Amazing facts about creatures big and small
Male platypuses have sharp venomous spurs on their hind legs that deliver excruciating pain to humans. The venom is only produced during breeding season and causes swelling that can last for months.
A tiny Japanese pufferfish creates intricate circular patterns in the seafloor sand that span about 7 feet in diameter. The male spends 10 days making this elaborate sculpture entirely to attract a female.
Meerkats take turns acting as sentinels, standing guard on high ground while the rest of the group forages. The lookout gives specific alarm calls for different predators — one for hawks, another for snakes, another for land predators.
Hippos secrete a reddish oily fluid from their skin that acts as natural sunscreen and antibacterial protection. This 'blood sweat' gave rise to old myths that hippos sweat blood.
New Caledonian crows craft and use tools to extract insects from bark, and some individuals have been observed making hooks out of twigs. Young crows learn tool-making by watching their parents, similar to how humans learn from adults.
Different pods of orca whales have their own unique dialects, hunting techniques, and traditions that are passed down through generations. Some pods eat only fish while others hunt marine mammals — these are considered distinct cultures.
The Arctic tern makes the longest migration of any animal, traveling about 44,000 miles round-trip each year between the Arctic and Antarctica. Over its 30-year lifespan, it flies the equivalent of three trips to the moon and back.
When threatened, sea cucumbers eject their internal organs out through their body wall to distract predators. They can regenerate all of their organs within a few weeks.
A spotted hyena's 'laugh' is not a sign of amusement — it is a complex vocalization used to signal excitement, frustration, or submission to dominant group members. Each hyena's giggle is unique and identifies the individual.
Pangolins are the only mammals covered in scales, which are made of keratin — the same material as human fingernails. When threatened, they curl into a tight ball and their sharp scale edges make them extremely difficult for predators to unroll.
