Video: Thirsty insects drink caiman鈥檚 protein-rich tears
Crocodilians can be snappy, but this spectacled caiman (Caiman crocodilus) seems perfectly comfortable to let a bee and a butterfly sip the tears straight from its eyes. For more than 15 minutes, the bee and the butterfly indulged in the protein-rich tipple on a scorching day in December 2013.

De la Rosa did some research and found that although this tear-drinking 鈥渓achryphagous鈥� behaviour has been widely reported by wildlife enthusiasts, it has rarely been seen by biologists. He documented the event in a letter published this month in .
