What shared ecological trait characterizes the Eunectes genus, including E. notaeus?

Answer

Obligate semi-aquatic lifestyle relying on swamps and slow-moving rivers

The genus *Eunectes* groups together the anacondas, and although the Family Boidae contains diverse lifestyles (from terrestrial pythons to arboreal boas), the genus *Eunectes* members share a crucial behavioral adaptation reflected in their classification. They are defined by an obligate semi-aquatic existence. This means they rely heavily on aquatic environments such as swamps, marshes, and slow-moving rivers for essential life functions, including hunting and maintaining proper body temperature (thermoregulation).
