Tagging marine animals with sensors to track and study their movements can provide researchers with important environmental and behavioral information, including energy usage, habitat changes, and migration patterns. But existing techniques to attach sensors currently largely rely on invasive physical anchors, suction cups, and rigid glues. While these techniques can be effective for marine animals with hard exoskeletons and large animals such as sharks, the traditional tag attachment methods are not ideal for more fragile species, such as squid and jellyfish.
