The publishing information states: © 2025. Published by The Company of Biologists | Journal of Experimental Biology (2025) 228, jeb249258. doi:10.1242/jeb.249258 and the first sentence of the Abstract reads, 'Seals can detect extremely weak water disturbances with their highly sensitive vibrissae'.

Seals' whiskers are incredibly sensitive to fish wakes & other water movements & now it turns out that seals can probably tell in which direction a fish is escaping by sensing the vortices sent spinning off by the fleeing fish with their whiskers

Screenshot of the PDF of the Research Article Penguin molt revisited: dive performance following the molt of adult king penguins (Aptenodytes patagonicus) and conflicting physiological demands at sea by Enstipp et al. The publishing information states: © 2025. Published by The Company of Biologists | Journal of Experimental Biology (2025) 228, jeb251141. doi:10.1242/jeb.251141. The first sentence of the Abstract states: The annual molt, when penguins replace their entire plumage within a short period while fasting ashore, is the energetically most challenging period of their annual cycle.

Unlike other birds, penguins moult all their feathers at once. In their recent article, Enstipp & co show that, while this moult might be more costly for juveniles, adult king penguins still pay a price for keeping their plumage perfect
