Which term refers to a former order that included terrestrial carnivorans?

• A. Gastropoda
• B. Gas Exchange
• C. Gill Membranes
• D. Fissipedia

Answer: (D)

The concept being tested is how historical taxonomy divided carnivores by habitat. Fissipedia was used to group terrestrial carnivorans (such as cats, dogs, bears, and related families) separately from marine pinnipeds (seals, sea lions, walruses). It reflects an older classification where “land-dwelling” carnivorans were considered a distinct group, later revised with modern phylogenetics. So, this term best fits a former grouping for land-dwelling carnivorans. The other options don’t fit because they refer to molluscs (Gastropoda) or respiratory concepts (gas exchange, Gill membranes) rather than a historical mammalian arrangement.
