As a general rule, for land animals at least, bright flashy colors are a warning sign that either:
A: “Hey, I’m poisonous!”
For example Coral snakes, Bees and wasps, poison arrow frogs, the bright red hourglass on a black widow spider, etc…
Or B: “Hey, I taste really nasty!”
Ladybugs, Monarch butterflys, fire newts, (I’m taking my Boy Scout Guide’s word for it, I haven’t actually tasted a ladybug recently and have no plans to do so).
But underwater, especially in warm climates, the fish are a riot of colors. Now here’s my point, clown fish, parrot fish, striped darters, all brightly colored, all big, slow, STOOPID, harmless and tasty!
Anybody who’s ever gone snorkeling around Catalina island will tell you about Garabaldi fish. They’re like great big traffic-cone orange loaves of bread that stupidly bumble up to you while your spear fishing.
So, whats the advantage in bieng big, slow, stupid, tasty, harmless and brightly colored?
Just strikes me as an engraved invitation to a passing barracuda.
