Funny moment when 5 brave frogs climbed on the crocodile’s back to hitchhike across the river and the first frog balanced itself just inches from its jaws.

These brave frogs showed no fear when they hopped onto a caiman’s back so they could do the conga.

Hilarious pictures show the moment the five tree frogs clambered up the reptile’s leg and squeezed together on its back – with the first amphibian balancing just inches from its jaws.

Photographer Tanto Yensen, 36, from Jakarta, captured the images on his Canon EOS 60D when visiting Tangerang in Indonesia.

The small tree frogs, which vary in colour from bright green to brown, can be seen clinging onto each other as they hitch the free ride on the caiman’s back.

The caiman looked a little bemused, but it did not seem to mind its new friends.

Caimans will eat frogs, as well as snails, freshwater crayfish, spiders and small lizards.

The first frog could be seen bravely making the ascent up the caiman’s leg – but the larger reptile did not seem to mind

The frog then hopped down the caiman’s back without incident, prompting the other tree frogs to follow suit

One of the larger tree frogs allowed a smaller bright green frog to clamber onto its back, so it could also climb on the caiman

The final frog could be seen helping one of its friends, by pushing up its back legs so it could hop on the caiman’s back
