Slovaks are currently living in a fear of this tiny tearaway - whose fearsome fighting skills have seen it dubbed the Kung Fu Guinea Pig.
The pint-sized ninja terrified dog walker Marta Domotorova when it attacked her Hungarian pointer dogs during a stroll on heathland near her Hradok home.
With a series of spinning kicks and leaps the fearless rodent saw off both the hapless hounds as they tried to play with it.
'You looking at me?' The fearsome fish that puts Angry Birds to shame
Forget Angry Birds, this is one angry fish.This tropical jawfish certainly looks like it got out of the wrong side of the bed as it gives the photographer a fearsome look.Yet despite its appearance, the burrowing fish is actually quite timid.

Talk about hare-raising! Ravenous raven takes to the skies... with a rabbit in its beak
A little rabbit suffered a grisly end after this hungry raven snatched it from a field and flew off with it clamped in its beak.
Amateur photographer Bob Sharples took this remarkable picture after he spotted the cruel twist of nature out of the corner of his eye.
Mr Sharples, a retired Royal Naval petty officer, was driving near Marazion Marsh, Cornwall, when he noticed a 'black shape carrying something rather large in its beak'.
He said: 'I turned the car around, grabbed my camera and zoomed in. When I realised what it was, I thought it was pretty amazing
Elephants tussle just yards from terrified tourists on safari
Too close for comfort? African bull elephants fight as safari tourists watch from their 4x4 in Kenya's Amboseli National Park
At close quarters: Ecologist Charles Vanpraet said the rampant males had been near a group of females just moments before the epic fight - putting them on edge
Just showing off: The group of young bachelor African elephants had been making their way through a caravan of parked tourist safari vehicles when the tussling began
Bird's eye view: The tourists had parked up to watch, not realising it would spill over towards the caravan of cars
Fierce: Belgian ecologist Charles Vanpraet said it was 'a very fierce and loud battle which went on for almost an hour' 'It had started on the other side of the road and the tourists parked up to watch, without realising it would spill over towards the caravan of cars.
'I don't think any damage was done to any of the vehicles but it does happen.
'Afterwords everything just calmed down and they all walked off side-by-side as if nothing had happened. There was no love lost.
'The bachelors travel together but really they want to be in a herd with females, and they will compete violently to win the admiration of females after showing they are the strongest.
'But they need each other while they are not in a proper herd, so they make up easily.'
All's well that ends well: Apparently, afterwards they calmed down and they all walked off side-by-side 'as if nothing had happened'
The most disgusting insect on Earth: Vile assassin bug that carries the ants it has killed to ward off enemies
this bug looks like it's made a killing carrying a remarkable number of dead bodies on its back to stop it becoming lunch. As this gruesome picture shows this insect has at least 20 ants on its back which according to scientists confuse potential predators like jumping spiders. The aptly named assassin bug uses the dead bodies, as a defence mechanism to fend off enemies.
Putting your back into it: The assassin bug is caught carrying at least 20 dead ants to fend off potential predators
Heavy lifting: Scientists believe that the bugs use the defence mechanism to enhance their reputation Photographer Hock Ping Guek, from Malaysia, decided to document the amazing camouflage strategy using macro photography. He said: 'These assassin bugs are quite small, less than 1 cm, so the camera I used really comes in handy here as it allows me to go beyond the 1:1 maximum limit of the usual macro lenses without the need for any add-on tubes.
'The behaviour is indeed absolutely fascinating. They prey on ants, inject enzyme into the ant preys and **** the ants dry, then put the dead bodies on their back for camouflage, most likely as a form of defence against other predator like jumping spiders.
On the edge: Assassin bugs kill by injecting their prey with an enzyme and then ****ing out their insides 'I spent about 30 minutes photographing these assassin bugs every time I find one. 'I try to shoot as many shots as I could from many different angles, and pick only a few that I like best in terms of angle, moment, composition etc.' Assassin bugs kill in a rather gruesome way by injecting them with an enzyme and then ****ing out their insides.
Despite their fearsome reputation the insects are actually quite small measuring just 1cm in length.
