Body Cooling

All types of living organisms will always have a suitable environment where they can survive. Slight changes in the environment will be acceptable because of an organism’s ability to adapt. But when the environment gets too extreme, the organism’s adaptation mechanisms may not work anymore. Temperature plays a vital role when animals choose their habitat. Starfishes live under the sea but they can be affected by water temperature levels too. Based on starfish facts gathered by researchers, starfishes can start to die when they are exposed to temperatures higher than 35 degrees Celsius.

Because the starfish is submerged in water, it has a unique way of cooling itself. If dogs can pant and human beings can sweat to release heat from their bodies, starfishes can rely on two essential mechanisms to decrease body temperature. The first one is through the vascular system where water continually flows inside and out of the body of the starfish. They can move to a location that has cooler water to introduce cold water inside their system.

The other mechanism that they use is through their network of nerves that will be able to channel heat to their arms instead of focusing it in their central discs. Starfishes will die quicker if their discs are warmer so they transfer the heat to their extremities.

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...

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 More...

Starfish Facts

Starfish, also popularly recognized equally as sea stars, common name for 5 orders and about 1500 living species of marine invertebrate characterized by radially arranged arms having locomotory tube feet. Actually, starfish cannot be considered as fish in spite of the name provided to these sea animals. Some known starfish facts are that they belong to the group called echinoderms. They can be found in great numbers in the depths of the ocean and as well as in shallow waters. More...

Starfish Facts on Physical Characteristics

When you look at a starfish, you can easily be captivated by its appearance. There are thousands of species of starfishes that you can find and only a few of them are those that you see on the shorelines. Most of them are found on the seabed where they can easily catch prey. The seabed is also where you can find species of starfishes with very interesting physical features. One of the starfish facts about its appearance is that the More...

Starfish Facts on Regeneration

Some of the most fascinating starfish facts are about their abilities in regenerating arms that have been cut. First you must understand why there are instances where a starfish could be missing an arm. The starfishes can actually be bitten by a predator and was able to escape or the starfish voluntarily cut one of its arms so that the predator will be distracted and they can escape. There are also species that cut their arms to reproduce. The duration 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...

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...

Process of Cooking Starfish

The first step of cooking starfishes is putting eight large pieces of them in a pot filled with cold water through the entire night. Chop these creatures into little pieces as you wake up in the morning. You have to chop each of them whole, which means that nothing should be removed from the starfish. Put the starfish slices into a mortar, along with a small quantity of pepper, salt and butter. Grind the whole mixture into some thin paste. More...

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...
