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 thick layer of skin that these animals have is the dermis. The dermis layer of starfishes can differ from one species to another especially in terms of structure and texture. But all of these starfishes have a dermis that is abundant with ossicles. These ossicles are made up of calcium carbonate and they are the components of the starfish’s endoskeleton. Some starfishes can have endoskeletons with spines to protect them from predators but some also have dermis layers that are smooth and leathery.

This endoskeleton serves as the armor of the starfish. Because it cannot do much to protect itself, some starfishes can also have numerous spikes not only in the middle of the central disc but also scattered all throughout the arms. Although starfishes have a 5-point symmetry body presentation, this does not mean that a starfish can only have 5 arms.

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...

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...

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...
