Ever wondered what’s inside a rattlesnake’s tail?father and son dissectthe deadly reptile to find out
Back home the pair, Phoenix, Arizona, rattled off some facts they discovered about the reptile – like how it can shake its tail 50 times per second for hours on end.
Daniel then dissected the tail of the rattlesnake with a sharp knife, the ‘buttons’ which make up the tail cracking as he cut through them.
The pair discovered much to their surprise that the tail was empty inside,.
The rattling sound is made when two hollow layers of hardened keratin at the end of the tail hit against each other.
A new layer to the tail is added every time the snake sheds its skin, so it is not an accurate measurement of how old a particular reptile is as is often suggested.
There are over 20 species of rattlesnakes which are found in North and South America.source:daikymail.co.uk
