Identification confirmed by Terry Gosliner
According to Terry Gosliner :" The specimen is Siphopteron tigrinum. That is very interesting that both S. michaeli and S. tigrinum, which are very similar have now both been found from La Reunion.
They are very similar except on has lines (S. tigrinum) and the other has spots (S. michaeli )."
Rudman feels that S. tigrinum must be a colour form of S. citrinum
Synonymous : (according Worms)
- No other name
Bibliographic data :
Nothing is known about tits diet
The presence of a siphon is not in itself a character of Siphopteron. The main characters of Siphopteron are the "prominent crest" along the midline of the siphon, a reduced number of lateral teeth in the radula and some penial structures.
Found on the undersurface of coral rubble in shallow water of 1-10 m depth
