We’ve spent a lot of this series on the bats sharing Aiken County with us. For this last one, we’re zooming out to the full 1,500-species order of Chiroptera worldwide to round up the genuine record-holders — the biggest, smallest, fastest, loudest, and longest-living bats on the planet. None of these live in South Carolina, but every one of them is a real, documented extreme worth knowing about.
World-Record Bats: Questions & Answers
Q: What’s the smallest bat in the world? A: The bumblebee bat, also called Kitti’s hog-nosed bat (Craseonycteris thonglongyai), found only in limestone caves in Thailand and Myanmar. Per Bat Conservation International (BCI), it measures about 1.3 inches from head to rump and weighs less than 2 grams — about as much as a small coin. It’s the undisputed smallest bat, and it’s usually cited as the smallest mammal on Earth by body length — though the tiny Etruscan shrew is actually lighter by weight, so which one counts as “smallest” genuinely depends on which measurement you use.
Q: What’s the largest bat in the world? A: The giant golden-crowned flying fox, native to forests in the Philippines. According to BCI, it can weigh about 3 pounds with a wingspan stretching more than 5 feet from tip to tip — roughly as tall as an average adult. Despite the size, it’s a fruit eater, using sharp eyesight and smell (not echolocation) to find figs and other fruit, and it wraps those massive wings around itself like a sleeping bag while roosting.
Q: What’s the fastest bat? A: The Brazilian (Mexican) free-tailed bat — the same species that roosts in South Carolina attics, as it happens. A widely cited 2009 record from the Guinness Book of World Records, Boston University, and Brown University clocked this species at 99.5 mph in level flight, and a later peer-reviewed 2016 study in Royal Society Open Science confirmed speeds near 100 mph, making it the fastest bat, and arguably the fastest animal on Earth, in powered horizontal flight.
Q: What’s the loudest bat? A: The greater bulldog bat of Central and South America, a fish-hunting species whose actual echolocation calls are fairly quiet. But per BCI, when communicating socially with other bulldog bats, it can scream at up to 140 decibels — comparable to a gunshot report or the noise level on an active aircraft carrier deck, loud enough to cause permanent hearing damage in humans at close range.
Q: Which bat travels the farthest? A: The straw-colored fruit bat of sub-Saharan Africa undertakes a seasonal migration of more than 1,500 miles. Each year between October and December, an estimated 8 million of these bats converge on a single evergreen swamp forest in Zambia’s Kasanka National Park to feed on fruit — a concentration so large that BCI describes it as not just the longest bat migration, but the single largest mammal migration on Earth, outnumbering the individual animals involved in the more famous wildebeest and elephant migrations.
Q: What’s the largest bat colony in the world? A: Bracken Cave, just outside San Antonio, Texas, where more than 15 million Brazilian free-tailed bats gather each summer — the largest bat colony on Earth, per BCI. The nightly emergence is dense enough to resemble a tornado on weather radar, and on a single night, this one colony consumes more than 100 tons of corn earworm moths and other crop pests.
Q: Which bat lives the longest? A: Relative to its size, nothing else in the mammal world comes close to Brandt’s bat. Peer-reviewed longevity research documents a wild Brandt’s bat — weighing about 7 grams, lighter than a couple of paperclips — that survived more than 41 years, roughly eight times longer than its body size would predict. Bats in general live about 3.5 times longer than non-flying mammals of similar size, and no one fully understands why yet.
The Ultimate Superlative
Every record on this list is impressive on its own, but they’re all built on top of one shared superlative: bats are the only mammals on Earth capable of true, sustained, powered flight. Gliding mammals exist — flying squirrels, sugar gliders — but none of them actually fly the way a bat, or a bird, does. Every record-setting speed, size, migration, and colony on this list is only possible because one group of mammals solved flight, and then spent roughly 50 million years since finding every extreme version of what that could mean.
The CK9PS Bottom Line
None of these record-holders are roosting in your attic — but the same order of animal that produced a 41-year-old bat the size of a couple of paperclips, and a colony of 15 million sharing a single Texas cave, is the exact same group of animals doing quiet, unpaid pest control over Aiken County every summer night. That’s worth a little perspective the next time one shows up on your porch at dusk.
Detection before treatment. Every time. And verification before documentation. Every time. It starts with the dog. It lives with the handler. Every time.
