I always love to hold and see Star Fish! One day last winter, my sister and I saw hundreds of them at one of our local beaches! It was such an amazing sight. I love how they all are different colors, sizes and even shapes.
Fact #1 Starfish are also known as sea stars and are not really fish despite the name given to them. These are echinoderms, which are found abundant in the deep blue seas and shallow waters as well.
Fact #2 In case a starfish loses its arm, it is capable of regenerating the same!
Fact #3 Starfish are not completely blind, even though they do not have eyes. Starfish sense light and shapes through an eyespot (an organ sensitive to light) located at the tip of their arms.
Fact #4 There are over 2,000 species of starfish.
Fact #5 Starfish are about 5 to 10 inches, and can weigh 11 lbs.
Fact #6 Sea stars belong to the Phylum Echinodermata. That means they are related to sand dollars (yes, they are a real animal), sea urchins, and sea cucumbers.
Fact #7 Depending on the species, a sea star's skin may feel leathery, or slightly prickly. Sea stars have a tough covering on their upper side, which is made up of plates of calcium carbonate with tiny spines on their surface. A sea star's spines are used for protection from predators, which include birds, fish and sea otters.
Fact #8 They have bony, calcified skin, which protects them from most predators, and many wear striking colors that camouflage them or scare off potential attackers. Purely marine animals, there are no freshwater sea stars, and only a few live in brackish water.
Fact #9 Not all sea stars have 5 arms! While the five armed variety are the most well known, not all sea stars have five arms. Some have many more. Take the sun star for instance, which has up to 40 arms!
Fact #10 Starfish normally live up to 35 years in the wild. Wow!
