Teredo navalis

Linnaeus, 1758


Erling Svensen From yesterdays dive. A big tree down at 35 meter - and quite hairy. The hair was siphons from Teredinidae, and we have three species in Norway that it could be: Teredo navalis, Nototeredo norvegica and Psiloteredo megotara. Do anybody know to see the difference between them. The siphons were aprox 4 - 5 cm long out of the wood.

Bernard Picton I think you'll need the shell. But then you will know what the siphons look like for one at least...

Cynthia D. Trowbridge are those pseudofeces (particles that get ejected before they go through gut)?

Erling Svensen OK. This is from Lysefjord where we dived. So it is quite easy to use the knife and get one..... Thanks Bernard.
