Right, we have nocturnal & crepuscular for animals that are active at night and dawn/dusk respectively. But what about animals that are active during the day? Or at any time? Is there a word?

Yes. Isn't that what diurnal means?

Crepuscular. That's an interesting word that I've not come across before. Do you want some ointment on that?

Yup, diurnal is the word.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!

Ah yes, diurnal for active anytime. But what about those that are only active during the day?

Where did you get a definition that said active anytime?  All the primary definitions for it that I found say activity during daylight.

Diurnal can also refer to daily cycles, and so cover 24 hours, but being a cycle implies change during the period of the cycle (otherwise it's not cyclic but constant).  Diurnal, in this sense, could therefore be applied to nocturnal and crepuscular types as well, as they too are daily cycles; it's just that their high-points do not occur during daylight.

LeeE - so how does that differentiate between those species active during daylight and those active all the time?

(I got the definition from an aninmal site)

Umm... I would say that those animals active all the time have no cycle, as there is no periodic variation in their activity.

Non-cyclic diurnalism is a bit of a mouthful but does sound very scientific [:D]

Should it be 'non-cyclic' or 'non-cyclical?

I'm honestly not sure, but if we're going to do it, we should do it right [;D]

Non-cyclical sounds more scientific.

 Diurnal

The opposite is of Nocturnal is (Diurnal) ` meaning happening by day, coming out during the day, occurring every day'. Also animals which come out at twilight are called (Crepuscular).
