Catriona colombiana was located on sandy substrate at a depth of 50 feet. Length was 1 cm. Water temperature was 57* degrees F.

Note that a different measuring device was used for water temperature. This device was calibrated and found to provide a true measurement, so it is not necessary to add 4 degrees to find the true temperature as with my other observations. See my notes for details.
