What characteristic defines Eunectes notaeus within Kingdom Animalia?

Answer

It must consume organic matter for energy (heterotrophic)

Membership in the Kingdom Animalia signifies that an organism is multicellular, eukaryotic, lacks cell walls, and critically, must obtain energy by consuming other organic matter, which defines it as heterotrophic. While possession of a notochord relates to its Phylum (Chordata), and kinetic skulls relate to its Order (Squamata), the fundamental characteristic placing it in Animalia relates to its nutritional mode—being a consumer rather than a producer like plants.
