Why is this cayman smiling? (best larger to see his grin)
1) Because he is surrounded by his favourite yellow flowers
2) Because he now has the favourite spot on the sand bank because his main rival was taken out by a jaguar (see the video of Mick Jaguar here: http://news.nationalgeographic.com/news/2013/09/130925-caiman-jaguar-animals-science-video-brazil-attack/). This is actually the same sand bank where that, now famous, attack occurred.
3) He knew his image would be posted on SmugMug and this his is own version of a smug mug
4) Your choice
Sorry for falling behind on commenting, but internet here has been painfully slow, or non-existent, the last couple of days, which is not surprising considering I am on a boat anchored on a river, miles and miles from the nearest town.
