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.

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...

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...

Starfish Facts on Asexual Methods of Reproduction

Starfishes are animals that are known to be able to multiply through both the sexual and the asexual processes. Based on starfish facts, not all species of starfishes can asexually create an offspring. There are species that strictly multiply through the sexual methods. But the asexual reproduction of starfishes is definitely a very interesting topic especially to kids. The asexual process of preproduction by starfishes can be accomplished through two methods. These are autotomy and fission. Autotomy is the process 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...

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...

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...

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...
