Spines of Starfish Facts

If you find out about starfish facts, you will know that not all species of starfishes have spines on their backs. But majority of the living species have spines which are major parts of their exterior anatomy. These spines are extensions of the external dermis of the starfish which are composed of calcium carbonate. The spines may also be of different color than the rest of the body. Their tips can be sharp and pointed while others can be curved and blunt.

Unlike other animals that use their external appearances to attract a female for mating, starfishes use these spines to intimidate their enemies. Other sea creatures that may want to eat the starfish can feel threatened about the spines as they approach them. This defense mechanism is very effective as well considering the fact that starfishes cannot just move away from their predators.

The spines of the starfishes are also used for protection. Because they are sharp, predators will find it painful to bite on them and may just want to spit them out. If there are any arms that the predators have bitten off, the starfish can regenerate it back for the next months. There are even species of starfishes that have pinchers in their spines which can snap on approaching predators.

Hunting Techniques

Starfish facts indicate that these animals have a generalist diet which means that can eat almost anything from clams and snails to dying fishes. But with the speed of these starfishes on the bottom of the ocean, one would definitely wonder how these animals can catch or hunt their prey. Starfishes begin hunting their prey through their keen senses. They can actually detect the presence of a prey’s odor. So when their senses detect prey, the legs begin to act More...

Eliminating Fish Odor from Starfish

The first step of ridding starfish of the fish odor is scraping away any leftover tissue from its underside using a little butter knife. Also, brush off all organic matter, such as seaweed and bugs, which may be sticking to the shell’s spiny top. Combine one part water and three parts bleach together in a large mixing bowl. You have to make sure that the depth of this mixture is enough to soak the starfish that you would like to More...

Handling Alive Starfish

In order to handle a life starfish properly, you need to gently pick it up and not bend or break its arms, which may be somewhat fragile and small on a number of species. Although starfishes are popular for their regeneration capabilities, you must always hold them very cautiously to minimize any possible damage. You have to wrap a moist towel around the starfish or put it in a handy marine environment (a container full of seawater), in case it More...

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...

External Threats

The greatest threat to starfish is similar one which endangers most other seawater animals: human beings. Starfish needs clean and clear water as its habitat. When humans permit water pollutants to flow into the seas and oceans, these species can get extremely unhealthy and even die. In addition, there are several cultures that allow the eating of starfish. In case too many starfishes are brought away from any area, these beautiful seawater creatures will be deprived of the opportunity to More...

Locating a Starfish

If you want to find a starfish, go to a nearby rocky beach. Typically, starfish stick to underwater rocks near the seashore. This is the best area to locate these wonderful marine creatures. It is a good idea to look forward to low tide. It is at low tide that the sea reveals a lot of rocks, which have been underwater. In addition, it leaves behind rock pools where there is a vast variety of sea creatures. The best time More...

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 More...
