ABSTRACT Studies examining the oxygen dependency of embryonic survival, growth, and differentiation have been conducted for decades in a diverse array animal taxa but including only one oviparous snake, viperine water snake Natrix maura . Here, we describe study incubating eggs tiger keelback Rhabdophis tigrinus lateralis (Colubridae) under four conditions, hypoxia (7% 11% O 2 ), normoxia (21% hyperoxia (31% different lengths or at stages incubation. The length hypoxic exposure is important affecting development R. t. , with prolonged retarding growth differentiation, increasing mortality deformity, reducing hatchling size mass, altering body shape relative to normoxic controls. Embryonic keelbacks are most susceptible late development, as revealed by fact that 5‐day 7% reduced embryo mass if it occurred Hyperoxia 31% did not enhance embryos, head width, which slightly differed between hyperoxic hatchlings their siblings. This demonstrates importance avoiding snakes.
