  abstract = {{M}arine megafauna species are affected by a wide range of anthropogenic threats. {T}o evaluate the risk of such threats, species' vulnerability to each threatmust first be determined. {W}e build on the existing threats classification scheme and ranking system of the {I}nternational {U}nion for {C}onservation of {N}ature ({IUCN}) {R}ed {L}ist of {T}hreatened {S}pecies by assessing the vulnerability of 256 marine megafauna species to 23 at-sea threats. {T}he threats we considered included individual fishing gear types, climate-change-related subthreats not previously assessed, and threats associated with coastal impacts and maritime disturbances. {O}ur ratings resulted in 70 species having high vulnerability (v > 0.778 out of 1) to at least 1 threat, primarily drifting longlines, temperature extremes, or fixed gear. {T}hese 3 threats were also considered to have the most severe effects (i.e., steepest population declines). {O}verall, temperature extremes and plastics and other solid waste were rated as affecting the largest proportion of populations. {P}enguins, pinnipeds, and polar bears had the highest vulnerability to temperature extremes. {B}ony fishes had the highest vulnerability to drifting longlines and plastics and other solid waste; pelagic cetaceans to 4 maritime disturbance threats; elasmobranchs to 5 fishing threats; and flying birds to drifting longlines and 2 maritime disturbance threats. {S}irenians and turtles had the highest vulnerability to at least one threat from all 4 categories. {D}espite not necessarily having severe effects for most taxonomic groups, temperature extremes were rated among the top threats for all taxa except bony fishes. {T}he vulnerability scores we provide are an important first step in estimating the risk of threats to marine megafauna. {I}mportantly, they help differentiate scope from severity, which is key to identifying threats that should be prioritized for mitigation.},
