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 was also evidence that numerous species of starfishes became extinct as scientists were able to find starfish beds amid fossil layers. Thankfully, starfishes have the ability to quickly diversify their own species. The surviving species were able to evolve rapidly that they were able to morph new species from themselves.

The unique thing about starfishes and their echinoderm ancestors is that the ancient echinoderms were believed to be symmetrical in a bilateral fashion which is unlike the radial symmetry that starfishes evolved to be. But the radial symmetry of the starfishes today does not imply that they have stemmed from the same ancestors as jelly fishes which also have radial symmetrical bodies. Today, there are over 1,500 recorded species of starfishes that are still living.

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...

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...

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...

Handling Dead Sea Stars

Also referred to as sea stars, starfish are marine echinoderms that you can find on tide pools and beaches across the globe. National Geographic reports that there are more than two thousand species of starfish, though they all have the same physical appearance, which is composed of brittle and boney calcified skin. In the event that you find this creature, either dead or alive, you must handle it very carefully so that its fragile arms, will not be injured or More...

Flattening Dried Sea Stars

Dried sea stars can make a good inclusion in your beach- or ocean-themed handicraft project. Along with some shells, they can be placed on picture frames and mirrors, and even in glass-top tables and clear lamps. Moreover, a lot of crafters glue dried sea stars onto ornamental nets, which are utilized as hangings on the wall. It is possible to make a dried starfish flat by first rehydrating it then repositioning its limbs. You can make use of this method 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...

Eliminating Fish Odor from Starfish

The first step of ridding starfish of the fish odor is scraping away any leftover tissue from its underside using a little butter knife. Also, brush off all organic matter, such as seaweed and bugs, which may be sticking to the shell’s spiny top. Combine one part water and three parts bleach together in a large mixing bowl. You have to make sure that the depth of this mixture is enough to soak the starfish that you would like to More...
