Teredo navalis has been found along the west coast of Sweden from the Norwegian border to Klagshamn in the Oresund. Psiloteredo megotara also occurs along the west coast to Molle, in the northern Oresund. Between 1971 and 1975, a study was conducted at the Kristineberg Marine Biology Station on the growth of T. navalis and P. megotara. A negative correlation was noted between the population density of T. navalis and the growth of both T. navalis and P. megotara during this period. At the lowest mean specimen density, 22 per dm², 44 per cent of T. navalis were longer than 10 mm (November 1974) whereas only 5 per cent had reached this length (December 1971) at the highest density, 268 specimens per dm². The mean lengths of P. megotara at the corresponding times were 112 mm and 74 mm, respectively. Over a 10-month period at the Borno Hydrographical Station Xylophaga dorsalis burrows reached a mean length of 21.1 mm and a mean diameter of 7.7 mm.
