Discussion
- Body length (= tube length) L_w is assumed to be proportional to squared shell length L_s: L_w = L_s^2/ L_M
- shell length L_s is assumed to be proportional to body diameter L_d = L_s*del_M, with del_s = 8.2/11
- Cubed struct length L^3 = del_M*L_d^2*L_w, Wet weight Ww = L^3*(1+f*ome). So L_w = (L^3/L_M/del_M/del_s^2)^(1/2)
- mod_1: more larval data (hatch, birth, settlement, puberty), respiration and growth, length-dry weight
Facts
- a special organ, called the gland of Deshayes, contains symbiotic nitrogen-fixing, cellulase producing bacteria (Teredinibacter turnerae) (Ref: Wiki)
- males start producing sperm when a few cm long; they change into females 8 till 10 weeks after settling (Ref: Wiki)
