Anomalocaris and Opabinia

Again, a birthday card for one of my brothers. We are both trained biology teachers (although he is the only one working as one) and have had a fascination for prehistoric animals for a long time. About 15 years ago we had an educational CD called "l'Océan des Origines", with very cool (at the time, now they look very dated) 3D animations of extinct species in their environment. The earliest one featured Burgess fauna creatures, including an Anomalocaris capturing an Opabinia. Here's my own take on this now classic theme.
