Aqajaq • Seastar

Seastars are invertebrate animals, belonging to the phylum Echinodermata, along with sea urchins, sand dollars, and sea cucumbers. Seastars typically have five arms, although some species have many more. The undersides of their arms are covered with hundreds of "tube feet," which they use to move and also to handle their prey.
