Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.
The life cycle of all amphibians involves a larval stage that is intermediate between embryo and adult. In most cases this larval stage is a limbless free-living organism that has a tail and is referred to as a tadpole, although in a few cases (e.g., in the Breviceps and Probreviceps genera of frogs) direct development occurs in which the ...
The life cycle is completed when they metamorphose into adults. A few species deposit eggs on land or bypass the tadpole stage. Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on plant matter. Frog skin has a rich microbiome which is important to their health. Frogs ...
Agalychnis lemur, the lemur leaf frog or lemur frog, is a species of frog in the subfamily Phyllomedusinae. [ 3 ] [ 4 ] It is found in Costa Rica, Panama, and adjacent northwestern Colombia. [ 3 ] It is classed as Critically Endangered and threatened by the fungal disease chytridiomycosis .
A giant frog species that hopped alongside dinosaurs and is considered a "living fossil" is now losing ground in its native Chile as climate change and human intervention damage its habitat. The ...
There is some record of people capturing T. typhonius in the wild for the international pet trade, but scientists do not believe this poses a substantial threat to T. macrotis at this time. [1] The frog's range includes some protected parks: Parque Nacional Yasuní, Reserva de Producción de Fauna Cuyabeno, Reserva Ecológica Manglares Churute ...
Death and taxes—the twin inevitabilities of human life.At least, for the moment. If you ask some of the most prominent futurists in the world, death may not be on that (admittedly short and ...
The female lays about 3,000 to 4,000 eggs at a time. The tadpoles hatch, and after two days, start feeding on vegetation, small fish, invertebrates, and even each other. Defending males continue to watch over the tadpoles, which metamorphose within three weeks. During the tadpole's development, the father guards his young.
