The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth. A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs. The animal with the largest lungs in the world is the blue whale.
In total, its lungs have a combined capacity of over 1, gallons of air. Researchers said on Thursday that the red brittle star, called Ophiocoma wendtii, is only the second creature known to be able to see without having eyes — known as extraocular vision — joining a single species of sea urchin.

Food items include mainly frogs, tadpoles, small fishes, snails, shrimp and earthworms.
It will also eat plant material. The eyesight of the Australian Lungfish has been reported to be poor and the location of prey was thought to be based on the sense of smell rather than sight. The recent work of Watt et al has shown that the Australian Lungfish can use electroreception to locate hidden prey. Their research on the anatomy of this species has shown the presence of organs similar to those used for the detection of electric signals in other fishes, such as sharks.
The Australian Lungfish has a single lung, whereas all other species of lungfishes have paired lungs. During dry periods when streams become stagnant, or when water quality changes, lungfishes have the ability to surface and breathe air.
When the Australian Lungfish surfaces to empty and refill its lung the sound is reportedly like that of the "blast from a small bellows". Under most conditions, this species breathes exclusively using its gills. The species can live to at least years of age. The Shedd Aquarium's Australian Lungfish, affectionately known as 'Granddad' see image lived to over 80 years of age and was possibly the oldest fish in captivity.
He was finally euthanised on 5 Feb This species spawns at night from August to December with peak activity in October. Fertilized eggs are stuck to aquatic plants and hatching takes about three weeks.
Growth is very slow, with young reaching 6 cm in length after 8 months and 12 cm after two years. The Australian Lungfish is a protected species and may not be captured without a special permit. The lungfishes first appeared in the fossil record million years ago.
They are relics of ancient fish groups that were related to the ancestors of amphibians, reptiles, birds and mammals. Worldwide, there are six species of lungfishes.
Four species in the genus Protopterus Family Protopteridae are found in Africa. The Australian Lungfish is the only species in the Family Ceratodontidae. The African lungfish Protopterus annectens see image is known for its ability to bury in the mud. At the onset of the dry season when water bodies dry up, this species is able to secrete large quantities of mucous.
The mucous hardens to form a cocoon in which the fish stays dormant for several months. Other species of African lungfishes also have this ability to varying extents. The South American Lungfish can only breathe air. It can survive for months in a resting chamber of moist mud and mucous. The waterbear survives extreme environmental conditions by entering a reversibly suspended metabolic state known as cryptobiosis. The nasal surfaces of camels help conserve water by using hygroscopic properties to remove water from air during exhalation.
