Robert Clarence Irwin Instagram – Crocodile number 251 in our groundbreaking research study, we named ‘Captain America’. He was a challenge to catch and full of energy non-stop… it seemed like he could do this all day. But we were able to successfully attach a tracker, on his flank… on your left. Now we can see where he goes and what he gets up to, in order to learn more about this elusive species… thanks to incredible telemetry technology, we’ll be with him to the end of the line.
