The saddleback toads are the family Brachycephalidae /ˈbrækáµ»sɛˈfæláµ»diË?/ in the order Anura. As traditionally defined, the family is often limited to just one genus, Brachycephalus, but it is closely related to Ischnocnema, which therefore is placed in the family in recent treatments.Brachycephalus species are tiny, often yellow frogs that are native to Atlantic Forest in southeastern Brazil. In at least one species, B. ephippium, the bright colours are aposematic, warning potential predators of its toxicity, specifically tetrodotoxin.
Brachycephalus species are very small frogs, up to 1.8Â cm (0.71Â in) in length (mostly around 1Â cm or 0.39Â in), and include the smallest frog in the Southern Hemisphere, Izecksohn's toad (Brachycephalus didactylus). They have only three toes on each foot, and two fingers on each hand. This is in contrast to the usual five toes and four fingers of most frogs.
Brachycephalus species are active during the day, and live in the leaf litter on forest floors. The eggs undergo direct development, hatching into miniature frogs, without a tadpole stage. The eggs are laid on the ground, and covered in soil to protect them from the heat and predators. Their amplexus method is unusual, in that it begins with inguinal amplexus, with the male holding the female around the waist, and then shifts to axillary amplexus, in which the male grips above the female's arms. Most frogs species only use one technique.
Brachycephalus pernix frogs have trouble sensing small changes in rotation, which makes landing jumps difficult, a new study suggests. The frogs can roll, cartwheel or backflip through the air, and then hit the ground on their backs or bellies.

Researchers used CT scans to figure out why these pumpkin toadlets are just no good at jumping. The inner ear system of these frogs is so tiny that they lose balance midair. Fortunately their main survival tactic to avoid being eaten doesn’t involve high-speed getaways, but rather staying in one place and being as unappetizing or as inconspicuous as possible. “They’re not jumping around a lot, and when they do, they’re probably not that worried about landing, because they’re doing it out of desperation,� study co-author Edward Stanley. “They get more benefits from being small than they lose from their inability to stick a landing.� Full story: https://www.floridamuseum.ufl.edu/science/miniature-frogs-set-record-as-first-vertebrates-to-lose-the-ability-to-balance/ A new study looked at ...
Apparently my Wife Michelle had a phobia of being chased by toads. Lol #animals #nature #shorts

A team of researchers recently looked into the faulty gymnastics of these Brachycephalus frogs that are native to Brazil. These frogs are the worst jumpers ever because of the fluid in their ears. They only attempt their horrible jumps to escape predators. #frogs #brazil #frogjump Read more: https://gizmodo.com/tiny-frogs-bad-at-jumping-1849065376 We come from the future. https://gizmodo.com Follow us. https://twitter.com/gizmodo https://instagram.com/gizmodo https://facebook.com/gizmodo
The combination of fluid and tiny hairs in the inner ear help the vertebrate brain interpret an organism’s position in space and provides a sense of balance. Although these vestibular systems evolved hundreds of millions of years ago, some species are no longer able to make good use of them. According to a paper published today (June 15) in Science Advances, pumpkin toadlets (genus Brachycephalus, and they’re actually frogs) from Brazil have evolved to such diminutive size that there isn’t enough of a vestibular signal to keep the amphibians stable while they jump.
