Lancelets live in which habitat?

Lancelets live in which habitat?

• A. Pelagic
• B. Benthic
• C. Freshwater
• D. Aerial

Answer: (B)

Understanding habitat categories helps place organisms by where they spend most of their life. Lancelets are marine animals that live buried in the sandy or muddy substrate of shallow coastal waters. This makes them benthic—the bottom-dwelling zone of the sea. They stay close to or within the substrate and filter feed from that position. They are not pelagic, which would mean living in the open water column away from the bottom; they are not freshwater, since they inhabit seawater; and they are not aerial, as they do not live in air. So their habitat is best described as benthic.
