Flame Fiddler Crab
The Flame Fiddler Crab is one of the most striking small creatures in the inter-tidal environment.
People tend to notice these crabs more than the other fiddler varietys because they stand out from a distance, and often...
...they are less timid than some of there different colored cousins.
Some local people think they are less scared because birds don't attack them, because they are poisonous to eat. The argument is that being poisonous to predators is the only way they could survive - because the bright red color makes them easy to see.
The argument is that predators have evolved to know that...
... bright red means poisonous.
I don't know whether this is true or not, but I know they are easier to get close to and photograph - so it could be true.
Marine scientists would have ways to test out this...
If anyone knows anything about these hypothesis, that
...Flame Fiddler Crabs (Uca Flammula?) are poisonous...
... and their bright red coloring could be a sign to predators that they are poisonous.
