It was this afternoon when we spotted a small bluish object on a sandy beach. To me, it looked like some fibrous material a.k.a rubbish that was washed up by the high tide. Someone said to me that it isn't a piece of rubbish. And yes indeed. When I picked it up, the center of this object felt spongy. It felt like something which was alive much earlier. And when I looked around the beach, there were more of it were scattered all over the beach located on the North West of Langkawi.
The bluish colour were running out of the object. Like a blue dye coming out when touches the water. Do you notice that on the above picture?

The object above the center is the other side of this weird creature
The weird marine creature next to a set of sand balls made by sand crabs
A close up. This piece is almost the size of RM0.50 coin
Just when all of them were blue and out-of-the blue, I spotted a Yellow one! There was only one yellow we seen on that beach
What are they? They are not sea urchins, for sure. A few guesses came into my mind. Are they some sort of sand dollars or heart urchins? Or possibly they are some sort of echinoderms. Have anyone seen this species? Or could help to identify, please put your comments below. Thank you!
