Identificaciones de pau_y_matias

Observed and photographed by my colleague Mike Morrison. A rare find usually associated with deep water in the tropics. This specimen was 3 m in length, 300 mm from spine to belly and 75-100mm thick and was estimated to weigh around 50 kg.

On my 3rd day working on this project a I recorded a group of around 20 to 30 juveniles Whiprays resting under a Mangrove tree's shade at high tide.

I spent a couple of hours in the water with them being very still until they seemed to got used to the click on my shutter, some were less shy than others and were happy to be very very close to the camera.

I uploaded a video of the sounds made here:
