Discussion
- Males are assumed to differ from females by {p_Am}
- In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
Facts
- Largest terrestrial arthropod (Ref: Wiki)
- Very powerfull claw when big (Ref: OkaTomi2016)
- Juveniles use shell for housing (till 2-3 yr, with thoracic length 0.5 till 1 cm), but adults don not and harden their abdominal terga by depositing chitin and chalk (Ref: Wiki, EoL)
