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).
Life cycle and mating behavior
परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | Eggs | Fecundity | Larvae
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).
