II. HABITAT AND
Probably occurs lagoon-wide, however, T. rhabdotus has been recorded
primarily around Jim Island, near Fort Pierce, Florida. This is likely an
effect of sampling effort.
III. LIFE HISTORY AND POPULATION BIOLOGY
Age, Size, Lifespan:
Adults typically grow to 15 cm, approximately 4 inches.
Adult Tubulanus rhabdotus are
considered common in the Indian River Lagoon.
Dispersal of larval Tubulanus rhabdotus is accomplished by
floating/ciliation. Mobility of adults and juveniles of this species occurs by
Tubulanus rhabdotus is
gonochoristic with external outcross fertilization.
IV. PHYSICAL TOLERANCES
Tubulanus rhabdotus is eurythermal.
Tubulanus rhabdotus is euryhaline.
V. COMMUNITY ECOLOGY
The trophic status of larval Tubulanus
rhabdotus is not known, but juveniles and adults of this species are
omnivorous, probably preferring annelids.
Tubulanus rhabdotus is found subtidally to the
low intertidal, protected from wave exposure. Juvenile and adult Tubulanus
rhabdotus occur on oyster reefs and pilings of marinas and docks. Preferred
substrata of Tubulanus rhabdotus include cobble, wood piers, oyster and
