Frannie told me it was a rebus, but I didn't believe her until she started putting them in. A rebus on a Wednesday!? What does that mean for tomorrow??
But let's get to the fill. I like OCTOPI getting a shout out as 1A: Highly intelligent invertebrates. I gave up eating them when I started seeing surveillance lab videos of an octopus getting out of its own tank at night, traversing - out of water - to another tank to eat fish, and then going back into its own tank again. There's video of them using tools, hiding themselves with large shells, camouflaging themselves in ways that make chameleons look like cheap amateurs... anyway, if you're still reading, and you eat octopus from time to time, stop doing that. Or do it more, maybe, because in a few years they'll probably be rounding us up to work in their prawn and crab hatcheries. They'll use their "55D: Arm of the sea?" to keep order...
Where was I? KIT[TENT]AILS (11D: Plant with fluffy flower spikes)? I didn't know the name, but I think I can picture them. TEMPLETON (46A:"Charlotte's Web" rat)? Didn't remember it, but I like any reference to E. B. White. ASWAN (59A: Egyptian dam site)? Huh. Didn't know that one either.
One that I did know, however, was 70A: The "cetera" of "et cetera." The "cetera" is "the rest." It is not, "so on." If you're going to ask for a translation of Latin, make sure that your answer is the correct translation of Latin, not some idiomatic version of it. That clue/answer made me dislike this puzzle very much. I'd blame the creator, but LISTEN, this puzzle has an editor, and it is that editor's job to check for ERRORS, is it not, and to do so COMPTE[TENT]LY? Maybe we should find an octopus and make it editor of the New York Times crossword puzzle.
