Carinascincus ocellatus, the spotted (or ocellated) snow (or cool-) skink is very small and inconspicuous and hangs out on an out-of-the-way island — Tasmania, way down south — but offers two excellent things for us to enjoy:
— the name spotted snow skink, an /s/-alliterative double trochee (SW SW) that lends itself to satisfying repetition as a found mantra
— the occasional individual that’s sexually discordant — of one sex anatomically (and reproductively), but the other sex genetically (for these skinks, anatomically male but genetically female); the change in anatomical sex during incubation (for these skinks, associated with temperature then) is attested in some oviparous (egg-laying) fish, amphibians, and reptiles, but not, until recently, in a viviparous (live-bearing) creature. Most lizards are oviparous, but Carinascincus ocellatus is viviparous, so it’s a new frontier in sexual discordance.
There turns out to be quite a lot to say about this little creature; bear with me as I wander, pretty much aimlessly, over a large intellectual landscape.
