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 water vascular system where water needs to constantly flow within the tubes in their bodies.

Because electrolytes are essential in creating equilibrium within the starfishes’ bodies, these animals are not just strict water creatures, but they are strict marine sea creatures as well. This means that they will only be able to survive in the oceans and in the sea where the water is salty. Freshwater environments such as lakes and rivers will not be suitable for the starfishes.

Starfishes are also found all over the world but populations thrive at tropical seas where sea temperatures are perfect for their systems although there are some species that are able to survive colder temperatures. Starfishes also stay at the bottom of the sea or the ocean.

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...

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...

Researching about Starfish Facts

There will be no starfish facts that people know today if not for the researches and studies done by scientists, zoologists, and biologists. From the time that starfish species were first discovered and studied by humans until today, a wider range of information are already gathered pertaining to these creatures. Researching starfishes is not an easy thing to do since there are thousands of species that are still living. In order to understand the evolution of this creature, researchers would More...

Preserving a Starfish

The first thing that you will do when preserving the starfish is cleaning it. Use a little mild soap and warm water for washing the starfish. Soak the animal for about forty-eight hours in rubbing alcohol. You do not have to clean the creature first, but you may choose to do so. If rubbing alcohol is not what you prefer to use, you may alternatively use a mixture of five parts water and one part formaldehyde. This solution will give More...

Feeding a Starfish

Nowadays, marine scientists call starfish “sea stars”, since they are actually not fish, but echinoderms. There are more than two thousand species of sea stars. Most of them have five arms, but others are blessed with up to forty arms. The stomach and mouth of the starfish are located on its bottom. These animals usually push their stomachs from their bodies, wrapping them around the food for digestion. When learning how to feed a starfish, identify what type your starfish 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...
