#Brachycephalus pulex

[markscherz]

I heard that the minis have been dethroned as smallest! Is this true?!

Mini were never the smallest frogs, just among the smallest in the world. I myself have described smaller Stumpffia species. But indeed, Brachycephalus pulex seems to have taken the crown for the title of smallest frog in the world, by a small but robust margin. I think it will be some time before this new record is broken.

A Very Tiny Frog

Brazilian flea toad (brachycephalus pulex) How small can a vertebrate get? The Brazilian flea toad (brachycephalus pulex) is the smallest known amphibian and the smallest known vertebrate. Despite its name, it isn’t a flea or a toad but a frog. This very tiny frog is small enough that two of them could sit side-by-side on your pinkie fingernail. From snout to rump, the males average about 7…

The Brazilian flea toad may be the world’s smallest vertebrate

Males measure about seven mm long on average

A Brazilian flea toad’s head is too tiny to bear its many crowns. Scientists have bestowed the frog — which is native to Brazil but is neither a flea nor a toad — with two titles: The world’s smallest known amphibian and smallest known vertebrate. From snout to rump, one Brachycephalus pulex measures just under 6.5 millimeters, herpetologist Mirco Solé and colleagues report February 7 in Zoologica Scripta. That’s roughly half a millimeter shorter than the previous record holder and small enough to sit comfortably on a pinkie fingernail...

Brazilian Flea Toad (Brachycephalus pulex), family Brachycephalidae, found only on a few hills in Bahia, Brazil

A recent (2024) study suggests that this may be the smallest vertebrate animal in the world:

" Measurements of 46 specimens revealed the average male body length to be slightly over 7 mm—making them smaller than a pea—or put another way, two of them could rest comfortably on a pinky fingernail. Females were, on average, 1 millimeter longer. The researchers noted that the smallest specimen they found was just 6.45 millimeters long, which they note is approximately 30% smaller than the previous smallest frog observed..." via: https://phys.org/news/2024-02-flea-toad-world-smallest-vertebrate.html

The World’s Smallest Vertebrate Is a Tiny Brazilian Frog, Study Finds

Adult male Brazilian flea toads are just over 7 millimeters long on average, and females measure about 8.15 millimeters

A tiny frog endemic to the state of Bahia on Brazil’s Atlantic coast may have just earned the title of the smallest vertebrate in the world.

The Brazilian flea toad, or Brachycephalus pulex, was first discovered in 2011—and despite its name, it is technically a frog, not a toad. Researchers immediately suspected the creature could break the record for the tiniest frog—and vertebrate—on Earth, but it wasn’t until a new study that scientists systematically measured the lengths of the species’ males and females.

The male frogs, which are smaller, measured 7.10 millimeters long on average, the team reported this month in the journal Zoologica Scripta. An earlier study of the frog Paedophryne amauensis, the previous record holder, found that its males averaged 7.70 millimeters in length.

“It’s absolutely clear,” Mark Scherz, an evolutionary biologist at the Natural History Museum of Denmark who did not contribute to the findings, tells New Scientist’s Jake Buehler. “These really are potentially the smallest extant frogs in the world, which is astonishing.”

Tiniest vertebrates that we know at the moment: Brachycephalus ephippium (pumpkin toadlet) and Brachycephalus pulex

[dreaming-notsleeping]

Newest contender for the world's smallest vertebrate. The Brazilian flea toad (actually a frog) was first described in 2011 but since them more have been examined. The male is slightly smaller than the female, averaging just over 7mm.

"At such small scales, frogs develop strange anatomical quirks, such as losing toes or having such underdeveloped ears that they can’t hear their own suitors’ songs. Some species can hardly jump because their balance organs are so wee."

Pesquisadores da Uesc descobrem o menor anfíbio do mundo

O menor anfíbio do mundo é baiano. O sapinho pulga, Brachycephalus pulex, é uma espécie encontrada apenas em topos de morro na Reserva Particular do Patrimônio Natural (RPPN) Serra Bonita, em Camacan, e no Parque Nacional Serra das Lontras, em Arataca, ambos no Sul da Bahia. A descoberta foi resultado da pesquisa de mestrado da bióloga Wendy Bolaños, no Programa de Pós-Graduação em Zoologia, da…

Frog Smaller Than a Human Fingernail May Be World’s Smallest Vertebrate

By Spooky on March 1st, 2024 Category: Animals The Brazilian flea frog (Brachycephalus pulex) measures only between 7 and 8 millimeters in length, which likely makes it the smallest vertebrate on Earth. In 2011, Mirco Solé, a researcher at the State University of Santa Cruz in Brazil, discovered the tiny Brazilian flea frog, an amphibian so small that it could comfortably fit on a small coin.…

Какая кроха! Так выглядит самое маленькое позвоночное в мире (фото)

Длина тела крошечного существа не превышает 7 мм.

Ученые из Государственного университета Санта-Крус изучили рекордсмена среди позвоночных — седлоносную жабу Brachycephalus pulex. Представители этого вида встречаются в Бразилии. Они славятся своим миниатюрным размером. Статья о них опубликована в журнале Zoologica Scripta.

Длина тела самцов седлоносной жабы достигает в среднем 7 мм. Самки чуть больше — 8 мм. Изученный экземпляр оказался еще меньше — всего 6,45 мм. Эта кроха спокойно поместится на вашем мизинце.

Рекордно маленький размер находки позволил наделить ее сразу двумя титулами. Жабу признали самой крошечной бесхвостой амфибией, а также самым маленьким позвоночным в мире.

Небольшое тело влияет на развитие аномальных анатомических особенностей представителей Brachycephalus pulex. Например, у них есть проблемы с формированием внутреннего уха и задних конечностей.

Ранее в Эквадоре нашли уникальные виды стеклянных лягушек. Они обладают прозрачным животом, через который можно увидеть сердце, печень и пищеварительную систему.
