Blue Whale
EndangeredThe blue whale is the largest known animal to have ever lived on Earth, even bigger than the largest dinosaurs. Despite their massive size, these gentle giants feed almost exclusively on krillโtiny shrimp-like creatures. A single adult blue whale can consume up to 4 tons of krill per day. They are baleen whales, meaning they filter ocean water through fringed plates in their mouths. Blue whales are also among the loudest animals, communicating via low-frequency groans and pulses that can travel hundreds of miles underwater.
King Cobra
VulnerableThe king cobra is the longest venomous snake in the world, capable of reaching lengths of up to 5.8 meters (19 feet). When threatened, it can lift up to a third of its body straight off the ground, flare its iconic hood, and emit a deep, bone-chilling growl. Despite its reputation, the king cobra is generally shy and avoids humans if possible. Its scientific name Ophiophagus means 'snake-eater', referencing its unique diet consisting almost entirely of other snakes.
Green Sea Turtle
EndangeredThe green sea turtle is one of the largest sea turtles and the only herbivorous species among them. They are named not for the color of their shells, but for the greenish color of their subdermal fat, which is stained by their diet of seagrasses and algae. Green sea turtles migrate incredibly long distances between feeding grounds and the nesting beaches where they were born. Their streamlined shells and paddle-like flippers make them exceptionally graceful swimmers.
