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.

Starfish Facts on its Ancient History

When it comes to researching about starfish facts on their history, it is actually a very difficult process because starfishes are echinoderms and their species hardly leave any trace in their fossils aside from their external ossicles and spines. This makes it extra difficult for the researchers to spot and identify fossils that are strictly from the starfishes. But according to research findings, starfish fossils can be traced back to Ordovician which is roughly about 450 million years ago. There More...

Starfish Facts about their Habitat

People who want to learn more starfish facts should also look into the habitat and the areas around the world where starfishes can be found. One key fact that you should definitely know is that starfishes will never survive when not in water. You may see a few of them on the beach but if they do not get into the sea soon, they will have a major electrolyte imbalance within their bodies. This is directly related to the starfish’s 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...

Starfish Facts on Reproduction

When it comes to starfish facts on reproduction, things can get a little bit interesting considering the fact that some species can regenerate and grow just from an arm. But the regeneration of one starfish coming from a single arm is under the asexual form of reproduction and only a few species will be able to do that. Regeneration usually requires majority of the central disc to be intact for most of the other species. In terms of sexual reproduction, 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...

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...

Starfish Facts on its Importance in Nature

A lot of people see starfishes as cute animals by the seashore that you can pick up and take pictures of. But there is actually more to these creatures than just their appearances and colors. Not a lot of people understand starfish facts especially about their contribution to nature. Just like any other animal in the marine kingdom, they contribute a lot in Eco diversity and in keeping the food chain running. Scientists and biologists actually called starfishes as keystone More...
