I found this pretty interesting. Obviously with the proliferation of wearable cameras to capture our every moment, you knew someone was going to put one on an animal at some point.
I'm pretty sure we can learn a lot about all kinds of zoological things utilizing this in the future. As the technology continues to evolve we'll see size and weight of the devices continue to drop. That means we'll probably get a truer picture (pun intended) of what the animal sees & does. Heck, when they get small enough, I'd love to see inside a beehive, follow a mosquito, or let's mount one of these on a Reef Shark and see what's going on.
