However, other fish species that have not been identified as part of the harbor porpoise diet were abundant and ubiquitous in the trawls, including Pacific tomcod (dominant in both river areas), longfin smelt, Spirinchus thaleichthys, and capelin (both dominant in Grand Wash River), and snake prickleback
(dominant in Esker Creek).
For seine and trawl catches, unidentified small flatfish (Pleuronectidae), gadids (Gadidae), pricklebacks
(Stichaeidae), and sculpins (Cottidae) were counted in the total catch, but were not considered separate species for species richness calculations because at least one identifiable species from these taxa was captured; unidentified small snailfish and unidentified small poacher were considered separate species because no identifiable species from the families Liparidae and Agonidae were captured.
average 2 to 3 pounds, but sometimes reach 2 1/2 feet long.

Many species of the prickleback
family Stichaeidae, including the Rock Prickleback
, Xiphister mucosus, are capable of both aquatic and terrestrial locomotion.

The sticheid-pholid group included fish from a variety of families: three spine stickleback (Gasterosteus aculeatus), snake prickleback
(Lumpenus sagitta), high cockscomb (Anoplarchus purpurescens), wattled eelpout (Lycodes palearis), Pacific sandfish (Trichodon trichodon), and saddleback gunnel (Pholis ornata).
1 Plectobranchus evides bluebarred prickleback
From our personal observations in laboratory settings, rapid rotational biting can be elicited in gunnels and pricklebacks
when they are presented with large food items.
Michael Horn, a biology professor at California State University, Fullerton, examined the onshore lives of five species of monkey-faced pricklebacks
- slender, eel-like fishes that live in crevices and holes in shallow rocky areas from the Oregon coast to Baja California.
Other species that may prey on juvenile and adult shrimp include eelpouts, english sole, sand sole, pricklebacks
, giant wrymouths, staghorn sculpins, great sculpins, red rock crabs, and graceful crabs.
