Sequence and expression of an a-amylase gene in four related species of
prickleback fishes (Teleostei: Stichaeidae): ontogenetic, dietary, and species-level effects.
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).
South of Point Conception, there's a slight possibility of hooking a dark green California moray; farther north, you may nab a gray, brown, or green wolf-eel (neither has the
prickleback's distinctive knobby forehead).
* Stichaeid and pholid perciforms (
pricklebacks and gunnels) guard their egg masses by curling around them (Qasim, 1957; Hughes, 1986; Coleman, 1992).
Age, length, weight, reproductive cycle, and fecundity of the monkeyface
prickleback (Cebidichthys violaceus).
Bryozoichthys marjorius McPhail 1970--Pearly
Pricklebackcalifornicus appears to cause both immediate behavioral reactions and longer-term debilitation in
prickleback fishes.
Diet and gut morphology in fishes, with special reference to the monkeyface
prickleback, Cebidichthys violaceous (Stichaeidae: Blennioidei).
Many species of the
prickleback family Stichaeidae, including the Rock
Prickleback, Xiphister mucosus, are capable of both aquatic and terrestrial locomotion.

prickleback (Lumpenus sagitta), high cockscomb (Anoplarchus purpurescens), wattled eelpout (Lycodes palearis), Pacific sandfish (Trichodon trichodon), and saddleback gunnel (Pholis ornata).

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.
