Top 10 Animals with a Throat Pouch (Gular Pouch)

Frigate Bird

The world around us is full of elements very beautiful and unique that makes them attractive. Nature has bestowed animals and birds with unique survival features, some of them weird enough to attract attention. Wings, large beaks, patterned skins, long tails, and strong bones are some of the features animals possess to help them survive in the animal kingdom. Some animals, mostly birds possess one such remarkable feature known as the Gular Pouch or a throat pouch.

 Birds have a gular pouch in the form of an area of featherless skin that joins their lower beak to the neck. The skin forms a flap, or a gular pouch, which is used to store fish and other prey while hunting. Other animals may have a similar throat pouch in the form of a gular sac, throat sac, or vocal sac. Below we examine the top 10 animals with a gular pouch. The beauty of their gular structure will leave you awe-struck. Check them out.

Animals with a Throat Gular Pouch

1. Frigate Bird

Frigate birds belong to the family of seabirds which are found across all tropical and subtropical oceans. They are distinguished by their black plumage, long, deeply forked tails and long hooked bills. Their long narrow wings can reach a wingspan of about 2.3 m. The male birds have a bare red skin patch on their throat which is the gular sac. This is hardly visible outside the breeding season. Come the breeding season, and the male birds display their inflated bright red gular sacs for courting, which gets inflated to the size of a person’s head.

The Southern Flying lizard or the Indian flying lizard is a species of lizard found in the Western Ghats and hilly forests of Southern India. They are found on trees in forests and palm plantations.

They can glide by extending their patagia, flaps of skin on the side of the body as wings.
