111028 Lost Coast

This beach is relatively untouched by humans and is home to some special organisms.

The team made many new and interesting finds:
IMG_8859s
Strange looking hermit crab.

IMG_8717s
Hidden peacock sole. The outline gave it away.

IMG_8726s
It is quite a gentle fish.

IMG_8727s
A leech on the peacock sole.

IMG_8736s
IMG_8746s
Crinoid. It had only 10 arms, perhaps a juvenile?

IMG_8929s
Batik slug.

IMG_8832s
IMG_8801s
More strange slugs I have not seen before. Hoping Chay Hoon can ID them for us.

IMG_8812s
Healthy population of bonnet snails on this beach.

Spines on the head are very sharp. It is easy to cut oneself on a buried snail while digging in the sand.

IMG_8819s
Buried snail attacking a sand dollar, from underneath.

IMG_8853s
A live button snail. These snails have many appendages and a rather interesting mouth. They can swim by wriggling in the water to escape danger.

IMG_8885s
There were some olive snails.

IMG_8898s
Fig snail as it is found. These snails are not often seen on our shores.

IMG_8948s
IMG_8942s
Full body shots of a couple of fig snails.

IMG_8951s
Sinum moon snail. These snails secrete a lot of slime.

IMG_8934s
Never saw this snail alive before.

IMG_8839s
IMG_8843s
Interesting looking Astropecten. Marcus has a video of it burrowing into the sand quite differently from the smaller and more commonly seen Astropecten sea stars.

IMG_8874s
There were a couple of stranded brittlestars, possibly victims of birds.

IMG_8887s
A small stretch has quite a few of these Laganum sand dollars which seem to be emerging from the sand. They were also all facing the same direction (towards the sea) coming out.

IMG_8927s
Lovenia heart urchin.

IMG_8905s
Smooth sea cucumber.

IMG_8915s
IMG_8922s
No idea what this is, looks like a sea cucumber with sea anemone tentacles.

The white slug is a Philine sp.

The black one is another Philinopsis sp. but not sure if it is a darker version of the batik one above.
