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.

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...

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...

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...

Starfish Facts on its Ancient History

When it comes to researching about starfish facts on their history, it is actually a very difficult process because starfishes are echinoderms and their species hardly leave any trace in their fossils aside from their external ossicles and spines. This makes it extra difficult for the researchers to spot and identify fossils that are strictly from the starfishes. But according to research findings, starfish fossils can be traced back to Ordovician which is roughly about 450 million years ago. There 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...

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...

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...
