For the Brava Beach, the main taxa responsible for the similarities between samples were crustaceans of the class Amphipoda, with a similarity percentage of 18% for the samples collected with the grab and of 35% for the samples obtained using the prototype sediment sampler.

For example, the percentage of Amphipoda identified as prey items in the diets of post-metamorphs was much lower for Columbia Torrent Salamanders than for Southern Torrent Salamanders.
Amphipoda dominated both in terms of abundance and number of species followed by Polychaeta.

In laboratory all invertebrates were picked out of the samples under stereoscopic microscope (MBS-10) and were sorted into 10 taxa (Chironomidae, Trichoptera, Amphipoda, Hirudinea, Oligochaeta, Gastropoda, Bivalvia, Ephemeroptera, Ceratopogonidae, and others).
