Frogs are more often heard than seen, and other frogs (and researchers) rely on their calls to identify them. Depending on the region that the frog lives in, certain times of the year are better for breeding than others, and frogs may live away from the best breeding grounds when it is not the species’ mating season.
Frogs have a highly developed nervous system that consists of a brain, spinal cord and nerves. Many parts of frog brains correspond with those of humans. It consists of two olfactory lobes, two cerebral hemispheres, a pineal body, two optic lobes, a cerebellum and a medulla oblongata.
Dissection of a frog. Pain is an aversive sensation and feeling associated with actual, or potential, tissue damage. [1] It is widely accepted by a broad spectrum of scientists and philosophers that non-human animals can perceive pain, including pain in amphibians.
In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. [2] It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects.
Fleischmann's Glass Frogs live near fast streams, and these frogs usually inhabit forests up to 2,000 meters above sea level in Central and South America. [4] They have a very wide geographic distribution from Mexico to Ecuador and Suriname and are one of the most altitudinal species of their genus (approximately sea level to above 1600 m). [8]
Researchers said they named the new species after the Latin word for “similar” because of its similarity to other known species of frog. So far, similar rubber frogs have been found in two ...
The next time you declare that you are “freezing to death,” spare a thought for the wood frog who gets so cold in winter that its heart stops beating – but it does not die. Once the spring ...
Sometimes, a behavioural change and warning colouration will be combined, as in certain species of amphibians which have most of their body coloured to blend with their surroundings, except for a brightly coloured belly. When confronted with a potential threat, they show their belly, indicating that they are poisonous in some way.
