Längd vid första mognad / Storlek / Vikt / Ålder
Könsmognad: Lm ? range ? - ? cm Max length : 50.0 cm TL hane/ej könsbestämd; (Ref. 76971)
Body reddish and with a characteristic elongate worm-like shape. Anterior part covered by a small (up to 2 cm long) reduced helmet-like shell consisting of two triangular-shaped parts (anterior and posterior lobes similar), which is white with light brown periostracum (outermost layer). This shell acts as a wood-boring instrument. The brownish soft worm-like body lies in a calcareous tube up to 60 cm long and 1 cm in diameter.
Inhabits wooden material (logs, pilings, ships, other submerged wooden constructions) from temperate to tropical zones (Ref. 76974). Salinity tolerance: 5-35 parts per mille (Ref. 78117). Considered a pest and an invasive species as it destroys submerged wood (Ref. 76971). Found in intertidal areas in timber (Ref. 75831). Wood borer (Ref. 104365).
Livscykel och parningsbeteende
Könsmognad | Reproduktion | Lek | Ägg | Fekunditet | Larver
Female phase: 8-10 weeks after larval stage; females larviparous, i.e., deposits living larvae instead of eggs; fertilized eggs develop through half of the larval period in the maternal gill chambers. Primary male phase: after 4-6 weeks of larval stage in warm temperatures, up to 6 months in colder temperatures with total length range 2-3 cm and 0.2 body diameter (Ref. 78112). It displays poecilogonony as its reproductive strategy (Ref. 99837).
