Two young Aussie adventurers from Sonrisa (www.sailsonrisa.com) helped us discover this dead thing the other day.
As far as I can tell from Wikipedia it used to be a young white sperm whale. It’s too big to used to be a dwarf or pygmy sperm whale.
It’s been dead for a while, as the skeleton has softened and the tail turned. However, the skin is mostly intact with only a few bird holes. There were no shark bites we could find.
It did indeed stink. Nancy found some spermaceti on the beach. It stunk too.
