Our Necklace Sea Star will add a colorful splash to your sea-life diorama or school project. You'll find it useful for undersea dioramas, school projects, toys, novelties, animal collections, party favors and more. Our plastic sea star is for decoration or play only. It does not float, and should NOT be put in your aquarium. However, you can make an awesome sea-life or aquarium shoebox diorama using this and other plastic aquatic creatures and mammals, sharks, fish, sea turtles, birds, and decor from our gift shop. There is no mess, no feeding, and no tank cleaning :) The underside of our 2 1/4-inch plastic sea star is white and has grooves and canals like a real starfish. It's name is printed on the underside. Come see our wonderful assortment of sea star toys and gifts.


There are currently about 1,800 varieties of starfish (also known as sea stars). All are echinoderms of the class Asteroidea, and live throughout the world's oceans, at all depths and all temperatures. While most starfish have five arms, creating a typical star-shape, many can have 10-50 arms. Even in species known to typically have five arms, individuals can develop "extras" due to abnormalities during their developmental or larvae stage. Some starfish can regenerate lost arms, and a very few, like the linckia star, can regenerate an entire starfish from a single living arm.
