What is a group of Whales called?

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

A collective noun is a term that refers to a group of individuals from the same species. In the case of whales, these magnificent creatures, renowned for their vast size and extraordinary marine presence, too have some collective nouns frequently used to depict them in a particular setting. When a group of whales congregate or travel together within the vast expanses of the ocean, they can be referred to as a pod. The term "pod" is the most commonly used collective noun for whales and often encompasses varying species, including dolphins. Each pod consists of several individuals swimming in a synchronized manner, tightly connected by a social bond and occasionally exhibiting cooperative behaviors while hunting or caring for their young. Pods can range in size, with some consisting of just a few individuals while others may comprise dozens of members. For certain whale species that migrate over long distances for different purposes, such as feeding or reproduction, a collective noun often used is a herd. This term emphasizes the amassed grouping of whales, often moving with a specific purpose in mind. Herds can consist of various individuals from the same species, traveling together primarily to feed on the abundance of prey that resides in specific regions or to establish mating grounds. Apart from the pod and herd, some species of whales have acquired unique collective nouns based on their specific behaviors, such as bowheads, which are known to form a float of whales. A float typically describes a group of these massive, benthic-feeding whales slowly drifting together in feeding aggregations, sometimes surrounded by walls of broken ice as they navigate through the Arctic regions seeking sustenance. In summary, the most frequently used collective noun for whales is a pod. These awe-inspiring creatures display an array of social behaviors and form tight-knit groups for various purposes, indicating their remarkable ability to communicate and cooperate within their species. Additionally, specific species of whales may also exhibit different collective nouns based on their distinct behaviors or ecological requirements.
