Keystone species are those that help maintain the balance and survival of an ecosystem; without them, the ecosystem would drastically change, or it would completely disappear. As the name implies, these species are the keystone the ecosystem is based on; they are particularly important because, if they disappear, no other species can replace them. Keystone species are usually predators, but they might also include fungi and plants.

There are some living organisms that cannot breathe the same way that mammals do because they do not have lungs, such as fish. If fish have a respiratory system similar to that of mammals, a single breath underwater will fill its lungs with fluids, making them useless.

The Red Sea in eastern Egypt is full of coral reefs that people from all over the world come just to take pictures next to them and enjoy watching them while diving. However, changes to Earth's climate in recent years have made coral reefs more vulnerable than before. Will they someday lose and be deprived of their habitats? This is what we explore in this article.

Our ecosystems consist of armies of creatures; without their presence the whole ecosystem will collapse.

It has always been understood that life under ice takes the winter season off, but studies have found that life under the ice is very much active.

Sharks can hardly be outswam, which is no wonder given their more than 400-million-year evolutionary history in the ocean.

The great diversity of the Red Sea is not limited only to its wide variety of fishes, but there are plenty of other distinctive sea creatures.
