Sea stars are often thrown on land after the ocean has discharged water, but they always return. They don’t seem to be able to move at all. It turns out there are hundreds of tubular legs with suction cups at the bottom of these sea creatures. They’re the ones that help animals before they navigate. You can’t see these legs when a starfish is just lying in the sand.
Sea stars are invertebrates similar to needle-skinned animals, and there are about 1600 species. They all have five beams. They literally wrap their stomachs around their victims. In addition, they can easily restore the torn rays. Stellar beast.
The life expectancy of a starfish is twenty years or more.
