External Threats

The greatest threat to starfish is similar one which endangers most other seawater animals: human beings. Starfish needs clean and clear water as its habitat. When humans permit water pollutants to flow into the seas and oceans, these species can get extremely unhealthy and even die. In addition, there are several cultures that allow the eating of starfish. In case too many starfishes are brought away from any area, these beautiful seawater creatures will be deprived of the opportunity to multiply and worse, they can completely disappear. This threatening activity is referred to as “over harvesting”. We are unfortunate that most of their species continue to thrive and new species are always discovered as scientists keep on harmlessly exploring their habitats.

Global warming is believed to be a contributory factor to the disappearance of some starfish habitats. Most starfishes live in sea coral beds, which are unfortunately not growing as they must due to warmer waters. Although scientific researchers have never yet clearly defined the effect of global climate change on starfishes, the obvious harm of warmer waters is the decrease in the amount of food sources that these creatures basically need. Primarily, starfish feeds on snails, mollusks and clams. All of these animals tend to multiply less fast in warm temperatures.

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...

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...

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...

Starfish Facts

Starfish, also popularly recognized equally as sea stars, common name for 5 orders and about 1500 living species of marine invertebrate characterized by radially arranged arms having locomotory tube feet. Actually, starfish cannot be considered as fish in spite of the name provided to these sea animals. Some known starfish facts are that they belong to the group called echinoderms. They can be found in great numbers in the depths of the ocean and as well as in shallow waters. 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...

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...

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...
