We all have a common notion that asserts one can’t function without a brain, but there’s nature and its stupefying mechanisms to prove us wrong. As much as it is a sheer necessity for humans to think rationally and put our mind to use, we tend to think there can not be creatures that can not live without a brain.<\/span>\u00a0<\/span><\/em><\/p>\n No, we are not talking about the fictional zombies<\/span><\/em>.\u00a0<\/span><\/p>\n We’re talking about real-life animals, marine animals, to be precise. Several animals, including the infamous jellyfish, exist without a brain and still function anyway.\u00a0<\/span><\/p>\n So here’s a question: ‘How do animals without a brain function’? Well, it seems that, to survive, you don’t need a brain (unless you’re a human who has daily chores and a corporate life to attend to). These animals function without a brain since most of them have nerves that react towards stimuli.\u00a0<\/span><\/p>\n That’s okay, but why do these animals not have a brain in the first place? In this post, most animals that you will see are very simple organisms that lack most other organs and not just the brain. <\/span><\/p>\n The major conjecture that we can come to is that these organisms don’t need a brain (that’s it), which is why they abandon the existence of it. One brainless animal, the sea squirt, is originally born with a brain, but it later transforms its bodily composition, eradicating the brain from its body completely.<\/span><\/p>\n Now that you know about it let’s get to the post already and learn more about these animals that have abandoned the brain’s complete existence, something we humans can not go without.\u00a0<\/span><\/p>\n <\/p>\n <\/p>\n A jellyfish is probably the most incredible sea creature with absolutely zilch that makes up for its body composition, except for water. The body of a jellyfish is 95% water, lacking essential organs like the brain, heart, and even blood.\u00a0<\/span><\/p>\n Since they don’t have a distinct brain, as a replacement, they have a set of nerves that extend radially through their body. The nerves act as sensory organs which help the jellyfish to detect touch, light, temperature and respond reflexively to stimuli.<\/span><\/p>\n Jellyfish are generally carnivores who usually feed on plankton, crustaceans, small fish, and even other small or dead jellyfish.<\/span><\/p>\n Read: What Do Jellyfish Eat?<\/a><\/p>\n <\/p>\nJellyfish<\/span><\/h2>\n
