Methods & Sampling

Researchers snorkeled to the reef crest at Moorea, Frech Polynesia. When at least one Mancinella armigera was observed, a 1 m^2 quadrat was centered on the snail(s) and all the Ceraesignum maximum were counted. Vermetids were classified as alive, recently killed (white tube with no fouling), or old kill (fouled, empty shell). For each site where a Mancinella was observed, a control quadrat was sampled. The control was chosen to be similar with regard to size and general community characteristics (percent coral cover and type of coral present).

Instruments

Diving Mask and Snorkel

Supplied Name: snorkel

Supplied Description:

Researchers snorkeled to the reef crest.

Instrument Type

Generic Name: Diving Mask and Snorkel

Generic Description:

A diving mask (also half mask, dive mask or scuba mask) is an item of diving equipment that allows underwater divers, including, scuba divers, free-divers, and snorkelers to see clearly underwater.

Snorkel: A breathing apparatus for swimmers and surface divers that allows swimming or continuous use of a face mask without lifting the head to breathe, consisting of a tube that curves out of the mouth and extends above the surface of the water.
