Fireflies emit light mostly to attract mates, although they also communicate for other reasons as well, such as to defend territory and warn predators away. In some firefly species, only one sex lights up. In most, however, both sexes glow; often the male will fly, while females will wait in trees, shrubs and grasses to spot an attractive male. If she finds one, she’ll signal it with a flash of her own.
– Fireflies eat other fireflies.
– Fireflies have short lifespans (1 year).
– Fireflies are found on almost every continent.
– Fireflies are medically and scientifically useful.

Ecuador’s Yasuni National Park park is a refuge to more than twenty types of endangered mammals, and a single hectare of forest is home to more than 100,000 species of insects. More amazingly, an estimated eighty percent of the species living in there are still unknown to scientists. But now, the threat of oil extraction means those species could be destroyed before they are even discovered. Al Jazeera’s David Mercer reports from the Yasuni Biosphere Reserve.
The Siamese fighting fish, also sometimes colloquially known as the betta (Betta splendens), is a species in the gourami family which is popular as an aquarium fish. Siamese fighting fish have upturned mouths and are primarily carnivorous surface feeders, although some vegetable matter may be eaten. In the wild, they feed on zooplankton, crustaceans, and the larvae of mosquitoes and other water-bound insects
These carnivorous plants make light work of any insects that stray into their deadly clutches. This set showcases an array of bug-eating plants, from the Venus flytrap – beloved of children the world over – to the Cape sundew, which lures insect life in with drops of sweet-smelling fluid on the highly-adhesive tentacles that line its leaves. Surrounding tentacles then move to further ensnare the insect, before glands on the leaf start to release digestive enzymes – liquefying the insect’s internal organs and allowing them to be digested by the plant.
