Both juvenile mangrove whiprays I U. granulatus i and cowtail stingrays I P. ater i appear social and are often observed feeding and resting in groups, likely as a predator-avoidance strategy (Kanno et al., 2019; Martins et al., 2020a, 2020b).

Here we present the first records of voluntary active sound production in the wild by three individuals of two species of stingray: the mangrove whipray I Urogymnus granulatus i (Figure 1b) and the cowtail stingray I Pastinachus ater i (Figure 1c). Similarly, in some shark species an unexpected sound or the sudden increased intensity of a sound can result in rapid withdrawal from the sound source (Klimley & Myrberg, 1979; Myrberg, 2001; Myrberg et al., 1978).
