Although rainforests make up only two percent of the earth's surface, over half the world's wild plant, animal and insect species live there.

The species faded away.

Darwin wrote "the Origin of Species".

Long before Darwin's theory of evolution, Buffon had surmised that species evolved very slowly under different material circumstances.

Fresh-water fish include some designated as protected species. You're not allowed to catch or buy them.

The biologist classifies the newly found species in its own genus, whereas other taxonomists want to put it into an established genus.

It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.

This species of moth has evolved an ingenious camouflage for blending into its surroundings.

Some species gradually develop elaborate repertoires of dozens or even hundreds of variants of a basic song.

There exists a beautiful, colorful species of turkey in the Yucatán Peninsula called the "ocellated turkey," or "el pavo ocelado."

Cabbage, cauliflower, broccoli, and Brussels sprouts are all cultivars of the same species.

It has been estimated that, as a result of the destruction, fifty species of wildlife are disappearing from the earth each day.

Man who preys both on the vegetable and animal species, is himself a prey to neither.

Among these there may be new sources of food fish and new species of other creatures.

If we don't make the utmost effort to protect the rainforests, many of the rare species in them will become extinct.
