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.

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...

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 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...

Starfish Facts on Environmental Dangers and Threats

According to zoologists who study starfishes and their impact to the environment, these sea creatures have a very important role in the oceans. They may look like decorations in the ocean floor but they are actually considered as keystone species because they contribute in creating balance of species under the sea which can be done through predation. With the starfish facts that people already know, it will be a good start to know what these animals do so that people More...

Starfish Facts on Reproduction

When it comes to starfish facts on reproduction, things can get a little bit interesting considering the fact that some species can regenerate and grow just from an arm. But the regeneration of one starfish coming from a single arm is under the asexual form of reproduction and only a few species will be able to do that. Regeneration usually requires majority of the central disc to be intact for most of the other species. In terms of sexual reproduction, More...

Is your Starfish Still Alive or Already Dead?

In order to tell whether a starfish is alive or dead, you need to observe it. Starfishes do not move frequently, but they move whenever they are fed. The starfish is alive if it is moving. Now, wear a pair of gloves that are waterproof. Gently scoop up the starfish without getting it out of the water. The animal can be stressed by any sudden alterations in its environment, and caused to start disintegrating or to shed their limbs. Being 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...
