Product Information

Morphology and physiology A bullfrog skeleton, showing elongated limb bones and extra joints. Red marks indicate bones which have been substantially elongated in frogs and joints which have become mobile. Blue indicates joints and bones which have not been modified or only somewhat elongated. The call or croak of a frog is unique to its species. Frogs create this sound by passing air through the larynx in the throat. In most calling frogs, the sound is amplified by one or more vocal sacs, membranes of skin under the throat or on the corner of the mouth, that distend during the amplification of the call. Some frog calls are so loud that they can be heard up to a mile (1.6 km) away. [87] Additionally, some species have been found to use man-made structures such as drain pipes for artificial amplification of their call. [88] The coastal tailed frog ( Ascaphus truei) lives in mountain streams in North America and does not vocalize. [89] Unlike John England (N&Q, 4 May) I interpreted the original query as asking what speed (30mph or 60mph) is the most fuel efficient. There is a trade-off: engine efficiency increases with road speed, but higher speeds incur increased air resistance (as the square of the speed). Consequently, fuel economy is maximised somewhere between 30mph and 60mph, depending on the capacity of the vehicle – typically 40mph for a 1600cc diesel car and 60mph for a 1300cc petrol car. The eggs are 0.5–1mm (0.020–0.039in) in diameter and cohere in a gelatinous mass or long ribbon, which in sargassumfish are up to a metre (3.3ft) long and 16cm (6.5in) wide. These egg masses can include up to 180,000 eggs. [7] [13] For most species, the eggs drift on the surface. After two to five days, the fish hatch and the newly hatched alevin are between 0.8 and 1.6mm (0.031 and 0.063in) long. For the first few days, they live on the yolk sac while their digestive systems continue to develop. The young have long fin filaments and can resemble tiny, tentacled jellyfish. For one to two months, they live planktonically. After this stage, at a length between 15 and 28mm (0.59 and 1.10in), they have the form of adult frogfish and begin their lives on the sea floor. Young frogfish often mimic the coloration of poisonous sea slugs or flatworms. A car burns fuel slower at 30mph than at 60mph, but on a given journey the engine is running for twice as long. So which is cheaper?

Some frogs protect their offspring inside their own bodies. Both male and female pouched frogs ( Assa darlingtoni) guard their eggs, which are laid on the ground. When the eggs hatch, the male lubricates his body with the jelly surrounding them and immerses himself in the egg mass. The tadpoles wriggle into skin pouches on his side, where they develop until they metamorphose into juvenile frogs. [180] The female gastric-brooding frog ( Rheobatrachus sp.) from Australia, now probably extinct, swallows her fertilized eggs, which then develop inside her stomach. She ceases to feed and stops secreting stomach acid. The tadpoles rely on the yolks of the eggs for nourishment. After six or seven weeks, they are ready for metamorphosis. The mother regurgitates the tiny frogs, which hop away from her mouth. [181] The female Darwin's frog ( Rhinoderma darwinii) from Chile lays up to 40 eggs on the ground, where they are guarded by the male. When the tadpoles are about to hatch, they are engulfed by the male, which carries them around inside his much-enlarged vocal sac. Here they are immersed in a frothy, viscous liquid that contains some nourishment to supplement what they obtain from the yolks of the eggs. They remain in the sac for seven to ten weeks before undergoing metamorphosis, after which they move into the male's mouth and emerge.

During the evolutionary history of frogs, several different groups have independently taken to the air. [124] Some frogs in the tropical rainforest are specially adapted for gliding from tree to tree or parachuting to the forest floor. Typical of them is Wallace's flying frog ( Rhacophorus nigropalmatus) from Malaysia and Borneo. It has large feet with the fingertips expanded into flat adhesive discs and the digits fully webbed. Flaps of skin occur on the lateral margins of the limbs and across the tail region. With the digits splayed, the limbs outstretched, and these flaps spread, it can glide considerable distances, but is unable to undertake powered flight. [125] It can alter its direction of travel and navigate distances of up to 15m (50ft) between trees. [126] Life history Life cycle of the green frog Nafis, Gary (2012).

An Eocene frogfish from Monte Bolca, Italy: The earliest known skeletal record for the family We are hoping they will live to a great age and enjoy the day each time it comes around; usually conveyed with sincerity, but with irony by anyone counting on a swift inheritance. In November, 1970, NASA sent two bullfrogs into space for six days during the Orbiting Frog Otolith mission to test weightlessness.
