked up either. Bat stars come in an incredible variety of colours, but I think are all one species. I am pretty sure these are the Red Turban snails (Lithopoma gibberosa). They are said to be good to eat, though I have not tried them. They have large operculum which is an oval-shaped flat shell disc that is used to close the entrance to the main shell. Turban snail opercula are used as an inlay to decorate Northwest Coast boxes and masks and other wood carvings.
There are also some interesting seaweeds at these lower tidal levels – the kelp fronds are in the lower tidal reaches, the green algae(?) I only noticed at the lowest levels.

Tansy, one of the Quimper Hittys came along and has blogged about the trip from a doll’s view and you can find those posts here while this post has a good shot of a turban snail that gives a sense of scale and this one has some good shots of her inspecting the bat stars.
