Curious Grey Seals

Halichoerus grypus


It is a large seal, with bulls reaching 2.5–3.3 m long and weighing 170–310 kg ; the cows are much smaller, typically 1.6–2.0 m long and 100–190 kg in weight. Individuals from the western Atlantic are often much larger, males reaching 400 kg and females weighing up to 250 kg. It is distinguished from the harbor seal by its straight head profile, nostrils set well apart, and fewer spots on its body. Bull Greys have larger noses and a less curved profile than common seal bulls. Males are generally darker than females, with lighter patches and often scarring around the neck. Females are silver grey to brown with dark patches.


When we approach with our boat, they come to us, to see what's happening!
