Types of Starfish
There are a lot of types of starfishes in the ocean. In fact, according to the research, there are about 1,600 types of starfishes in all types of habitats, like tidal pools, rocky shores, kelp beds, coral reefs. Moreover, we even find some of them enjoying their sleep on the seabeds.
In addition, if we go a bit deeper, let’s say, nine thousand meters deep, then most of the starfishes in that zone will have spiny skin and five arms. In fact, some of them can even grow up to 50 arms. You will also find pincer-like organs in those arms.
So, let’s name a few starfishes. For example, have you ever heard of a chocolate starfish? Well, it’s not the studio album of the famous American band Limp Bizkit. Actually, this chocolate starfish is quite popular among the people, however, not as a creature, but as slang that denotes the spread buttocks. In reality, there’s no such thing as chocolate starfish.
However, you have probably heard of Crown of thorns starfish. It’s a large starfish that hunts coral polyps. Furthermore, it has venomous thorn spines covering the upper layer of its body. This crown of thorns starfish is one of the largest starfish in the world.
What do Starfish Eat?
Firstly, it’s important to know that these beautiful creatures aren’t that choosy when it comes to food for survival. However, it’s true that these animals are mostly carnivorous in nature, therefore, these organisms eat slow-moving creatures, such as Gastropods, planktons, organic detritus, small fishes, as well as bivalves. In addition, there are some species of starfish that feed on anemones. They also eat sea cucumbers, chitons, hydroids, sea urchins, and small fish eggs.
Can You Eat Starfish?
Now, this is quite a shocking fact. Yes, they are edible and in Chinese markets, you will often see them on the plates. However, it’s worth mentioning that not all can eat this with a straight face, because the taste may not seem appealing to them.
So how’s the taste? Well, according to those, who have tried eating a starfish said that they have a taste similar to the Sea urchins, though, a bit more bitter, and perhaps a bit creamier as well. In addition, some people have also suggested that they taste like the brain area of the crabs.
Do Starfish have Brain?
According to the science books, starfish belongs to the phylum Echinodermata. Therefore, they don’t have any centralized brain. So, how do they perform their works, and most importantly, how do they survive? Well, they have a very complex nervous system on their entire body that allows them to perform sensory functions, like touch, light, feel the temperature, etc.
As it doesn’t have any brain, it cannot function the normal actions. Therefore, it follows the stimulus through those complex nervous pores on their body. For example, a starfish can’t hunt for its food, however, if one of its victims gets in touch, it will proceed to eat the food. This is exactly what helps a starfish to survive.
Do Starfish have Eyes?
So, if they don’t have any central brain, then you might be thinking that they don’t even have eyes right? Well, that’s where you are wrong. It’s surprising that these little creatures have eyes. In addition to their unusual anatomy, they have their eyes on the end of their arms. While it’s true that they don’t possess beautiful and distinct eyes like ours, they are able to perform functions, such as detecting the different shades of lights.
How do Starfish Reproduce?
A starfish can reproduce both sexually and asexually. So, how does this work? Let us tell you. In the former method, the process of fertilization occurs in the water where both male and female starfishes release their sperm and egg.
Thereafter, the fertilized embryos become zooplankton, which, eventually undergo metamorphosis and become adults. In another case, some species of starfish breed eggs by sitting over them.
There’s another asexual method as well, where the creature detaches a part of their arm or central disk. Thereafter it develops into another starfish. In fact, according to research, in past, people killed many starfishes by chipping them. However, they were able to regenerate.
Our world has a lot of beautiful animals and creatures. Therefore, it’s always interesting to know more about them. In this article, we mentioned some interesting facts about a very popular creature, the starfish. We hope this article helped you to know more about them.
