National Geographic explores funny, intense, and macho situations of various animals around the world. Comical moments include trout appearing to sing as they spawn, an elephant seal mom and pup exchanging sweet vocalizations, and otters sliding down snow-covered hills. Then, witness rainforest insects engaged in a feeding frenzy and a baby beluga whale struggling to get back to sea when a low tide strands it onshore. Lastly, explore how bottlenose dolphins bully their females and youngsters, a cobra and a monitor lizard battle over an egg breakfast and white-bellied sea eagles link talons and whirl dramatically through the air as they plummet towards Earth.
