Our second lesson in the Everblue At-Home Education series highlights groundbreaking research from Dr. Kelly Sutherland on salps! A salp is a gelatinous floating animal that lives in the open ocean. Salps and their relatives, pyrosomes, have recently become of great interest in the news, since new climate conditions have allowed them to bloom in large numbers, particularly off of the Pacific Northwest coast of the United States.

Dr. Sutherland is a professor at the University of Oregon. She specializes in marine biomechanics, or how the biology of living organisms interacts with fluid dynamics of the ocean. 

Click on the links below to see how salps move in their liquid ocean home!

1. Watch members of a salp chain swim together! Each salp contracts to squirt out water and propel the colony forward. This is jet propulsion in action! The green stuff is a fluorescent dye used to see fluid motion.


2. See how a solitary salp swims!
