8 largest octopuses ever found around the world

Octopuses are among the most fascinating and mysterious creatures in the ocean. Known for their remarkable intelligence, problem-solving abilities, and incredible camouflage skills, they continue to captivate scientists, divers, and marine enthusiasts alike. Their soft, flexible bodies allow them to squeeze through tiny spaces, escape predators, and explore their underwater world with ease. While many octopus species are small and elusive, hiding in crevices or blending into coral reefs, some grow to truly impressive sizes that defy expectations. These giant octopuses can weigh hundreds of pounds and stretch their arms to astonishing lengths, making them some of the largest and most powerful invertebrates in the sea. From the well-known Giant Pacific Octopus to rare, record-breaking specimens, these creatures demonstrate the ocean’s ability to produce awe-inspiring life forms.In this list, we’ll explore the 10 largest octopuses ever discovered around the world and highlight what makes each of them so unique and unforgettable.The giant Pacific octopus (Enteroctopus dofleini) is the largest octopus species known to science. Living in the cold waters of the North Pacific, it can reach an arm span of nearly 30 feet and weigh over 270 kilos, showcasing remarkable intelligence, problem-solving skills, and unique camouflage abilities for hunting and survival in deep-sea environments.Even average specimens are several metres long, making them one of the most recognisable and studied octopuses across diverse marine ecosystems worldwide.The seven-arm octopus (Haliphron atlanticus) is another species that grows to impressive sizes. Some individuals weigh more than 70 kilos.Found in deep waters, it is not often seen, and much about its behaviour remains a mystery. Males appear to have only seven arms because one is kept hidden for reproduction.Found along the coasts of South America, the southern red octopus can grow up to four feet in length. Its reddish colour makes it easy to spot in rocky habitats, and it plays an important role in local marine ecosystems as both predator and prey. Highly intelligent and adaptable, this octopus uses camouflage, jet propulsion, and problem-solving skills to hunt crustaceans and evade predators, maintaining ecological balance.The Caribbean reef octopus may not reach the size of the Pacific species, but it is still a large and striking animal with impressive adaptability and intelligence. It is best known for its speed and colour-changing ability, which it uses to escape predators and ambush prey with remarkable precision and effectiveness in its vibrant coral reef habitat, blending seamlessly into surroundings, manipulating objects, squeezing through tight crevices, exploring curiously, and displaying complex behaviours rarely seen in other marine invertebrate species.The Māori octopus, also known as Pinnoctopus cordiformis, is native to the coastal waters around Australia and New Zealand. It can grow impressively large, with some individuals reaching up to 3 meters across, and is known for being a powerful and intelligent predator. Because of its size and habitat, the Māori octopus is sometimes caught accidentally in commercial fishing gear, particularly in lobster and crab traps. These incidental catches can impact both the octopus population and the fishing industry, as their strength allows them to damage traps or consume bait and catch.The blanket octopus is famous for its dramatic appearance. Females are much larger than males and can extend long, web-like membranes between their arms, giving them a “blanket” look.While not the heaviest octopus, their size difference between sexes is one of the most extreme in the animal kingdom.A close relative of the giant Pacific octopus, the frilled giant Pacific octopus is distinguished by frill-like folds of skin along its arms.This rare and elusive species can reach an arm span of over 14 feet, making it an impressive sight in the deep sea. Although it inhabits the same cold, northern Pacific waters, it is far less commonly encountered by divers and researchers.The common octopus (Octopus vulgaris) is widely distributed across tropical and temperate oceans around the world. While most individuals remain moderate in size, some grow remarkably large, astonishing divers with their unexpected power. They are admired for their impressive strength, problem-solving intelligence, and ability to adapt swiftly to diverse and changing underwater environments.From the cold waters of the Pacific to tropical coral reefs, octopuses come in all shapes and sizes. Some stay small and elusive, while others become giants of the deep.Studying these species not only reveals how varied ocean life can be but also reminds us of how much is still unknown about the world’s largest and most mysterious octopuses.Also read| Male birds laying eggs: Australian study reveals surprising gender reversal in wild birds
