Teredora princesae is a species of marine bivalve mollusc in the family Teredinidae, the shipworms.

Like other shipworms, Teredora princesae has an elongated, wormlike body which is completely enclosed in a tunnel it has made in floating or submerged timber.

[2] The life cycle is likely to be similar to other shipworms where the males release their gametes into the water and some of the sperm gets drawn into the burrows of females.

[3] Teredora princesae is found in the western Pacific Ocean at depths down to about 150 metres (490 ft).

The logs are from trees which grew in North America, and that have been carried to Hawaii by the southern branch of the Japanese Current, taking an estimated two years to travel the distance.
