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 suggests, the central disc refers to the center of the body of a starfish. A separated arm containing a portion of the central disc is going to produce a clone, though one without any part of the central disc won’t. However, a separated arm will sometimes re-develop some extra arm tissue.

Cloning with no central disc is very uncommon, but it has been observed by researchers in the Linckia diplax species. The thick, long separated arms of this type of starfish may sometimes develop a new tiny central disc containing four little arms, which all subsequently grow to optimal size. By and large, scientists are unsure whether this capability is only present in intentionally removed limbs, as take place in an asexual reproduction, or whether a limb separated during an attack or injury may as well develop an entirely new clone.

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...

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...

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...

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...

Eliminating Fish Odor from Starfish

The first step of ridding starfish of the fish odor is scraping away any leftover tissue from its underside using a little butter knife. Also, brush off all organic matter, such as seaweed and bugs, which may be sticking to the shell’s spiny top. Combine one part water and three parts bleach together in a large mixing bowl. You have to make sure that the depth of this mixture is enough to soak the starfish that you would like to 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...

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...

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...

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...
