Red kan­ga­roo

World of Animals - - Wild Record Breakers -

An adult male red kan­ga­roo, to­day’s largest mar­su­pial, can weigh as much as

90.7 kilo­grams (200 pounds), yet they’re sur­pris­ingly swift, able to out­pace a race­horse when trav­el­ling at full pelt. They can achieve this thanks to the su­per-ef­fi­cient method of lo­co­mo­tion they’ve evolved to get around. The fur­thest sin­gle leap that has been re­ported is 12.8 me­tres (42 feet) and its high­est jump is noted as three me­tres (9.8 feet)!

“Ten­dons in the kan­ga­roo’s back legs work like

springs, stor­ing and re­leas­ing en­ergy”

Tail The pronghorn would beat a chee­tah in a longdis­tance race. This North Amer­i­canun­gu­late has main­tained 56kph (35mph) over 6km (3.7mi)!FeetBreath­ing The mus­cu­lar tail has been found not only to pro­vide bal­ance while leap­ing but also acts as a third leg to pro­pel the ’roo for­ward. Huge hind feet max­imise take­off power as well as pro­vid­ing a steady land­ing. An added bonus of hop­ping is that the mo­tion nat­u­rally pulls down the di­aphragm, mean­ing air is ef­fort­lessly drawn into the lungs – a process called ‘in­spi­ra­tion’.legs Elon­gated ten­dons in the kan­ga­roo’s back legs work like springs, stor­ing and re­leas­ing en­ergy with each hop, with barely any mus­cu­lar ex­er­tion re­quired.
