Many of us have seen rotted teak. especially decking. it literally becomes sponge like, black or green.

Yup. Seen many a Grand Banks trawler with rotting teak decks especially in corners where the water could lay up. Also many know not the ways of the wily algae\ mould\fungal interactions which may degrade even oily woods over Time.....after all old fallen trees new forests make....
Incidentally Iroko is a reasonably good teak substitute without the weight and sheer cussedness of ipe....
