Looks like the old bore hole of a worm of some sort made in the log and sliced through when sawing; however it's the size of the damn thing - at least 5/8" wide and 4" - 5" long...and I guess it's only that long as the saw blade removed the exit hole, so how long the tunnel origially was, heaven knows (if indeed it was a worm).

There's a longhorn beetle that bores living teak trees, Stromatium barbartum. Not likely a ship worm.

Termites will also attack teak.

But this was a huge tunnel, what kind of a beastie leaves a 5/8" hole?

This, I'm sure is not man-made since the circumferance of the tube in places is 2/3 complete and does not follow a straight track (in three dimensions) - I'm not aware of a boring bit that could have done this a century ago.

One of life's mysteries I suspect...

One like this maybe, a longhorn beetle larva.

It resembles the holes made by Carpenter Bees, except maybe too large in diameter.

Wait a minute ... carpenter BEEs? BEEs? Really? That's just wrong. Are there really such things?

If there are, I'm moving to the arctic. What's next? Rust Maggots?

That'll be the baby then. Not sure what the coin is but looks likely the size is about right. When I looked up the adult size, couldn't see how a larva could be so large in proportion.

We have Deathwatch beetle in the house, but their holes seem comensurate with the size of the adults...

The coin is a US penny. The diameter is 19mm, 3/4-inch.

And they don't mind eating pressure-treated lumber, either. I'm not sure what will kill them, aside from brute force.
