In situ observation of sponge trails suggests common sponge locomotion in the deep central Arctic
Located 10° further north than any sponge ground yet reported, the population, primarily comprising Geodia parva, G. hentscheli and Stelletta rhaphidiophora individuals, covers the great majority of the Langseth Ridge from ∼1,000 m upward, to a shallowest peak of 580 m depth, at very high abundance1...

Located 10° further north than any sponge ground yet reported, the population, primarily comprising Geodia parva, G. hentscheli and Stelletta rhaphidiophora individuals, covers the great majority of the Langseth Ridge from ∼1,000 m upward, to a shallowest peak of 580 m depth, at very high abundance1. Sizes of individual sponges varied, with a median diameter of 17 cm (± 0.10 cm SE, n = 10,839, and IQR 11–25 cm); the maximum diameter observed was 110 cm and the smallest were just over 1 cm. This size range equates to a median wet weight of 1.4 kg (± 0.12 kg SE, n = 10,839; IQR 0.4–5 kg; Figure S1).
