Sea Stars

Sea stars (also known as starfish) are spiny, hard-skinned animals that live on the rocky sea floor. These invertebrates are NOT fish; they are echinoderms. Sea stars move very slowly along the sea bed, using hundreds of tiny tube feet. There are over 2,000 different species of sea stars worldwide. Sea stars are carnivores (meat-eaters). They eat clams, oysters, coral, fish, and other animals. They push their stomach out through their mouth (located on the underside of the sea star) and digest the prey.
Most sea stars have five arms (or a multiple of five) that radiate from a central disk. Sea stars do not have a brain; they have a simple ring of nerve cells that moves information around the body. Eyespots (primitive light sensors) are at the tip of each arm. If a sea star's arm is cut off, it will regenerate (regrow).

Classification: Kingdom Animalia (animals), Phylum Echinodermata (echinoderms), Class Asteroidea (sea stars), about 2,000 species.

Hello Evelynn, love these Starfish you give to us and they look quite big. You have posted a very good selection of "sea things" or Echinoderms. The light in these shots looks a little harsh to me, maybe taken during midday? I wonder would fill flash or maybe a diffuser help to soften the shadows. I believe you are getting a DSLR, and some new lens (good selection) I am sure you will love your new equipment. Id say you will be very good to. Regards Steve.

nice colours, light, POV, DOF, details and composition!
Thanks Ana:)

I like the rocky arch with the water rippling around it. Nice color and lighting, well done.
