Starfish Facts on How They Protect Themselves

When a prey is being stalked by predators, the first reaction of the prey is always to flee the scene. It will only be during compromising situations wherein the prey would start to be in fight mode. Unfortunately, starfishes cannot just escape from predators because most of them are generally slow. So they use numerous other defense mechanisms to protect themselves.

According to the starfish facts gathered by zoologists, certain species of starfishes have a chemical coating in their bodies called saponin. Saponin is a chemical that gives the starfish a very unpleasant taste. So as soon as the predator tries to take a bite of the starfish, they can spit the starfish out because of its bitterness. For some species of starfishes, they even have poisons in their outer body walls. There is also a specific kind of starfish that can produce mucus in their skin when they are threatened.

The spines on the back of the starfishes are not just for beautification purposes. These spines can be very sharp which can intimidate and eventually scare the possible predators that will spot the starfishes. In addition to that, the spines also make these starfishes look like rocks instead of living organisms and they help greatly in blending with the background.

Regeneration and Self Cloning

In general, starfish regenerate by way of a three-stage process. Firstly, the repair stage heals the creature’s exposed wound. This phase is followed by the regenerative stage, in which the body of the echinoderm produces new cells and begins new growth. The final phase is referred to as the advanced regenerative stage, during which significant cell proliferation starts. Growth factors, which are neurally derived, determine the processes responsible for the formation of patterns during the last stage. If anything intervenes More...

Fun Starfish Facts for Kids

Structure of Body

Starfish is not really fish because fish is composed of backbones, fins and gills. Starfish is an echinoderm, which is an invertebrate that has a proportional radial body. Instead of scales, starfish species are mostly equipped with a leathery, rigid skin, which protects them against the attack of predators like birds and fishes. Calcium carbonate makes up the skin of all starfishes. Most of the starfish species are equipped with five arms, which extend out of a central point; nonetheless, More...

Feeding a Starfish

Nowadays, marine scientists call starfish “sea stars”, since they are actually not fish, but echinoderms. There are more than two thousand species of sea stars. Most of them have five arms, but others are blessed with up to forty arms. The stomach and mouth of the starfish are located on its bottom. These animals usually push their stomachs from their bodies, wrapping them around the food for digestion. When learning how to feed a starfish, identify what type your starfish More...

Other Cool Starfish Facts

There are various marine creatures, such as manta rays and sharks, which can prey on starfishes and penetrate their solid skin. There are species of birds that can feed on starfishes, which come too close to the water surface. The larger starfish species may sometimes feed on smaller marine species. The lifespan of a starfish can be up to thirty-five years if it is able to get away from its numerous predators. What makes the starfish very different from most More...

Dissecting a Starfish

When considering dissecting a starfish, you must understand that this creature is a sea animal with a proportional endoskeleton. It feeds on mollusks and moves with hundreds of extremely small tube feet. Now, prepare the necessary tools for dissecting the starfish. These include a probe, a scalpel, dissection tray, scissors and pins. You must wear goggles and protective clothing to cover yourself against debris. Pin your starfish into the tray in such a way that its top view faces you. More...
