The Impact of Ocean Plastic | Sea Stars
Because they’re so placid and calming to watch, we tend to think of sea stars as the ocean’s decorations, but these incredible invertebrates are actually one of the ocean’s more bizarre residents. Here are just a few reasons to love these freakishly beautiful creatures.
1. There are around 2,000 species of sea stars in the ocean. Some have as many as 40 arms. Each arm is equipped with a single eyespot on the tip and up to 15,000 tiny tube feet.
2. Many sea stars are considered keystone species because their voracious eating habits help maintain a balanced ecosystem. They help control the populations of other species that have the potential to become destructive if they grow too large.
3. Sea stars can regenerate severed or damaged limbs. In some cases, a severed limb can even regenerate a whole new sea star! This regeneration process can take up to a year.
4. Many sea star species have a cardiac stomach that can extend from their mouth and digest prey outside of their bodies.
5. Sea stars have no brain and no blood. They use filtered seawater to pump nutrients through their nervous system, which acts like their brain.
