![]() ![]() From as little as £2, you can help us create a future where both people and the planet thrive. No matter the size, every gift to the Museum is critical to our 300 scientists' work in understanding and protecting the natural world. We are a charity and we rely on your support. Understanding and protecting life on our planet is the greatest scientific challenge of our age. To reverse the damage we've done and protect the future, we need the knowledge that comes from scientific discovery. People tell us they 'still get shivers walking through the front door', and thank us for inspiring the next generation of scientists. We must act on scientific evidence, we must act together, and we must act now.įor many, the Natural History Museum is a place that inspires learning, gives purpose and provides hope. But if we don't look after nature, nature can't look after us. This is the first time in Earth's history that a single species - humanity - has brought such disaster upon the natural world. Climate change is creating deserts and dead zones, and hunting is driving many species to the brink of extinction. Pollution has caused toxic air in our cities, and farming and logging have wreaked havoc on our forests. Our future depends on nature, but we are not doing enough to protect our life support system. Now we're wondering if you can help us.Įvery year, more people are reading our articles to learn about the challenges facing the natural world. or that it helped you learn something new. Green anacondas demonstrate the biggest size gap among terrestrial vertebrates: While males can reach an average length of about 10 feet, females can grow to be more than 17 feet and perhaps up to 25 feet long. The difference in appearance between males and females of the same species is called sexual dimorphism. Male and female anacondas show the biggest size difference on Earth. The lower jaw adds another two rows for extra grip. ![]() Like most snakes, anacondas have four rows of teeth on their upper jaws.įour parallel lines of backwards-pointing teeth help serpents grasp their prey and swallow it whole. Despite their enormous size and strength, anacondas often sustain significant injuries while hunting caimans. The numerous species of caiman range in length from about 5 feet to 13 feet, making them formidable prey for anacondas. Green anacondas won’t say no to snacking on other big reptiles.Ĭaimans are alligator-like aquatic reptiles native to South American rivers. Capybaras frequently weigh up to 140 pounds and constitute one of the snakes’ chief meals. They’ll even consume animals as large as peccaries (a type of wild pig), tapirs, deer, and sheep. Green anacondas will eat almost anything, including birds and their eggs, other reptiles and amphibians, fish, and mammals. Then, they lunge, catch the prey in their jaws, and wind their incredibly muscular bodies around the animal until it suffocates or dies from being crushed. Instead, the lie in wait for an unsuspecting mammal, fish, or amphibian to wander within reach. Like other boas, anacondas lack venom with which to neutralize their prey. Large anacondas often weigh more than 200 pounds, but the longest snake on Earth is the reticulated python ( Python reticulatus). The green anaconda is the world’s heaviest snake, but not the longest. The most likely outcome is that the anaconda would grab the inland taipan by the head or body and then crush it before swallowing it whole. Green anacondas may be on there way to becoming established as an invasive species in parts of southern Florida like its boa cousin, the Burmese python. The size difference, in this case, would result in the anaconda being able to bite, constrict, drown, or use all three methods to kill the much smaller snake. The biggest and best known are the green anacondas, which live live in wetlands and river basins through tropical South America, including parts of Brazil, Colombia, Venezuela, Guyana, Surinam, Bolivia, Peru, and Ecuador. beniensis), and the dark-spotted anaconda ( E. There are four species of anaconda today: Green anacondas ( Eunectes murinus), yellow anacondas ( E. Anacondas are members of the boa family.Īnacondas belong to Boinae, the family of large, non-venomous snakes collectively called boas. Read on for more gripping facts about these massive snakes. ![]() But you may not know that they give birth to live young and can stay underwater for up to 10 minutes on a single breath. Most people know that green anacondas are huge. ![]()
