Blue Poison Dart Frogs
16 Answers
I saw these at the zoo a couple of weeks ago and was just having a little read about them online because I think they're fantastic and discovered they actually are not found in water I'd sort assumed they were blue because that was perhaps some sort of water camoflage (although admittedly though that seemed a bit ridiculous unless they were planning on hiding in your average our-door swimming pool) so was just wondering, does anyone know why they're actually blue? I understand certain colours to indicate poison (or not), camoflage or indeed just a bit of prancing around to atttact the ladies... But I don't understand what the significance of the blue is.
Cheers :c)

One of Alfred Hitchcock's pranks once was to stage a banquet but dye all the food blue. Nobody could bring themselves to eat it. Hard to say why, but apparently blue food just looks dangerous.

Given that the blue colour is a warning it would need to stand out against the frog's typical surroundings.
Regarding blue food, it may just be that hardly any human food is naturally blue apart from some berries and we accept them because our parents say they're OK. We are naturally 'suspicious' of unusual things which might kill or harm us.

Not all poison darts are blue, quite a lot of them are black and yellow or orange, orange and blue or blue and black.
I doubt it's camouflage so much as a warning. The different colours may be suited to the colours most visible their main nemesis, as some animals have near or entirely monochromatic vision. Humans have pretty terrible vision in terms of the entire electromagnetic spectrum (it's a hair thin line somewhere in the middle).
The poison in those frogs is actually one of the most toxic chemicals known to man, it's about as lethal as VX nerve gas in terms of the dose. Maitotoxin, from a fish in Thailand, is about 20 times worse and Botulinum Toxin is the worst, at over 2000x stronger than the frog and nerve gas, which is why Liza Minelli's face looks the way it does now.
That aside, they do look incredibly cute and very colourful. They also wake up during the day and go to bed at night, unlike most other froggies.
