one thing for sure i can tell you... back when i was able to scuba dive, i went on a shark feed in the Bahamas even though i had ALWAYS said i would NEVER do that and i swear while we were down there all the sharks were communicating with me and i understood they wanted me to leave so i was one of the 1st divers to head back to the boat. :)

seriously, it was a fun dive that i enjoyed a bunch but i would never do it again. LOL

it was mainly nurse sharks and reef sharks but with some of them bigger than i was, to me it was scary. the divemaster from Blackbeard's, the sailboat we were on was the one feeding them and it was frozen fish that they had caught. i took some pics but unfortunately the quality isnt that great.

thanks for making this thread, its pretty interesting.
sharks have the abilitly to sense fear from a decent distance, i want to say its electrolytes or electro something or other that is released when something displays fear and the can sense it. ( not sure if its electrolytes or whatever but its something like that) and as im sure many of you are aware they can smell a drop of blood in the water. they also are attracked to loud noises/movement.
dolphins, whales make noises communicating. a fish in your tank nipping at another fish is communication, it simply means get away, lol but communication none the less. clownfish "twitch" which ive heard is a sign of dominancy but not sure on that. pistol shrimp pair up with watchman gobies and the shrimp will dig the hole, the goby will keep a look out. when the goby sees danger it flutters its tail and the shrimp returns to the hole. here is communication between 2 different species, pretty amazing.
as for kym saying its amazing that fish can "smell" you should see my tank go wild over 1 squirt of food. the fish go crazy, the corals come to life, nassarious snails emerge from the sand over a drop of food hitting the water so its apparent they have some sort of sense too.
i dont know much on the bubble code theory, lol but a bettas bubble nest as well as flaring is communication.

if you think about it, all animals have some sort of way of communication, wether it be verbal or non-verbal. ever wonder how ants walk in lines? they to are communicating by using their feelers for scents and touch of other friendly ants. pretty crazy stuff.

Steve- Those are great pictures. What a once in a lifetime experience. I'd love to do that one day. The idea of sharks in the water freak me out when I'm surfing. Sitting on a board in the water makes you feel like possible shark chum. Being under water is a whole different ball game. Thanks so much for sharing the pics.

Thats whyI don't go in the ocean. I think its beautiful though. The idea of being around something that sees me as food scares the crap out of me.

Your chances of being involved in a car crash are greater than being attacked by a shark. Of course, if you never step foot in the ocean this would never apply to you!
As for me, I'd rather take my chances with a shark than an oncoming car.
