Occurs at depths between 0 and 10 (till 100) m; Hermaphroditic. Giant nerve cells (ref: Emig1979)
Asexual reproduction is by transverse fission after sufficient gonadic material had been formed. The actinotroch larve swims for about 20 days, settles on the seabed and undergoes a catastrophic metamorphosis in 30 minutes (ref: Wiki)
The analysis assumes that pre- and post-metamorphic stages have the same parameters; this is probably incorrect and model abj probably applies
The assumed life span is probably much too long and the measured reproduction rate much too small
In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
