Simalia amethistina (Schneider, 1801)

Species Common Name & Initial Size Claim

This species, Simalia amethistina, commonly known as the amethystine python, has been reported to reach total lengths over 5.5 m (18.0 ft), including the tail.

Size Claim Clarification

This size report is likely a result of confusion with the Australian species Simalia kinghorni, as even 4 m (13 ft) specimens of S. amethistina are already considered extremely large.

While the amethystine python is smaller than the Australian scrub python (S. kinghorni), some sources state that S. amethistina can reach lengths of 6 m (20 ft), with weights up to 27 kg (60 lb), and possibly even 30 kg (66 lb).

Its smooth dorsal scales are arranged in 39 to 53 rows at midbody, and deep heat-sensing pits are present on six or seven of the posterior lower labials.
