Salinity Tolerance Data - Gastropods

Salinity tolerance data for oyster drills (gastropods). Each row is an individual animal and each column is a variable. "species" refers to Urosalpinx (Atlantic oyster drill) and Ocenebra (Japanese oyster drill). "salinity" is the exposure salinity in practical salinity units. "duration" is the length of exposure in days. "size" is the shell height in millimeters. "alive" is whether or not the animal survived the salinity exposure. "survival" is a numerical code for "alive" where 1 = alive and 0 = death
