What is a group of Walruses called?

A group of walruses is commonly called a Herd. Other collective nouns you may see include Pod and Rookery.

A collective noun is a term used to group or describe a collection of individuals of a specific species. In the case of walruses, these social marine mammals belong to the family Odobenidae and form tightly-knit communities known as herds, haulouts, or pods. While each of these terms can refer to different aspects of their communal behavior, collectively they exemplify the diverse and fascinating social structures of walruses. Firstly, herds refer specifically to the grouping of walrus females and their young offspring. Female walruses typically gather in these herds during the reproductive season to give birth and care for their young. These groups can range in size from a few individuals to several dozen, and they exhibit strong bonds as mothers collaborate to protect and raise their calves. Secondly, haulouts describe gatherings of adult walrus males of various ages. These haulouts are typically formed during the reproductive off-season and are characterized by large males of impressive size and tusks. The purpose of haulouts is for males to establish social hierarchies, engage in mating rituals, and rest between foraging trips. Haulouts can be considerable in number, with individuals often seen piled together in tight spaces, creating a visually striking spectacle. Moreover, the term "pod" can also be used to describe a group of walruses, which includes all members of a particular walrus community. Pods are more encompassing than herds or haulouts, representing the complete social unit of a particular geographical area. These groups can consist of both males and non-breeding females, and each pod has its own dynamic and social structure. Throughout these different collective nouns, walruses exhibit the cooperative nature of their species. By grouping together, they engage in various hierarchical interactions, protective behaviors, and communal activities that strengthen their social bonds. Understanding these collective nouns helps us appreciate the incredible social dynamics of walruses and their crucial role in their marine ecosystems.
