A second group worked on the question of whether various hermit
crab species are selective about the shells which they use as "homes."
Day 5 of the NSI trip was devoted to work on group projects for the Marine Ecology course.
Here a group works on the human impact on various crabs species (see below) on the rocky shores
at Polka Point.
A second group worked on the question of whether various hermit
crab species are selective about the shells which they use as "homes."
A third group worked on the distribution of holothurians or sea cucumbers like the
ones below.

A fourth group worked on the orientation of oysters encrusted on
the rocks at Polka Point.
A fifth group worked on the stratification of the intertidal zone by various snail species.
A sixth group worked on commensal relations between Haddon's sea anemone and a species of shrimp.
A seventh group worked on soldier crab burrowing rates for various substrates.
