Pacific Science 70(2):233-241. https://doi.org/10.2984/70.2.9 The red-legged running frog ( Kassina maculata) has short, slim hind limbs unsuited to jumping. It can move fast by using a running gait in which the two hind legs are used alternately. Slow-motion photography shows, unlike a horse that can trot or gallop, the frog's gait remained similar at slow, medium, and fast speeds. [111] This species can also climb trees and shrubs, and does so at night to catch insects. [112] The Indian skipper frog ( Euphlyctis cyanophlyctis) has broad feet and can run across the surface of the water for several metres (yards). [104] Swimming Common toad ( Bufo bufo) swimming

S2CID 12023942.Although care of offspring is poorly understood in frogs, up to an estimated 20% of amphibian species may care for their young in some way. [170] The evolution of parental care in frogs is driven primarily by the size of the water body in which they breed. Those that breed in smaller water bodies tend to have greater and more complex parental care behaviour. [171] Because predation of eggs and larvae is high in large water bodies, some frog species started to lay their eggs on land. Once this happened, the desiccating terrestrial environment demands that one or both parents keep them moist to ensure their survival. [172] The subsequent need to transport hatched tadpoles to a water body required an even more intense form of parental care. [171] Some species of frog have adaptations that allow them to survive in oxygen deficient water. The Titicaca water frog ( Telmatobius culeus) is one such species and has wrinkly skin that increases its surface area to enhance gas exchange. It normally makes no use of its rudimentary lungs but will sometimes raise and lower its body rhythmically while on the lake bed to increase the flow of water around it.

At the other extreme, the striped burrowing frog ( Cyclorana alboguttata) regularly aestivates during the hot, dry season in Australia, surviving in a dormant state without access to food and water for nine or ten months of the year. It burrows underground and curls up inside a protective cocoon formed by its shed skin. Researchers at the University of Queensland have found that during aestivation, the metabolism of the frog is altered and the operational efficiency of the mitochondria is increased. This means that the limited amount of energy available to the comatose frog is used in a more efficient manner. This survival mechanism is only useful to animals that remain completely unconscious for an extended period of time and whose energy requirements are low because they are cold-blooded and have no need to generate heat. [98] Other research showed that, to provide these energy requirements, muscles atrophy, but hind limb muscles are preferentially unaffected. [99] Frogs have been found to have upper critical temperatures of around 41 degrees Celsius. [100] Locomotion Frogs may lay their in eggs as clumps, surface films, strings, or individually. Around half of species deposit eggs in water, others lay eggs in vegetation, on the ground or in excavations. [133] [134] [135] The tiny yellow-striped pygmy eleuth ( Eleutherodactylus limbatus) lays eggs singly, burying them in moist soil. [136] The smoky jungle frog ( Leptodactylus pentadactylus) makes a nest of foam in a hollow. The eggs hatch when the nest is flooded, or the tadpoles may complete their development in the foam if flooding does not occur. [137] The red-eyed treefrog ( Agalychnis callidryas) deposits its eggs on a leaf above a pool and when they hatch, the larvae fall into the water below. [138] According to genetic studies, the families Hyloidea, Microhylidae, and the clade Natatanura (comprising about 88% of living frogs) diversified simultaneously some 66 million years ago, soon after the Cretaceous–Paleogene extinction event associated with the Chicxulub impactor. All origins of arboreality (e.g. in Hyloidea and Natatanura) follow from that time and the resurgence of forest that occurred afterwards. [38] [39] Figure 1.

But can a dive housing manufacturer successfully make the cross over to manufacture quality surf housings? We all know that the demands and requirements for a surf housing can be vastly different to that of a dive housing. Obviously using a water housing in calm dive conditions compared to large and powerful ocean swells/waves can present different requirements on the housing with the former placing intense impact related pressure on the water housing. Therefore any quality surf housing first and foremost will have to have a strong and robust design to meet the stringent demands of surf photography. Arboreal frogs have pads located on the ends of their toes to help grip vertical surfaces. These are not suction pads, the surface consisting instead of columnar cells with flat tops with small gaps between them lubricated by mucous glands. When the frog applies pressure, the cells adhere to irregularities on the surface and the grip is maintained through surface tension. This allows the frog to climb on smooth surfaces, but the system does not function efficiently when the pads are excessively wet. [53] Liddell, Henry George; Scott, Robert (1940). "οὐρά". A Greek-English Lexicon. Perseus Digital Library. In most cars 30mph will almost always burn less fuel for a given journey than 60mph. The energy (fuel) needed to get from A to B is primarily determined by two factors: the efficiency of the car's drive chain (engine, gearbox, differential etc) and external resistance to the car's movement.
