Good to see the interest here in Diadophis.
Im not trying to 1-up the fish eater; this is the 1st time Ive heard of that behavior & I've read the majority of the papers published on this taxon. Diadophis appears to have the greatest dietary range of any serpent in N. America. It also has one of the greatest ecological distributions in terms of its habitat. Its a testimony to their nearly perfect design that they have not radiated into multiple species.... tho I still assert regalis really is its own beast.
Anyway I have a jpg if anyone wants to post it (I'm tired of learning new tricks!)of one of my regalis envenomating & consuming a luckless rock boa I found injured by a car.
Cheers, jg
