Some things are too cool to wait until Friday for the TGIF tag. Check out this spectacular footage of male Torquigener sp. pufferfish in Japan, making nests to attract females. Thats one of the most exquisite bits of fish behaviour I’ve ever seen. Role over to Nature for the original paper, and to Discover magazine for a nice article
I remember seeing the photos of this phenomenon last year. The video is great!
