Abstract To understand the mechanisms that allow
tadpoles of the African clawed frog Xenopus laevis to
develop under conditions of impaired convective trans-
port (hemoglobin poisoning with carbon monoxide),
whole animal surface area and volume were measured
and bulk oxygen diusion was modeled at four devel-
opmental stages (from initiation of heartbeat to pre-
metamorphic climax). Surface area [8.5 mm2
at stages
Nieuwkoop-Faber (NF) 33±34 to 70.2 mm2
at stages
NF 50±51] and volume (1.8 mm3
at stages NF 33±34 to
35.7 mm3
