To investigate scavenging communities associated with carcasses of animals from the water column, we performed experimental food fall studies. We deployed baited camera landers with squid (Loligo vulgaris) and jellyfish (Periphylla periphylla) for 13-35 hours at ~2500 m depth in the Fram Strait at the deep sea Long Term Observatory HAUSGARTEN. The dataset includes all raw count data of scavengers on the food falls sorted by taxon based on image analysis annotation in BIIGLE. Scavengers included Eurythenes gryllus , Scopelocheirus and stegocephalid amphipods, various crustaceans and the gastropod Mohnia.
