But with so many other interesting characteristics, behaviours and habits, we\u2019re on a mission to inflate your knowledge way beyond the basics of this fish.<\/p>\n<p>Allow us to blow you out of the water with some of our favourite must-know pufferfish facts!<\/p>\n<h2 class=\"wp-block-heading\">What exactly are pufferfish?<\/h2>\n<p>Also known as blowfish, balloonfish and sometimes simply as puffers, pufferfish are from a large family of the order <em>Tetraodontidae<\/em>. Broken down, \u2018tetra\u2019 is Greek for four while \u2018odent\u2019 means teeth. Pufferfish are in the company of almost 200 other species within this family.<\/p>\n<p><em>Tetraodontidae<\/em> is one family of the order <em>Tetraodontiformes, <\/em>which also includes the families of porcupinefish (<em>Diodontidae<\/em>) and triggerfish (<em>Balistidae<\/em>).<\/p>\n<h2 class=\"wp-block-heading\">They have an incredible defence mechanism<\/h2>\n<p>Their ability to puff up might be one of the once well-known facts about this fish, but what you might not know is that it\u2019s an incredible defence mechanism they\u2019ve developed. Pufferfish can inflate by either sucking up water or sometimes air into their elastic stomachs, a process known as buccal pumping. This allows them to grow up to four times their normal size. They can only do this for short periods, though, since it requires up to five times more oxygen than normal.<\/p>\n<p>To help them inflate into their spherical shape, pufferfish don\u2019t have any ribs and have developed modified gill muscles to aid the buccal pumping process. The skin on their stomachs also has special fibres in parallel rows to help it stretch out and return to normal size afterwards.<\/p>\n<div class=\"wp-block-spacer\" style=\"height: 20px;\" aria-hidden=\"true\"><\/div>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-100123\" src=\"https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-163014234-1024x680-1.jpg\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" srcset=\"https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-163014234-1024x680-1.jpg 1024w, https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-163014234-300x199-1.jpg 300w, https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-163014234-768x510-1.jpg 768w, https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-163014234.jpg 1257w\" alt=\"\" width=\"1024\" height=\"680\" \/><\/figure>\n<div class=\"wp-block-spacer\" style=\"height: 20px;\" aria-hidden=\"true\"><\/div>\n<h2 class=\"wp-block-heading\">They are very poisonous<\/h2>\n<p>They might not look dangerous, but nearly all pufferfish species have a very powerful neurotoxin called tetrodotoxin, similar to other species such as the blue ringed octopus. This is carried passively, and thanks to a genetic mutation, they\u2019ve developed an immunity to the poison.<\/p>\n<p>Their poisonous nature means that if a predator attempts to attack, it will be fatal for them. As a deterrent to would-be threats, some pufferfish even have spines that become more prominent when they inflate.<\/p>\n<h2 class=\"wp-block-heading\">They aren\u2019t great swimmers<\/h2>\n<p>Like seahorses, pufferfish aren\u2019t actually very good at swimming. In fact, their clumsiness and lack of speed means they often find it difficult to out-swim their predators. This is thought to be the reason why they\u2019ve developed such a good defence mechanism to protect them.<\/p>\n<h2 class=\"wp-block-heading\">Pufferfish live in a variety of different habitats<\/h2>\n<p>Pufferfish are quite a versatile family of fish and as such, they can be found in lots of different habitats.<\/p>\n<p>Most pufferfish prefer warm, marine water, while some species, like the green spotted pufferfish live in brackish waters such as the river systems in South America and South Asia. They can be found across the likes of coastal areas, reefs or open water.<\/p>\n<h2 class=\"wp-block-heading\">In Japan, they eat pufferfish<\/h2>\n<p>Some species of pufferfish, mostly those in the <em>Takifugu<\/em> genus, are seen as a delicacy in Japan. However, extra care must be taken during preparation since the fish is poisonous and serving it wrong could be dangerous. Across Japan, you can often find it served as thin, raw slices of sashimi which has been made safe to eat. Would you try it?<\/p>\n<h2 class=\"wp-block-heading\">They can range massively in size<\/h2>\n<div class=\"wp-block-spacer\" style=\"height: 20px;\" aria-hidden=\"true\"><\/div>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-100124\" src=\"https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-2066521675-1024x683-1.jpg\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" srcset=\"https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-2066521675-1024x683-1.jpg 1024w, https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-2066521675-300x200-1.jpg 300w, https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-2066521675-768x512-1.jpg 768w, https:\/\/neuronicdev.es\/deep-sea-world\/wp-content\/uploads\/2025\/09\/iStock-2066521675.jpg 1253w\" alt=\"\" width=\"1024\" height=\"683\" \/><\/figure>\n<div class=\"wp-block-spacer\" style=\"height: 20px;\" aria-hidden=\"true\"><\/div>\n<p>These curious creatures come in all different sizes, from the smallest pygmy puffer originating in India measuring just 3.5cm (a Guinness World Record!) to the largest Mbu puffer which can grow up to around 60cm.
