Chimaeras are cartilaginous fish in the order Chimaeriformes, known informally as ghost sharks, ratfish, spookfish, or rabbitfishes. They grow up to 150 cm (4.9 ft) in length, and have elongated, soft bodies, with a bulky head and a single gill-opening. For defense, most chimaeras have a venomousspine located in front of the dorsal fin. At one time a "diverse and abundant" group (based on the fossil record), their closest living relatives are sharks, though in evolutionary terms they branched off from sharks nearly 400 million years ago and have remained isolated ever since, typically confined to deep water.
Naja naja or the Indian cobra is a species of venomous snake found in Indian subcontinent. It is one of the big four members and it is one of the species which are responsible for causing the most snakebite cases in India. This snake is revered in Indian mythology and culture and is often seen with snake charmers. It is now protected in India under the Indian Wildlife Protection Act (1972).
The purple-striped jelly (Chrysaora colorata, formerly Pelagia colorata) is a species of jellyfish existing primarily off the coast of California, USA, in Monterey Bay. The bell (body) of the jellyfish is up to 70 cm in diameter, typically with a radial pattern of stripes. The tentacles vary with the age of the individual, consisting typically of eight marginal long dark arms, and four central, frilly, oral arms.
Mayflies are insects assigned to the Order Ephemeroptera. They are related to dragonflies and damselflies. Their development takes place in freshwater and typically takes a year. During that time, they are known as "nymphs". The adults are short-lived, from a few hours to a few days depending on the species. About 2,500 species are known worldwide. Depicted here is a female subimago of the March Brown, Rhithrogena germanica, which is a faunistic rarity and on the red list of endangered species.
Biodiversity is the diversity of and in living nature. Diversity, at its heart, implies the number of different kinds of objects, such as species. To increase the genetic diversity of U.S.corn, the Germplasm Enhancement for Maize (GEM) project seeks to combine exotic germplasm, such as this unusually colored and shaped maize from Latin America, with domestic corn lines.
A mating pair of European or Common Toads(Bufo bufo) occupying the position known as amplexus. This is indeed a common toad, with a range that includes North Africa, Europe except Ireland, and across North Asia into Siberia. In some regions, toads are threatened by roads disrupting their spawning migrations, and in many places, tunnels have been built to allow them to cross roads.
