Sunday Evening Art Gallery–Starfish

Despite their name, Starfish (sea stars) aren’t fish.

Australian Southern Sand Star

Since they don’t have a backbone, starfish belong to a group of species called invertebrates, which also includes urchins and sponges.

Basket Starfish

Typically, starfish have five arms, but some sea stars may have more limbs.

Giant Spined Star

Sea stars move using their tube feet and have an advanced water vascular system that they use to fill up their feet with sea water.

Chocolate Chip Sea Star

They do not have blood but instead take in seawater through the sieve plate, or madreporite, located on top of the sea star, and use that to fill up their feet.

Morning Sun Starfish

Starfish are equipped with hundreds of tiny little feet at the underside and end of each of their arms.

Royal Starfish

To move from one place to another, seawater is filled into its tube feet, causing the arm to move just like a foot would.

Sunflower Star

When some species of starfish find a tasty snack, such as a mussel or an oyster, they extend their stomach out of their mouth to digest the soft parts of their prey.

Pincushion Starfish

This creates a soup-like substance that they then slurp back into their body to finish off the feast.

Antarctic Sun Starfish

Starfish can retract their feet using muscles or use them as suction to hold onto a substrate or its prey.

Crown of Thorns Starfish

The starfish is a fascinating and unique form of life that brings wonder and fascination to anyone falling under their spell.

Brisingid Sea Star

Nature is no doubt an amazing artist.
