Spix's Saddleback Toad aka Pumpkin Toadlet (Brachycephalus ephippium), family Brachycephalidae, endemic to Atlantic Rainforest in SE Brazil
Poisonous.
This is the most common of the Saddleback Toads, Brachycephalus spp.
As with other Brachycephalus, they lay a few eggs in moist terrestrial locations, and the young live as tadpoles in the eggs, and then hatch out as froglets.
Adults reach a max. snout vent length of up to 19.7 mm (0.78 in).

Brachycephalus pitanga, the red pumpkin toadlet, is a small and brightly coloured species of anuran in the family Brachycephalidae. It is endemic to Atlantic rainforests in São Paulo state of southeastern Brazil
This red pumpkin toadlet was filmed at Serra do Mar State Park - Santa Virgínia Nucleus. In the images we can see two of his defense behaviors, which is rubbing his paw over his eye and opening his mouth.
A day late because I was both stuck for ideas and unwell yesterday. This morning, my mum told me she dreamt that I had drawn a frog doing a high jump, so thanks to her dreamscape for this one! (it's a pumpkin toadlet because they have a habit of flipping over backwards when they jump because their tiny ear canals mess with their balance!)
Don’t Brachycephalus ‘pumpkin toadlets’ also have bones that glow under UV? and can’t hear their own calls?
Well yes but so do you. All bones fluoresce under UV. But Brachycephalus, sometimes called ‘saddleback toads’ (though they are not true toads), have a large bony structure dorsally that fluoresces through the thin layer of skin when exposed to a strong UV source.
Indeed, they allegedly cannot hear their own calls. But this is paradoxical, because calling is extremely energetically costly, and it is not clear why animals would evolve to continue to call if the call is falling on deaf ears. Currently advanced hypotheses are very unsatisfactory imho, so I rather think that we are missing a key part of the puzzle.
Amphibuary day 12: tiny! Fun fact about pumpkin toadlets- their body is so small, that keeping balance is very hard for them. Pumpkin toadlets are even bad at jumping! I think they’d be good at pole vaulting, though.
Also, pumpkin toadlets are some of the only amphibians (well, really, animals-) to have bones that fluoresce under black light. I drew this guy at a Halloween party cause’ why not?
Today's inktober prompt (Toad) is brought to you by Lesbian day!! So now the toads are gay!
Shoutouts to my friend virgil for suggesting I draw them as pumpkin toads, they fit the halloween theme being pumpkin toads, and apparently these toads can't jump, so they're useless little lesbians <3
