Thanks, I'd used the wrong picture. I've fixed it now (though it may take a while to show up correctly depending on how your browser caches images).
Jellyfish Iron Bert is 97 Aquatic Bert in 2017/1.
I do plan to continue listing the aquatic engines as Aquatic (just as I list "Alien Paxton" as Space Paxton). So far, the only places I've listed individual names instead of group names are the affiliated engines DCSF, SpongeBob and Tootsie (DCSF and Tootsie both reusing engines for different affiliated characters), and Core Moments (because that label is pretty unobvious: I wouldn't expect even a long-time Thomas fan to see a black-and-yellow James and think, "Core Moments!" (though I do sort of regret not using the group name and may change it in the future)).
