Pronunciation: [wˈɒlɹəsɪz] (IPA) 
The spelling of the word "walruses" might seem confusing, but it follows a simple rule in English. The plural form of the noun "walrus" is spelled with an "-es" ending because it ends in a voiced "s" sound. This sound is created by the final "s" and although not pronounced separately, it makes the "-es" necessary for correct spelling. So, "walruses" is pronounced as "wɔːlrəsɪz" in IPA transcription.
Walruses are large marine mammals belonging to the order Pinnipedia and family Odobenidae. They are characterized by their distinct appearance, with a rotund body, flipper-like limbs, and prominent tusks. These tusk-like canines, which are present in both males and females, can reach lengths of up to three feet and are actually elongated canine teeth. Walruses are known for their social nature, and they typically form large groups called herds or pods.
These magnificent creatures inhabit the Arctic regions, including the Arctic Ocean and surrounding seas. They are specially adapted to survive in this harsh environment, featuring a thick layer of blubber that helps them withstand cold temperatures and provides buoyancy. Walruses are superb swimmers, displaying agility and speed in the water despite their impressive size, which can exceed 10 feet in length and weigh up to 3,700 pounds.
Walruses primarily feed on benthic invertebrates like clams, mussels, and snails, which they locate using their sensitive vibrissae (whiskers), covering both the upper lip and snout. They use suction to draw their prey out of the sediments, while their powerful teeth help them crush the shells.
These magnificent creatures have faced population decline, largely due to climate change impacting their sea ice habitat and environmental factors affecting their food availability. Consequently, they are classified as vulnerable by the International Union for Conservation of Nature (IUCN). Efforts are being made to protect their habitats and regulate hunting activities to ensure the survival and conservation of these remarkable marine mammals.
The word "walrus" is derived from the Old Norse word "hrossvalr", which means "horse-whale". This term was likely a translation of the Old English word "hringhvalur", which also meant "ringed or curved whale". Over time, the word "hrossvalr" evolved into "walrus" in English. The use of the plural form "walruses" follows the general rule of adding "-es" to form the plural of nouns ending in "-us" in English.
