How do seals communicate with each other?

How do seals communicate with each other?

All kinds of seals communicate vocally by making noise with their throat and air. The range, pitch, and variety of these noises, however, are all vast. Weddell seals send out long, low whistles underwater at very high decibel levels, and harbor seals make quiet calls.

Do seals work together?

What do male seals do to female seals?

How does the seals heart respond to diving?

Diving heart rate declined as a function of dive duration. In long dives, grey seals employed extreme bradycardia, with heart rates falling to 4 beats min-1 for extended periods, despite the animal being free to breath at will. This extreme dive response is part of the normal foraging behaviour.

How does the harbor seal communicate?

Harbor seals use their acute sense of smell to find a lost pup. Unlike sea lions, harbor seals rarely vocalize on land except during pupping season or when threatened. They often communicate by slapping the water with their flippers. Underwater, however, seals communicate using a series of eerie sounds.

How do seals mate?

After the pupping season, males initiate true mating behavior by chasing, neck- and flipper-biting, and embracing. When approached, females respond by growling, head-thrusting, and flipper-waving. Copulation usually takes place in the water. A male harbor seal may mate with several females.

Interaction with Other Species. Harbor seals often are found sharing haul-out space with other pinnipeds, such as California sea lions and Northern elephant seals. Harbor seals rarely interact with other species but show aggression if threatened.

What makes a male grey seal more successful in breeding?

Size and fat reserves play an important part in successful breeding. Male seals that can spend more time on land chasing females, and less time feeding at sea, have greater mating success.

How are harbor seals different from other pinnipeds?

Unlike most pinnipeds, adult harbor seals are usually solitary and rarely interact other than to mate. However, they often haul out in loosely organized groups. These groups may include both sexes and all ages. Harbor seals generally do not touch each other when hauled out.

Can a harbor seal fight with a sea lion?

Fighting is rare, except between competing males during the mating season. Harbor seals often are found sharing haul-out space with other pinnipeds, such as California sea lions and Northern elephant seals. Harbor seals rarely interact with other species but show aggression if threatened.
