From sudden shocks and blindsiding attacks to jaw-dropping body slams and bone-rattling collisions, the animal kingdom is full of astonishing ambushes.

From the deepest seas to the tallest mountains, animals prove that when it comes to Mother Nature, there's always an exception to the rule.

Animal conflicts, rebellious assaults and dangerous predators; a pack of lions surrounds a baby elephant; a parade horse reacts to loud noise; fish leap from a river.

The herd rushes to the rescue when a buffalo calf is attacked by a lion; a man and his GoPro stumble into a rattlesnake den.

A French bulldog chases off three black bears in one risky standoff; a kitten finds itself in the middle of heavy traffic; a sea lion with major stamina shows that being out of water won't necessarily save it.

Animals go to extremes to survive when fight-or-flight instincts kick in and anything is possible.

Sneaky creatures commit crazy acts, from macho street brawls to out-of-control collisions and animal escapes.

The animal kingdom's most amazing encounters; a python takes on prey much larger than own size and a fearless goose taunts a gorilla.

A pair of giraffes battle viciously for dominance; a fisherman is caught by feeding alligators; a buffalo tosses a lion like a rag doll.

Strange animal run-ins when a primate interrupts a traffic stop and a serpent joins a massage session.

A photo-bombing predator; a purse-snatching monkey; a parrot throws a tantrum.

Llamas take over the streets in Arizona; an otter dodges a hungry orca; a shark takes its chances with a gang of hippos.

Whether it's out-of-bounds behavior or savage instincts, when animals act out, they're forces to be reckoned with.

The most treacherous animal mistakes; fearsome surprise attacks; bone-crushing collisions; predators in too deep and animals pushed too far.

Things get tricky when animals get up close and personal during daring rescues and close calls.

A whale gets frighteningly close to some kayakers; a day at the pool for a family of bears.

Divers have a close call with a great white shark; a sea lion turns the tables on a Russian fisherman; a snow bunny survives an avalanche.

A great white comes between another shark and its meal; a capuchin monkey touches a power line; a python sinks its teeth into a crocodile.

A black bear chews a woman's kayak; elephants back a motorcyclist into a corner; a crocodile snatches an impala from a group of wild dogs.

A group of fishermen meet a giant anaconda; beach goers witness a massive gathering of sharks; a researcher gets on the wrong side of a moose.

Crazy animal world situations, from out-of-control rampages to dangerous battles and deep-sea encounters.

Put up your dukes -- er, paws -- and prepare to discover epic, bone-shattering clashes between some of the world's deadliest predators. From lions, tigers and bears to meerkats, mongoose and mice, the series features testosterone-induced battles between some of the biggest, baddest and often surprising fighters in the animal kingdom, revealing the extraordinary motivations and strategies that fuel each incredible brawl.

Produced by the team that created BBC's "Planet Earth" series, "The Hunt" explores the relationship between predators and their prey. Sir David Attenborough narrates this documentary while the cameras follow the animals in their natural habitats. With a specific focus on strategy, the hunters are examined in detail -- from their use of the environment to their sharp instincts and physical prowess. On the other side of the fence are the hunted, which use their senses and defense tactics to flee when they feel threatened. Each episode centers on a different habitat, and the last one focuses on the state of the planet.

In the varied forms of veterinary medicine, Dr. Susan Kelleher's practice may be one of the more unusual. Known as Dr. K, she runs South Florida's Broward Avian and Exotics Animal Hospital, and this series follows the staff as it cares for rabbits, ferrets, foxes, fish, birds, reptiles, marsupials, and even primates. As do some other vets, Kelleher thinks domesticating wild animals like monkeys is a bad idea, but that feeling doesn't interfere with her taking care of them: "If it will fit through the door, I'll treat it," she says.
