Other prey encountered at relatively high frequencies in stomachs of summer flounder (%F>1%) were polychaetes,
cumaceans, clam siphons, and ostracods.
The rest of taxa: nauplii larvae, gastrotrichs, kinorhynchs, polychaetes, oligochaetes and
cumaceans exhibited low relative abundances (below 1%) and scarce taxonomic representation.

The three types were ~30 copepods (100-400 [micro]m), 2
cumaceans (~600 [micro]m), and 2 zoea larvae (~1 mm).
Cumaceans and isopods were more important for juveniles, decreasing as predator body size increases (Figure 3).
Although gray whales were commonly seen feeding on benthic amphipods (Ampeliscidae) in the northern Bering Sea during the 1980s (Moore et al., 2000), a dearth of whales feeding there in 2002 (Moore et al., 2003) and recent reports of whales feeding year-round on epibenthic
cumaceans (Diastylidae) offshore near Kodiak (Moore et al., 2007) suggest that gray whales may be altering their foraging habits offshore Alaska.
maclovinus was predominantly feeding on crustaceans, since amphipods, isopods,
cumaceans, and decapods were the most abundant prey found in individuals from 61 to 240mm TL and from 180 to 700mm TL.

cumaceans, nematodes).
Ostracods, copepods, and
cumaceans were found within stomachs from L.
