If there’s anything Twitter hashtags are good for it’s sharing cute animal pictures. Over a week ago, the scientists of Twitter started an informal competition to see who could post the most impressive photos of animal junk. #Junkoff was followed by the much less alarming #cuteoff, which encouraged scientists to share their most squee-worthy animal images. As was the case with #junkoff, the hashtag yielded a diverse group of creatures, from huge rodents to lichen-loving micro-organisms. One thing these pictures show is that cuteness knows no bounds.
