Oceans

Kevin Lafferty emerges from the waters off Anacapa Island near Ventura, California, after spearing fish in March 2018. He’s advising a UCSB PhD student on research to determine if reef fish inside protected marine reserves have more or fewer parasites than depleted fish populations outside the reserve. It’s to test a pattern that has emerged in other studies: that parasites thrive with richness and abundance of marine life.

In Praise of Parasites

They worm into snails and infect the brains of fish. They’re also examples of sophisticated evolution and keys to ecosystem balance.

Princepajaro, a male California sea lion, swims in a pool during treatment for leptospirosis at The Marine Mammal Center in Sausalito, CA. When a leptospirosis outbreak occurs, the Center’s scientists study the disease to learn more about what causes an outbreak and how we can improve treatment for infected animals.

Major Disease Outbreak Strikes California Sea Lions

Leptospirosis afflicts sea lions on a semi-regular cycle, but warming waters and migrating fish could make the marine mammals more susceptible
