Starfish Facts on Asexual Methods of Reproduction

Starfishes are animals that are known to be able to multiply through both the sexual and the asexual processes. Based on starfish facts, not all species of starfishes can asexually create an offspring. There are species that strictly multiply through the sexual methods. But the asexual reproduction of starfishes is definitely a very interesting topic especially to kids.

The asexual process of preproduction by starfishes can be accomplished through two methods. These are autotomy and fission. Autotomy is the process of voluntarily cutting an appendage or an arm usually because of self- defense. In starfishes, they can sever their own arm and regenerate that arm to get complete sets of arms again. At the same time, that arm can actually regenerate a new disc from where the other arms can be formed as well. Again, not all species of starfishes are able to perform regeneration from a single arm since majority of the species would need a part of the disc to be present to regenerate.

The other method is through fission. Fission is the process wherein the central disc of the starfish will be divided into two. Each of those parts of the central disc will now regenerate the remaining parts of the missing body of the starfish.

Central Disc of Starfish

Starfish have the capability of re-growing partial bodies or lost arms, after they experience an injury. They typically do this to either reproduce or heal wounds. If you cut a sea star into five sections, each containing a portion of its central disc and an original arm, five new sea stars will be born. For the most part, a sea star can never clone itself except when the targeted clone has a section of the central disc. As the name 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 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...

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...

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...

Handling Alive Starfish

In order to handle a life starfish properly, you need to gently pick it up and not bend or break its arms, which may be somewhat fragile and small on a number of species. Although starfishes are popular for their regeneration capabilities, you must always hold them very cautiously to minimize any possible damage. You have to wrap a moist towel around the starfish or put it in a handy marine environment (a container full of seawater), in case it 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...
