The word Pinniped means 'feather foot' or 'fin-footed' in Latin. Generally known as seals, they are shaped like torpedoes and have four webbed flippers for their spindle-shaped bodies as they have wide torsos and narrow hindquarters. These animals have adapted to be like amphibians and thus, have sensory organs that function well in both water and air. They have large eyes and well-developed and functioning whiskers which help them feed in dimly lit waters. Their tail is small which limits dragging. All the species of seals have short fur except walrus which have none. They are known to be visual predators as they have extremely short ears like fur seals and sea lion or sometimes lack external ear flaps like true seals but they have great hearing, especially underwater. They usually live in rich marine environments. Male Pinnipeds are generally larger than females and, in some species, both males and females are similar in size. The Pinnipeds comprise around 33 species enjoying a population of up to or more than 100,000 but there are certain species that are rare to find or considered as vulnerable. Those species include- Saimaa ringed seals, Lacs de Loups Marine harbor seals, Mediterranean monk seals, Hawaiian monk seals, and honestly, it is quite fascinating to learn about Pinnipeds.
