Facts
- morphological metamorphosis 18 d after birth at 19.5 C (= settlement) (Ref: CellFena1990)
- sigmoidal growth after settlement probably results from intra-specific competition (Ref: Gros2001)
- anus and mouth open 7 d after settlement (Ref: Gros2001)
- P. lividus are either male or female although hermaphroditism has been observed (Ref: Wiki)
