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 the muscles can be found. One of the most interesting aspects of the anatomy of a starfish is the vascular system. Starfishes are not mammals so they do not have blood. Instead, the vascular system makes use of seawater to aid in its movement, gas intake, adhesion, and the handling of food. The body of the starfish is filled with canals where water flows in and out of the system.

But even without actual red blood, the starfish still has a circulatory system with a heart that constantly beats at a rate of 6 times in one minute. The movement of the fluid in this system aids in spreading nutrients in the body but has no connection with respiration unlike humans.

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...

Researching about Starfish Facts

There will be no starfish facts that people know today if not for the researches and studies done by scientists, zoologists, and biologists. From the time that starfish species were first discovered and studied by humans until today, a wider range of information are already gathered pertaining to these creatures. Researching starfishes is not an easy thing to do since there are thousands of species that are still living. In order to understand the evolution of this creature, researchers would 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...

Hunting Techniques

Starfish facts indicate that these animals have a generalist diet which means that can eat almost anything from clams and snails to dying fishes. But with the speed of these starfishes on the bottom of the ocean, one would definitely wonder how these animals can catch or hunt their prey. Starfishes begin hunting their prey through their keen senses. They can actually detect the presence of a prey’s odor. So when their senses detect prey, the legs begin to act 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...

Process of Cooking Starfish

The first step of cooking starfishes is putting eight large pieces of them in a pot filled with cold water through the entire night. Chop these creatures into little pieces as you wake up in the morning. You have to chop each of them whole, which means that nothing should be removed from the starfish. Put the starfish slices into a mortar, along with a small quantity of pepper, salt and butter. Grind the whole mixture into some thin paste. 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...

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...

Starfish Facts on Regeneration

Some of the most fascinating starfish facts are about their abilities in regenerating arms that have been cut. First you must understand why there are instances where a starfish could be missing an arm. The starfishes can actually be bitten by a predator and was able to escape or the starfish voluntarily cut one of its arms so that the predator will be distracted and they can escape. There are also species that cut their arms to reproduce. The duration More...
