The giant sand is a giant insect living in New Zealand, belonging to the family Orthoptera. It is one of the largest insects known at present, with an adult body length of 8-10cm and a weight of up to 80g. It has barely evolved in nearly 0.2 billion years, and its shape and features have been preserved to this day. It lives mainly on Little Barrier Island in New Zealand and several isolated islands around it. Due to the lack of large predators on these islands, they were able to evolve into huge body sizes. It is a nocturnal insect that feeds on plants, small insects and fruits. Although large, but generally do not take the initiative to attack humans, only when threatened to defend themselves

Also known as the Hercules beetle, it is one of the largest and strongest beetles in the world. Known for its enormous size and unique appearance, male individuals typically have a pair of particularly long angular jaws, which can be half of their body length. Mainly distributed in tropical rainforests of Central and South America, it is a nocturnal insect that hides in trees or fallen leaves during the day and comes out to be active at night. The life cycle includes four stages: egg, larva, pupae, and adult. Larvae live underground and feed on decaying wood. After years of growth, they eventually pupate and become adults. The lifespan of adult insects is relatively short, and their main task is reproduction.
