In-air evoked potential audiometry of grey seals (Halichoerus grypus) from the North and Baltic Seas. [PDF]
PLoS ONE, 2014 In-air anthropogenic sound has the potential to affect grey seal (Halichoerus grypus) behaviour and interfere with acoustic communication. In this study, a new method was used to deliver acoustic signals to grey seals as part of an in-air hearing ...

Phocine Distemper Virus: Current Knowledge and Future Directions [PDF]
Viruses, 2014 Phocine distemper virus (PDV) was first recognized in 1988 following a massive epidemic in harbor and grey seals in north-western Europe. Since then, the epidemiology of infection in North Atlantic and Arctic pinnipeds has been investigated.

A novel Orthonairovirus detected in grey seal (<i>Halichoerus grypus</i>). [PDF]
One HealthThe Orthonairovirus genus is currently markedly expanding, with several recently detected species causing febrile disease in humans. Orthonairoviruses have tripartite, negative-sense RNA genomes, with the segments denoted according to size: S, M and L. They infect birds and mammals and are primarily transmitted by ectoparasite vectors such as ticks. In

Underwater audiogram of the grey seal (Halichoerus grypus). [PDF]
Biol OpenABSTRACT The hearing sensitivity of two grey seals (Halichoerus grypus) was measured using a psychophysical staircase method from 0.125 to 64 kHz. Both animals had best hearing sensitivity at 4 kHz (43-44 dB re 1 µPa). Below 4 kHz, hearing thresholds differed.

Assessing seal carcasses potentially subjected to grey seal predation [PDF]
Scientific Reports, 2021 AbstractIn order to conduct an objective evaluation of potential ecological effects of grey seal predation on marine mammals, it is essential to establish a broad knowledge base helping in the thorough identification of such cases during post-mortem examination.

A subfossil half-mandible of a Grey Seal [PDF]
Bijdragen tot de Dierkunde, 1995 The fortuitous discovery, in the collections of the National Museum of Natural History at Leiden, of a probably subfossil right half-mandible of a Grey Seal is reported. A short description of the piece is given and it is compared with some other recent, subfossil and fossil material.
