Scientific Name	Common Name	Summary
Pentidotea resecata	Eelgrass isopod	The eelgrass isopod is found on more than just eelgrass. It is also common on kelp, such as the genera Laminaria and Macrocystis. It is best identified by the two-horned tail (technically speaking, by the concave posterior end of the pleotelson).
Pentidotea wosnesenskii	Rockweed isopod	This can be a rather large isopod, most easily found in calm, low-lying areas with rocks and gravel.it varies from dark brown to light green, and runs rather fast, with the typical grabbing abilities of isopods. Once you have found the regular Fucus form, look for the very cryptic coralline algae variety.
