Field Notes

Description:

A white skeleton washed ashore.
It has a roundish pentagon shape with a irregular rectangle hole in the middle.
There are a lot of print patterns on it - lines, dots, stripes.
I am sure that this is a skeleton of a marine animal.
A type of Sand Dollar.

Habitat:

Sea floor (maybe near the coast) of South China Sea.

Notes:

My first Noah spotting of a marine organism.
I found it on the sandy beach of Mimpian Jadi Resort during an early morning walk there with my family.
We have chosen to walk there early in the morning because that is when the sea is in it's low tide and we can walk further away to find marine things that are left behind by the waves.

Definitely a sand dollar. They are a kind of flattened sea urchin, and are covered with "velvet" when alive. There are a number of species of them, and this one is not the exact same species that occurs on the Oregon coast, though it's similar. The "dollar" name comes from its size and shape, though they usually grow past the size of an American silver dollar. The sand dollars always have a five-fold symmetry, but I don't think that the fact that a dollar is a multiple of 5 ever entered into its naming.

I agree, it looks like a Sand Dollar.

Thanks S Frazier. Funny name for a sea creature but it suits.
