Starfish Facts on Reproduction

When it comes to starfish facts on reproduction, things can get a little bit interesting considering the fact that some species can regenerate and grow just from an arm. But the regeneration of one starfish coming from a single arm is under the asexual form of reproduction and only a few species will be able to do that. Regeneration usually requires majority of the central disc to be intact for most of the other species.

In terms of sexual reproduction, starfishes are just like most other animals where a male and a female will need to spawn in order to create new offspring. The male and the female starfishes actually look very similar to each other when it comes to the external physical characteristics. But when they spawn, their internal gonads will be revealed and their sex can be identified. Some species also have both male and female sex organs which means they can reproduce on their own.

Majority of the time, the males release their sperm while the females release their eggs in the sea. Fertilization usually occurs externally but some species have been found to fertilize within their bodies. When the eggs are fertilized, they either stick to rocks or float in the sea until they hatch to become larvae.

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...

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...

Feeding a Red Starfish

When considering feeding a red starfish, you need to observe the animal to see what it is and it is not eating. A red starfish could be feeding on bacteria out of your aquarium glass, but steering away from other foods that you provide for other inhabitants in your tank. As an omnivore, the starfish must be given nutrients from the two sources. If frozen, your food will have to be thawed. Use tweezers or forceps for putting a thawed More...

Researching about Starfish Facts

There will be no starfish facts that people know today if not for the researches and studies done by scientists, zoologists, and biologists. From the time that starfish species were first discovered and studied by humans until today, a wider range of information are already gathered pertaining to these creatures. Researching starfishes is not an easy thing to do since there are thousands of species that are still living. In order to understand the evolution of this creature, researchers would More...

Fun Starfish Facts for Kids

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...

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 More...
