... and so here are a couple of compilations.
The first is Sciencealert's top 10 animal videos for this year. They include a lone porcupine seeing off a pride of 17 (!) lions; an octopus 'walking' on land (which is really really strange: it must take an awful lot of effort to do this, unsupported by water, & to what end?); and - reminiscent of someone slurping down spaghetti - a giant red leech engulfing an even larger earthworm.
Or, if 'cute' is your thing, then try the year's 'top 10 cutest animals in science' from the Washington Post. In a win for video instruction, it seems that marmosets can learn new tricks by watching the instructor on video. I must take a compass with me when walking the dog, so that next time nature calls I can see if he's lining himself up with the earth's magnetic field! But I think the little koala wins on the squee! factor :) (Image credit Reuters/Daniel Munoz)
