In other words, one generation reproduces asexually (the polyps), ususllya by fragmentaion or budding and the next generation reproduces sexually ( the jellyfish).

Many of you brought up the subject of hybrids and questioned if they were considered species or not. Most hybrids are not fertile descendants,so in this case, neither their progenitors are considered members of the same species nor are they accepted as new species. Nevertheless cross reproduction and the appearance of hybrids is one of the fastest ways of creating new species on the planet and therefore play a vital role in evolution. It has always been known to be frequent in plants. These are considerd new species if they are fertile, reproduce and begin to conquer and adapt to their ecosystem.</p><p> After talking about this in class I came across this national geographic article which I think may be of your interest.

In this video you can see how a bivalve uses its muscular foot to dig itself into the sand. You can see how it leaves its syphons above the level of the sand as it uses them for filtering the water. Molluscs are filter feeders, they take in water through one syphon and the water comes out through the other. They never bury their syphons so as to be able to continue doing this.

Her story is fascinating.</span></span></p><p><span style="font-family: georgia;"><span style="background-color: #6aa84f;"> Nowadays she contributes to environmental conservation by giving conferences all around the world.

This video is about a group of scientists that are working on a way of treating frogs in Cusuco National Park in Honduras. The population of frogs here is declining rapidly due to a disease caused by the chytrid fungus. This fungus has spread worlwide and is causing hundreds of amphibian species to become endagered or even extinct. Some frogs that live in this park are autochthonous, that is, they only live in this part of the world. It is important to understand the importance of biodiversity and appreciate the work of those that study how to conserve nature.</div>
