World’s smallest frog can’t jump at all!

 Scientists found the tiniest vertebrate1 in the world! It’s called the Brazilian flea toad2. However, here’s the funny thing—it’s not actually a toad or a flea, but a special kind of frog that lives on a few hills in Brazil.

 Male Brazilian flea toads are only about 7 millimeters long and females are about 8 millimeters. One could easily sit on the tip of your finger.

 Being so small, their bodies look a bit different compared to those of other frogs. While most frogs have five toes on their back legs and four toes on their front legs, these little frogs only have two toes.

 They also can’t jump like a flea. A study in 2022 found that when they try to jump, they lose their balance3! They’re just so small that their bodies aren’t good at helping them stay balanced.

 Scientists believe that there are still many other mini “surprises” waiting to be found out there in the world. And anything smaller than six millimeters long would teach us a lot about how animals’ bodies work.
