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.

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 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...

Drying a Starfish

Starfish can be dried by first mixing equal portions baking soda and table salt. Apply a thin layer of this mixture to the inside bottom of a shallow, small cardboard box. Then put that box aside for later use. In a casserole dish, combine one part “for home use” bleach and three parts water together. You will be needing enough of this solution for submerging the starfish completely. Place the starfish in your bleach solution then let it soak for 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...

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...

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...

Feeding a Starfish

Nowadays, marine scientists call starfish “sea stars”, since they are actually not fish, but echinoderms. There are more than two thousand species of sea stars. Most of them have five arms, but others are blessed with up to forty arms. The stomach and mouth of the starfish are located on its bottom. These animals usually push their stomachs from their bodies, wrapping them around the food for digestion. When learning how to feed a starfish, identify what type your starfish 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.
