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.

Anatomy of the Starfish Facts

A lot of starfish facts talk about the anatomy of this sea creature. The shape of the common starfish which is what people perceive as a star is already interesting as it is. But if you look into the structure both internal and external parts of the starfish, you will really be fascinated by this animal. Just like humans, the starfish has different skin layers such as the epidermis and the dermis. But they also have an epithelium layer where More...

Fun Starfish Facts for Kids

Kids are always inquisitive especially if they see something that looks interesting. Starfishes always catch their attention because of their appearance and it will be fun if you give a few starfish facts to your kids if they ask.

Handling Dead Sea Stars

Also referred to as sea stars, starfish are marine echinoderms that you can find on tide pools and beaches across the globe. National Geographic reports that there are more than two thousand species of starfish, though they all have the same physical appearance, which is composed of brittle and boney calcified skin. In the event that you find this creature, either dead or alive, you must handle it very carefully so that its fragile arms, will not be injured or More...

Starfish Facts on their Senses

Even if starfishes look very peculiar and different from the rest of the animals that you typically see, they still have typical body functions and processes that other animals commonly share. They also have senses such as seeing, touching, and smelling. These senses may be some starfish facts that you may not have heard before. In terms of vision, starfishes actually have vision sensors which are eyespots that are specially located at the far ends of the starfish’s arms. These 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...

Starfish Facts on their Diet

Starfishes are among the most fun- looking marine animals that kids really want to pick when they go to the beach. Because of their appearance, people get more interested about these animals. One of the common questions about starfish facts that kids ask is about the food and the diet of starfishes. The diet of these sea creatures is actually quite interesting because of the variety of food that they eat. There are more than one species of starfishes in 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...

Starfish Facts on Movement

Starfishes are definitely not popular for their speed. Majority of the species of starfishes can actually just cover a distance of less than 10 inches in a single minute. Even if their speed when moving is not something that might interest the people, the method on how they transfer from one place to another is certainly fascinating. These are some of the starfish facts that many people want to know more about. If you take a look at the underside 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...
