: This kinda confirms what I thought - I've got both helena and radiata and thought these guys looked very similar both in their markings, dimensions and general behaviour.

: I like this group a lot. Is there any close connection with the taeniura group as these guys often seem like somewhat smaller versions of e.t spp?

: I have a ridleyi which displays many of the same defensive postures as my radiata. S- bend neck, neckspreading and wide open mouth.

: Thanks for the input.

I think there's probably some connection between taeniura and the radiata group, but not as close as the sps. in the radiata group are to each other. That's just my opinion. I think someday the radiata sps complex will probably get a different genus name, then it's a contest to see if taeniura will go with them, stay in Elaphe, or get a genus of its own :)

PS: Check out the way helena and radiata can inflate their necks. This is what Gonyosoma oxycephala does too, and this species has a special air sack which it inflates. I wonder if radiata and helena have that air sack adaptation??
