BRUVs recordings of blacktip reef and lemon sharks in Tetiaroa

There is growing evidence of the important role learning plays in shark foraging, but few studies have examined the relationship between learning and foraging behaviour in free-living settings. We addressed this knowledge gap by experimentally contrasting responses of blacktip reef (Carcharhinus melanopterus) and sicklefin lemon (Negaprion acutidens) sharks to an olfactory-only feeding stimulus – baited remote underwater video stations (BRUVS) – that was either offered repeatedly at the same location or spatially randomized throughout the lagoon of Tetiaroa, French Polynesia. Blacktip reef sharks exhibited behaviour consistent with the hypothesis that cue predictability fosters spatial associative learning, exhibiting increasing relative abundance upon introduction of the cue (MaxN at deployment) and decreasing arrival times as the experiment progressed, whereas sicklefin lemon sharks showed no evidence of varying responses to cue treatment type over time. Accordingly, our findings adva..., , , # BRUVs recordings of blacktip reef and lemon sharks in Tetiaroa

The dataset includes detection data for 2 shark species (blacktip reef, sicklefin lemon) recorded on baited remote underwater video systems (BRUVs) deployed in Tetiaroa, French Polynesia, over the course of 23 days in 2016. For each BRUVs drop (lasting an hour), data are presented in separate rows for lemon and then blacktip sharks.

## Description of the data and file structure

The data file has the following columns.

**File**: The specific drop ID (note again that there are two file IDs per drop; one for lemons and one for blacktips).

**Treatment**: Whether the specific BRUVs occurred at a randomly generated location within Tetiaroa's lagoon ('random'), or a pre-selected (single) location where BRUVs were deployed repeatedly ('repeated').

**Camera:** type of camera used in the BRUVs (for this study, all were mono GoPros).

**Date**: ...
