New species of marine roly poly pillbug discovered near Port of Los Angeles

A new research paper published in the open access journal ZooKeys reports on a discovery made during a Los Angeles class fieldtrip—a new species of marine pillbug (Crustacea: Isopoda). While documenting that new species, a second new species of pillbug originally collected 142 years ago by biologists on a wooden sailing ship in Alaska was discovered in a collection room at the Natural History Museum of Los Angeles County (NHM) by researchers Adam Wall and Dr. Regina Wetzer.
The Los Angeles discovery was made during a Loyola Marymount University field trip for an invertebrate zoology lab course taught by NHM researcher Dean Pentcheff. The new species wasn't discovered in one of California's pristine Marine Protected Areas, but a dirty, little, rocky beach at the very southernmost tip of the city of Los Angeles—less than a mile from the busiest port in America. "We discovered it clutching on for dear life to one of the five arms of a common sea star," said Pentcheff. "As soon as we saw this bumpy little guy, we knew it was something special that the researchers at NHM had to see, but my class and I had no idea we were looking at a new species."
This newly discovered marine pillbug (or isopod, as it is known to biologists) is directly related to the terrestrial pillbugs found in backyards. Despite their misleading common name, all pillbugs (including the ones in your backyard) are not insects at all. They are crustaceans specially adapted for living on dry land. Pentcheff knew the strange looking animal was an isopod but needed help learning more. He handed the specimen off to world isopod experts Dr. Regina Wetzer, Associate Curator and Director of the Marine Biodiversity Center, and Adam Wall, Assistant Collections Manager for Crustacea at NHM.
"Once we got the specimen to the Museum, we knew it was something unusual. But it was so small that we couldn't just use a normal light microscope to study it. We had to use a scanning electron microscope," said Adam Wall, lead author of the scientific paper describing the new discovery.
