What necessary characteristic is confirmed by the designation of *H. platurus* in Kingdom Animalia?
Answer
It is a multicellular organism that must consume other organisms for energy, meaning it is heterotrophic.
Kingdom Animalia is the broadest classification level for this snake, encompassing nearly all macroscopic life forms recognized as animals. The defining feature of membership in this kingdom is that these organisms are multicellular and, critically, they cannot produce their own food internally through processes like photosynthesis. Therefore, *Hydrophis platurus*, like all animals, must obtain energy by ingesting and consuming other organisms, making it heterotrophic. This fundamental requirement separates animals from the Kingdoms Plantae or Fungi.
