A Sea Hare (Aplysia sp.) - neuroscientists favourite subject. It's neurons are as big as 1mm & it has learning capabilities & remembers things as well! Cool beans!!!
I found a moth in almost every cubicle of the ....ahem...lavatory, and was determined to capture them hibernating....they came as weird as they can be!
'Brown Cow's' 4WD had problems & we stopped at an R&R area until my highway toilet break became an adventure on its own.....this tiny 2.5cm moth was resting on the beam of the ceiling!
