Page "Amphibian" Paragraph 49

Salamanders use their tails in defence.

Some species in the Plethodontidae have a weak zone at the base of the tail and if the salamander is in danger or if the tail is grabbed by a predator, it breaks off, a process known as autotomy.

Other salamanders are also prepared to drop their tails to save their lives.

The tail may continue to twitch after separation which may distract the attacker, and both tails and limbs can be regenerated.

Adult frogs are unable to regrow limbs but tadpoles can do so.
