Brachycephalus ephippium, commonly known as the pumpkin toadlet, is a small frog species native to the neotropical rainforests along Brazil’s Atlantic coast. Despite their name, these creatures are neither pumpkins nor toads.
The pumpkin toadlet is incredibly tiny, comparable in size to a chickpea when fully grown. This miniature size provides both benefits and challenges. Their small stature allows them to evade predators easily. However, it also results in some anatomical limitations. The toadlet’s inner ear is so minute that it is not fully developed, affecting its coordination and movement. As a result, their jumping appears erratic.
Atlantic science writer Katie Wu explores this peculiar aspect. She questions if a frog that doesn’t jump well can still be considered a frog. Her insights reveal more about these unusual creatures’ lives and characteristics.
The discussion was part of a podcast episode produced by Rebecca Ramirez, with editorial input from Gabriel Spitzer and fact-checking by Rachel Carlson. For visual enthusiasts, a video provided by the Florida Museum displays the quirky way pumpkin toadlets move.
