摘要：
A tracking tag for aquatic animals may detect the occurrence of a predation event. The tag may include a pH sensitive material that degrades in the environment of an animals gut. The degradation of the pH sensitive material causes a change in a detectable characteristic of the tag, which allows the tag to detect the predation event and adjust its operation accordingly.
