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.

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 Physical Characteristics

When you look at a starfish, you can easily be captivated by its appearance. There are thousands of species of starfishes that you can find and only a few of them are those that you see on the shorelines. Most of them are found on the seabed where they can easily catch prey. The seabed is also where you can find species of starfishes with very interesting physical features. One of the starfish facts about its appearance is that the More...

Modern Uses

Based on starfish facts, these animals are definitely very useful in keeping the equilibrium and balance in the food chain under the sea. These animals have a very wide preference when it comes to their diet which is why they can help control the number of opportunist organisms in the oceans. But aside from their usefulness in the environment, there are also other uses of these starfishes by humans. A common use of starfishes today is in the seawater aquariums. More...

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...

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...

Structure of Body

Starfish is not really fish because fish is composed of backbones, fins and gills. Starfish is an echinoderm, which is an invertebrate that has a proportional radial body. Instead of scales, starfish species are mostly equipped with a leathery, rigid skin, which protects them against the attack of predators like birds and fishes. Calcium carbonate makes up the skin of all starfishes. Most of the starfish species are equipped with five arms, which extend out of a central point; nonetheless, More...

Starfish Facts about their Habitat

People who want to learn more starfish facts should also look into the habitat and the areas around the world where starfishes can be found. One key fact that you should definitely know is that starfishes will never survive when not in water. You may see a few of them on the beach but if they do not get into the sea soon, they will have a major electrolyte imbalance within their bodies. This is directly related to the starfish’s More...
