Piling on the pounds – The caterpillar

From the time they hatch until they turn into chrysalises, some caterpillars may increase their weight 10,000 times within 20 days.

Biggest prawn cocktail ever – The blue whale

These massive creatures feast on one of the smallest: krill, a tiny shrimp that lives in gigantic schools in most of the world’s oceans. Blue whales strain the krill through sieves in their mouth and consume around four tonnes of them a day. And helping to ensure no krill escapes, they possess tongues the size of an African elephant.

The trash collector – The tiger shark

With some of the most sophisticated surveillance equipment invented by nature, you’d think tiger sharks would know the difference between a tasty fish and a pair of shoes. Well, apparently not. Items found in their stomachs include shoes, coal, canned salmon, a suit of armour, overcoats and even a pair of deer antlers.


Not as greedy as you think – The pig

Not only are pigs very intelligent, they are far pickier eaters than you would suspect. Unlike horses and sheep (and us), they rarely over eat and actually possess a half more taste buds than we do. Which might explain why they don’t like raw onions.

Greedy & deadly appetite – The vulture

This bird is a serious binge eater, often consuming 20-25% of its bodyweight in one meal. And what a meal it is. Anthrax, botulism, cholera - these pose few problems to the opportunistic vulture who will happily feast on the most rancid of rotting carcasses. Occasionally, the vulture will eat so much it cannot take off - in which case it vomits to lighten the load.

High energy lifestyle – The hummingbird

This tiny bird flaps its wings at an astonishing rate and uses up so much energy doing so - that it needs to eat pretty much every ten minutes. Each day it consumes upwards of two-thirds of its bodyweight, surviving on a high-energy diet of nectar.

Left overs are for wimps – The hyena

Unlike lions who may waste around 40% of their kills, hyenas don’t like leaving leftovers. Helping them do this, they have a digestive system that is so acidic they can digest “the indigestible” including bones, horns, hooves, and even teeth.


Do mice really like cheese?

Answer : It’s certainly a popular myth reinforced by classic cartoons such as Tom & Jerry. But for the record, mice do not really like cheese. Given the choice, they would much prefer something like a nice fruit muesli.

Holy guacamole! I really want to...
