Physical Description and Feeding
Cryptobranchids are largest salamanders, with large folds of skin along their flanks. These help increase the animal's surface area, allowing them to absorb more oxygen from the water. They have four toes on the forelimbs, and five on the hind limbs. Their metamorphosis from the larval stage is incomplete, so that the adults retain gill slits (although they also have lungs), and lack eyelids. They can reach a static size of 2 meters (6 feet 6 inches) in length. They weigh up to 145 lbs. Chinese Giant Salamanders have lived as long as 75 years in captivity. The Chinese giant salamander eats aquatic insects, fish, frogs and also crabs and shrimp.
They hunt mainly at night, and as they have poor eyesight, they use sensory nodes on their head and body to detect minute changes in water pressure, allowing them to detect their prey.

Famous quotes containing the words physical, description and/or feeding:
“Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.”
—Susanne K. Langer (1895–1985)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
“I am still a learner, not a teacher, feeding somewhat omnivorously, browsing both stalk and leaves; but I shall perhaps be enabled to speak with more precision and authority by and by,—if philosophy and sentiment are not buried under a multitude of details.”
—Henry David Thoreau (1817–1862)
