And finally; the reason many divers choose to visit Richelieu Rock are the whale shark and manta ray visitations. Kings of the sea they glide along without rivals, filtering huge amounts of water, feasting on the plankton blooms. These magnificent creatures are regularly viewed at Richelieu during high season.
Unfortunately, whale sharks are an endangered species. More research & action is needed to monitor their migrations & prevent extinction before it's too late.
