Optional Field Trip 2 - Night Lighting

Our second optional field trip was on Monday night, Sept. 12th. We held two flashlights over the MBL dock in Eel Pond. Highlights included collecting 2 of only 3 Mnemiopsis ctenophores observed and a ?larval horseshoe crab. We mainly observed small crustacean zooplankton, and it is likely that most were copepods and some were gammarid amphiopods. We also spotted some caprellid amphipods and captured a shrimp. In terms of chordates... we collected and released a pipefish and saw other very translucent juvenile and possibly larval fish.
