Starfish are pretty cool—at least in the oceanic sphere. They’re hearty and tough, and at times, they’re also odd. They’re the only animals in the ocean that eat their own kind, which makes sense—if you’re an animal that eats other animals, you’re going to have a lot of competition for food. Furthermore, at least some species of starfish have the ability to detach their arms and move them independently, which is pretty impressive for something that’s only a few millimeters in size.
Starfishes, like many other marine animals, often depend on eating their prey whole, or at least partially. This is because they don’t have teeth, which means they have to use their jaws to crush their food. (As a result, starfishes can get their food stuck in their throats if they don’t use their tentacles to bring it in.)
The majority of starfish feed on plankton in the water, but others are carnivores, like the ones that live in the deep sea. These carnivorous starfish have a special mechanism for catching prey when it comes to food. They have a long, flexible tube that expands like a straw and can extend for as long as 100 millimeters into the water column, where they catch plankton. So their prey is trapped in a “pincer” and then the starfish engulfs them.. Read more about how do most starfish get their food filter feeding and let us know what you think.
The sea star pulls its stomach out of its body and into the bivalve when the prey is opened, secreting enzymes that breakdown the prey’s soft body tissues. The bivalve is subsequently liquefied and absorbed into the stomach. Sea stars eat often, and their size is determined by the quantity of food they consume rather than their age.
What’s more, where does Starfish obtain its food?
Clams, oysters, sand dollars, and mussels are their primary food sources, and they are typically stuck to rocks or otherwise unable to flee fast. When they can locate them, they also consume snails and wounded fish. However, not all starfish search for food. Starfish are strong hunters that eat mostly mollusks.
Also, how do starfish get rid of their energy? When water diffuses into the tube feet of a starfish, it is called diffusion. This happens when you breathe via your lungs rather than through your water vascular system. The Starfish obtains its energy via the water vascular system.
So, what should I feed a starfish?
They are grazers, which means they consume anything that has dropped to the bottom of your tank, such as fish flakes, pellets, and any other food. Most species like a meaty diet of mollusks, so adding a few clams or mussels to your tank will ensure their happiness.
What is it that eats sea stars?
Fish, sea turtles, snails, crabs, shrimp, otters, birds, and even other sea stars are all known to consume sea stars. Even though the sea star’s skin is rough and bumpy, a predator with a big enough mouth can devour it whole. Predators with smaller jaws may turn these stars over to consume the softer side.

If you pull a starfish out of the sea, will it die?
No. The starfish would not perish if it were to be out of the water for the time it takes to snap a few photos. During low tide, you’ll frequently find them affixed to rocks and pilings, and they’ll stay out of the water for far longer than it takes to snap a few photos. They can’t, however, remain out of the water forever.
