All videos were then saved in computer for further analyses. Snails were recorded for 1 hour every 2 days throughout 30-day acclimation experiments using Sony NXCAM camera (AVCHD Progressive MPEG2 SD). All snails were kept at 25 ☌ and a 12h Light:12h Dark photocycle. The locomotor videos were produced by recording the snails’ movement when exposed to different artificial salinity regimes of 13, 23, 33, and 43 PSU. Secondary data: Obtained from raw data (Figures and Tables) Raw (Videos, texts, and images deposited to Mendeley database) Instruments: Sony NXCAM camera (AVCHD Progressive MPEG2 SD), AVS Video Editor v.7.1.2.262, Avidemux v.2.6.12, Spectral Time-Lapse (STL) toolbox, Matlab release R2014a Locomotor response and Adaptive locomotion

Keywordsīiological sciences, Marine Biology, and Ecology attramentaria, that is valuable for further exploration and understanding of the impacts of environmental changes on the physiology and adaptive capacity of living marine molluscs. The locomotor dataset we present are the first reports of locomotor response to salt stress of the snail B. A Linear Mixed-effect Model inference procedure was applied in an attempt to assess the impacts of geographic distribution and genetic composition on the locomotor response to salt stress in the snail B. The data consist of three parts: 1) raw videos recording the locomotion of the snails when exposed to novel artificial salinity regimes in laboratory settings, 2) Spectral Time-Lapse results of movement distance of the snails extracted from the recorded videos, and 3) CO1-gene sequences isolated from individuals collected from four sampling sites. Snails were collected from coastal areas on the eastern and western sides of the North Pacific Ocean. The data were obtained from a series of 30-day experiments on snails acclimated to different salinity regimes.

This article describes the experimental locomotor data used to study the general and adaptive responses to salt stress of the northern Pacific intertidal gastropod Batillaria attramentaria.
