Salmon Hat
A salmon hat is a cultural fad displayed by orcas, where they wear dead salmon upon their heads. It was first observed in 1987 with southern resident orcas and was a relatively short-lived phenomenon. In 2024, the behaviour was observed again with orcas in Puget Sound. The motivations for salmon hats are unclear, but other orcas will mimic the behaviour once it begins. One hypothesis is that orcas wear salmon hats to display high food availability, or that the same individuals that originally started the trend revitalized it. It may also indicate playfulness.

Orcas
The orca (''Orcinus orca''), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. The only extant species in the genus '' Orcinus'', it is recognizable by its black-and-white-patterned body. A cosmopolitan species, it inhabits a wide range of marine environments, from Arctic to Antarctic regions to tropical seas. Orcas are apex predators with a diverse diet. Individual populations often specialize in particular types of prey, including fish, sharks, rays, and marine mammals such as seals, dolphins, and whales. They are highly social, with some populations forming stable matrilineal family groups (pods). Their sophisticated hunting techniques and vocal behaviors, often unique to specific groups and passed down from generation to generation, are considered to be manifestations of animal culture. The International Union for Conservation of Nature (IUCN) lists the orca's conservation status as data deficient as multiple orca types may ...

Salmon
Salmon (; : salmon) are any of several list of commercially important fish species, commercially important species of euryhaline ray-finned fish from the genera ''Salmo'' and ''Oncorhynchus'' of the family (biology), family Salmonidae, native to tributary, tributaries of the North Atlantic (''Salmo'') and North Pacific (''Oncorhynchus'') basins. ''Salmon'' is a colloquial or common name used for fish in this group, but is not a scientific name. Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen, all coldwater fish of the subarctic and cooler temperate regions with some sporadic endorheic populations in Central Asia. Salmon are typically fish migration, anadromous: they hatch in the shallow gravel stream bed, beds of freshwater headstreams and spend their juvenile fish, juvenile years in rivers, lakes and freshwater wetlands, migrate to the ocean as adults and live like sea ...

Southern Resident Orca
The southern resident orcas, also known as the southern resident killer whales (SRKW), are the smallest of four communities of the exclusively fish-eating ecotype of orca in the northeast Pacific Ocean. The southern resident orcas form a closed society with no emigration or dispersal of individuals, and no gene flow with other orca populations. The fish-eating ecotype was historically given the name 'resident,' but other ecotypes named 'transient' and 'offshore' are also resident in the same area. The U.S. National Marine Fisheries Service listed this distinct population segment of orcas as endangered, effective from 2005, under the Endangered Species Act. In Canada the SRKW are listed as endangered on Species at Risk Act Schedule 1. They are commonly referred to as "fish-eating orcas", "southern residents", or the "SRKW population". Unlike some other resident communities, the SRKW is only one clan (J) that consists of 3 pods (J, K, L) with several matrilines within each pod. As ...

Puget Sound
Puget Sound ( ; ) is a complex estuary, estuarine system of interconnected Marine habitat, marine waterways and basins located on the northwest coast of the U.S. state of Washington (state), Washington. As a part of the Salish Sea, the sound (geography), sound has one major and two minor connections to the Strait of Juan de Fuca, which in turn connects to the open Pacific Ocean. The major connection is Admiralty Inlet; the minor connections are Deception Pass and the Swinomish Channel. Puget Sound extends approximately from Deception Pass in the north to Olympia, Washington, Olympia in the south. Its average depth is and its maximum depth, off Jefferson Point between Indianola, Washington, Indianola and Kingston, Washington, Kingston, is . The depth of the main basin, between the southern tip of Whidbey Island and Tacoma, Washington, Tacoma, is approximately . In 2009, the term Salish Sea was established by the United States Board on Geographic Names as the collective wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iberian Orca Attacks
Beginning in 2020, a subpopulation of orcas (''Orcinus orca'') began ramming boats and attacking their rudders in waters off the Iberian Peninsula. The behaviour has generally been directed towards slow-moving, medium-sized sailboats in the Strait of Gibraltar and off the Portuguese, Moroccan and Galician coasts. The novel behaviour is thought to have spread between different pods, with over 500 reported interactions from 2020 to 2023 attributed to fifteen different individual orcas (the exact number is still debated between certain scientists). Background The Iberian orca subpopulation lives in the coastal waters of the Iberian Peninsula and is genetically distinct from other orca populations in the Northeast Atlantic. The orcas follow the seasonal migration of Atlantic bluefin tuna (''Thunnus thynnus''), their primary food source, gathering in the early spring in the Strait of Gibraltar. Through the summer, they remain in the Strait before travelling north along the coast of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal Behavior
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...
