Clypeaster australasiae sea urchin or some kind of star!!!

Clypeaster australasiae is a species of sea urchin also known as the UFO star or a cake urchin. It has a round body with a flower shape on the top has its mouth at the base center. This creature’s body is completely covered with small spine armor

This little creature is found all over the world. UFO Star has a very different lifestyle compared to other urchins that they hunt for food night and bury themselves in sand in day light. This is the reason that we don’t see them close in person near the beaches too often, they just hide themselves. We just add a small time lapse video for Clypeaster going inside the substrate have a look;

They are definitely bottom creatures and when they move inside the sand then tend to carry everything that gets stuck to its spine. In an aquarium with good substrate one would find small little things moving from one place to other.

It’s such a pretty little creature that in large system with good amount of substrate one would hardy notice them. So it’s like, if you have the urge to add a live creature in the tank, this little creature is pretty good for that.


Like always it's my day one in the hobby. Always been a hobbyist but never knew would dive so deep in the hobby. I too started with a freshwater aquarium. When I first started saltwater aquarium it just grew on me and I knew that had to do more in this hobby. I am a Post-Grad in Business Administration have worked with Coldstar Logistics, Amazon and Jindal's before jumping completely in the ocean. Other than aquarium hobby I have my interests in travel, digital games and consumer web technology.
