Benthic: The benthic zone of an aquatic system refers to the bottom surface and water directly above it, often out of the reach of sunlight. Commonly, [invertebrates] live here and feed on [detritus].

Limnetic: The limnic zone of an aquatic system is the open water in the middle of a body of water, at a depth where light still penetrates.

Littoral: The littoral zone is the area of an aquatic system where light can penetrate the water all the way to the [substrate]. This is the 'shore' area, often dominated by vegetation rooted in the substrate and emerging from the water (like cattails).

Those are good. Can anyone add anything to explain the relevance to caudates?

To benthic, I would add: Many caudate larvae are benthic, remaining on the bottom surface.
