Fig. 1From: Lab and field evaluation of tagging methods for the use of acoustic telemetry to observe sea urchin movement behaviour at ecologically relevant spatio-temporal scalesFour tagging methods evaluated. The method of attachment (fishing line in a, T-bar tag in b and nylon screw in c) is highlighted in green and the acoustic tag is highlighted in yellow on the urchin diagrams to facilitate comparisonsBack to article page
