[2][3] The longnose skate was briefly associated with the genus Beringraja, having been previously included in Raja until genetic evidence supported reclassification.

[2][1] The longnose skate has an elongated snout and deeply notched pelvic fins.

[9] The age estimates are based on counting growth bands in vertebrae, a method which has been validated using bomb radiocarbon.

[10] In a recent study published in August 2019, researchers found that this nearshore species tends to dwell in the upper continental slope in highly sedimented areas, and also in association with rock out crops, authigenic carbonate crust, and mixed substrate areas in depths between 200 and 929 m. Longnoses inhabited areas with 3–6 °C temperatures.

This research came from the first long-scale, long-term assessment of skates in deepwater of the eastern North Pacific.
