Sperm whale

[buff]

I just saw a program on T.V that mentioned "Sperm whales exhale before diving to prevent breaking bones at great depth and incredible pressure"

I don't think this is true.

Is it??

Thanks

Well, it sure doesn't make any sense, does it? Any air spaces would collapse less with more air in 'em, thus lessening and not worsening the affects of compression on 'em.
Nope, prima facie it's false.

I do recall reading somewhere that sperm whales can dive to something like 1500ft.

Seems that they can go even deeper than that,they have been tracked at depths greater than a MILE !
