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.

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...

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 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...

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 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...

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...

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...
