Interesting Starfish Facts about its Bodily Processes

The starfish is a very intriguing sea creature and there are definitely a lot of starfish facts about how it survives that will change how you view life under the sea. First, a lot of kids always ask about how these starfishes navigate and transfer themselves from one area to another. Although they have 5 or more arms, they do not literally use these arms to walk on the seabed but they have hundreds of tubes that serve as their feet located on the underside of their bodies.

These tube feet under the starfish do not actually suck but they expel water out of the body. This is part of the water vascular system of the starfish where seawater is being taken and is then released back into the sea. As the tubes open to let the water out, the starfish can now easily glide from one area to another but this is usually a very slow movement.

The digestive system of the starfish is also interesting. They have a gut that usually spans the entire central disc and they also have mouths and anuses for taking in food and releasing body wastes. But starfishes can actually digest food outside of their stomachs with the help of enzymes which means they can eat prey that are larger than their size.

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. The first fact that you can give them is that starfishes are not really fish but they are echinoderms. They are more related to sea cucumbers even if they have a ‘fish’ in their name. You may be able to find 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...

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...

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 on How They Protect Themselves

When a prey is being stalked by predators, the first reaction of the prey is always to flee the scene. It will only be during compromising situations wherein the prey would start to be in fight mode. Unfortunately, starfishes cannot just escape from predators because most of them are generally slow. So they use numerous other defense mechanisms to protect themselves. According to the starfish facts gathered by zoologists, certain species of starfishes have a chemical coating in their bodies More...

Dissecting a Starfish

When considering dissecting a starfish, you must understand that this creature is a sea animal with a proportional endoskeleton. It feeds on mollusks and moves with hundreds of extremely small tube feet. Now, prepare the necessary tools for dissecting the starfish. These include a probe, a scalpel, dissection tray, scissors and pins. You must wear goggles and protective clothing to cover yourself against debris. Pin your starfish into the tray in such a way that its top view faces you. More...
