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 or causes a deviation from such patterns while the sea star is regenerating, then the end result will be probably deformed.

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...

Creating a Starfish Artwork

When considering making a starfish necklace, put a sheet of paraffin paper atop any plane surface. Use glue for drawing the starfish shape little enough to be used as a necklace pendant. Use a toothpick for fixing the shape, if you unintentionally mess up your drawing. Create a letter “V” out of a paper clip. Place both ends of this clip into the adhesive at the top of any of the arms of your starfish. Sprinkle glitter or sand lightly More...

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...

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...

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...

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...

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...

Replacing missing limbs is not the only way a sea star regenerates. The starfish can also asexually reproduce by tearing its own body apart. Each of the body sections has the potential to develop into a new starfish, which is genetically similar to other segments from the same creature. Sea stars also use this ability for cloning themselves after an injury or attack divides their body into parts, as once was prevalent when oyster fishers used to cut sea stars up before they throw them back into the water. The fishermen believed that they were ending the lives of sea stars, but were in fact causing their population to increase.
