In captivity

Aspidelaps scutatus can survive between 20 and 28 years in captivity, though this age is normally not attained in the wild due to predation, accidents, etc.

Venom

The species Aspidelaps scutatus is highly venomous, and its bite has caused at least one reported death of a human, despite its propensity to bite being somewhat low. The venom is highly neurotoxic. Symptoms include slurred speech, ptosis, and partial paralysis. No antivenin is available for this species.

Aspidelaps scutatus preys upon suitably sized amphibians, lizards, snakes, and mammals.

Reproduction

Aspidelaps scutatus is oviparous. Clutch size is 4–10 eggs, and the female may stay with her eggs, coiled around them.

Subspecies

Three subspecies are recognized as being valid, including the nominotypical subspecies.
  • Aspidelaps scutatus fulafulus
  • Aspidelaps scutatus intermedius
  • Aspidelaps scutatus scutatus
Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Aspidelaps.
