Starfish Facts on Environmental Dangers and Threats

According to zoologists who study starfishes and their impact to the environment, these sea creatures have a very important role in the oceans. They may look like decorations in the ocean floor but they are actually considered as keystone species because they contribute in creating balance of species under the sea which can be done through predation. With the starfish facts that people already know, it will be a good start to know what these animals do so that people will give importance to them too.

Unfortunately, there are natural and man-made threats to the numbers of starfishes around the world. The fluctuating temperatures of the sea water can contribute to the migration of starfishes to area where the temperature is more suitable. According to researches, areas that do not have much starfishes can be infested with opportunist mussels. There is also a bacteria found in seawater that can cause wasting disease to starfishes.

The pollution caused by humans also affects these starfishes. When people pollute the waters, the contaminants in the water can get inside the bodies of the starfishes because of their vascular system. These starfishes do not have a good filtering system so oils and other pollutants can remain inside their systems and affect how they function.

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 More...

Feeding a Red Starfish

When considering feeding a red starfish, you need to observe the animal to see what it is and it is not eating. A red starfish could be feeding on bacteria out of your aquarium glass, but steering away from other foods that you provide for other inhabitants in your tank. As an omnivore, the starfish must be given nutrients from the two sources. If frozen, your food will have to be thawed. Use tweezers or forceps for putting a thawed More...

Drying a Starfish

Starfish can be dried by first mixing equal portions baking soda and table salt. Apply a thin layer of this mixture to the inside bottom of a shallow, small cardboard box. Then put that box aside for later use. In a casserole dish, combine one part “for home use” bleach and three parts water together. You will be needing enough of this solution for submerging the starfish completely. Place the starfish in your bleach solution then let it soak for More...

Modern Uses

Based on starfish facts, these animals are definitely very useful in keeping the equilibrium and balance in the food chain under the sea. These animals have a very wide preference when it comes to their diet which is why they can help control the number of opportunist organisms in the oceans. But aside from their usefulness in the environment, there are also other uses of these starfishes by humans. A common use of starfishes today is in the seawater aquariums. More...

Creating a Starfish Artwork

When considering making a starfish necklace, put a sheet of paraffin paper atop any plane surface. Use glue for drawing the starfish shape little enough to be used as a necklace pendant. Use a toothpick for fixing the shape, if you unintentionally mess up your drawing. Create a letter “V” out of a paper clip. Place both ends of this clip into the adhesive at the top of any of the arms of your starfish. Sprinkle glitter or sand lightly More...

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...

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...
