While humans are working on robotic arms and new limb technology, some animals can regrow their limbs on their own. How do they do this?
The Animal that regrows its head!
“Many animals can regenerate body parts, from starfish to salamanders. But primitive snail fur is unusual, not least because its abilities are so extreme.”
Why Can’t Humans Regenerate Body Parts?
“The snail fur is a pinkish mass of spines, tentacles and polyps just 20 to 30 millimeters in length. The snail fur would seem unremarkable, except for one quality: According to Uri Frank, a scientist at the institute, the creature “in theory — lives forever.”
Limb regeneration: do salamanders hold the key?
“The secret of how salamanders successfully regrow body parts is being unravelled by UCL researchers in a bid to apply it to humans.”
