Amphiporeia virginiana

Amphiporeia virginiana

Collected: June 2009, at Assateague Island VA. in the surf using an epibenthic sled fitted with a plankton net (365 micrometer mesh) pulled by hand in the surf zone just behind the breakers.

1. These amphipods are restricted to the surf zone along the mid-Atlantic coastline where they can be the dominant animals present. They often swim above the bottom.

2. This appears to be a female carrying yellow/orange eggs in her ventral marsupium. These can be seen through the translucent overlapping brood plates that hold them. The embryos will leave the marsupium as miniature  juvenile amphipods

Collected by: Bill Johnson, Goucher College.
