whale sharks

[Peter van Treeck]

Dear listers,
During my underwater work in the Red Sea several times a couple of whale
sharks (Rhincodon typus)came near observing us. I am quite sure that
these sharks communicate by deep sounds. Is that commonly known? Any
information would be greatly appreciated.
Cheers  Pit
