[4] The type locality given is "probably collected on the island of Marajo at the mouth of the Amazon".

[3] Eunectes deschauenseei is found in South America, in northern Brazil (the Pará and Amapá states) and French Guiana.

[1][4] E. deschauenseei is a semi-aquatic species usually found in swampy, seasonally flooded freshwater areas at elevations below 300 m (980 ft).

[7] The savanna habitat of E. deschauenseei is highly threatened by agricultural expansion, but the threat posed on this species is not known.
