Figure S1. Male (upper) and female (lower) Otton frogs. Males had larger forelimbs compared with females.
Figure S2. Jabbing response of an Otton frog. A spine was projected from a pseudothumb and jabbed into an object within the frog's embrace.
Figure S3. Wrestling male Otton frogs on the first observation. The male at the back is jabbing his pseudothumb into the head of his opponent, which is trying to escape the other frog's embrace.
Figure S4. Wrestling male Otton frogs on the second observation. The male in front pounced on the other male and grasped him around the waist (upper). The male in back then fought back by pulling his arms to his chest, as if jabbing his spines into the enemy (lower).
