Comments: The scorched mussel is gonochronistic, having separate sexes. |
Developmental trait (?) | Planktotrophy Spawning References: Siddall SE, (1980). A classification of the genus Perna (Mytlidae). Bulletin of Marine Science 30:858-870. Barber BJ, Fajans JS, Baker SM, & Baker P, (2005). Gametogenesis in the non-native green mussel, Perna viridis, and the native scorched mussel, Branchiodontes exustus, in Tampa Bay, Florida. Journal of Shellfish Research 24:1087-1095. Comments: Brachidontes exustus has two spawning periods in the spring, between March and April and, in the fall, between September and November. The larvae of mytilid mussels appear to quickly develop into veligers followed by pediveligers (competent larvae) within a few weeks. Metamorphosis of the pedivleiger occurs once an appropriate area to settle is encountered. |
