Wide wings? Check!
If you've seen a moth through a window, you'll notice the eerie similarities. If the body were a little less chunky, you wouldn't know the difference (maybe the gills and fishmouth might bother you a bit, but not much).
More seriously, anyone know anything about this fish? It has two pair of pectoral fins which separates it from older fish families, like salmon and trout, but that still leaves a huge number of species to distinguish it from.
I apologise for the glare from the tank. I just noticed it at a sashimi restaurant by the bus stop and had to shoot it.
