The level of divergence is the highest of any genus of birds, being more typical of the divergence between genera or even families. The northern potoo was for a long time considered to be the same species as the common potoo , but the two species have now been separated on the basis of their calls .
The common potoo, or poor-me-ones (Nyctibius griseus), or urutau is one of seven species of birds within the genus Nyctibius. It is notable for its large, yellow eyes and a wide mouth. Potoos are nocturnal and are related to nightjars and frogmouths. They lack the characteristic bristles around the mouths of true nightjars. [2]
Studies of stomach contents have shown the potto diet consists of about 65% fruit, 21% tree gums and 10% insects. [21] Pottos have also occasionally been known to catch bats and small birds. [ 22 ] Their strong jaws enable it to eat fruits and lumps of dried gum that are too tough for other tree-dwellers.
Birds swallow food and store it in their crop if necessary. Then the food passes into their glandular stomach, also called the proventriculus, which is also sometimes referred to as the true stomach. This is the secretory part of the stomach. Then the food passes into the gizzard (also known as the muscular stomach or ventriculus).
The big-belly seahorse (Hippocampus abdominalis) or pot-bellied seahorse [3] is one of the largest seahorse species in the world, with a length of up to 35 cm (14 in), and is the largest in Australia. [4] Seahorses are members of the family Syngnathidae, and are teleost fishes.

The proventriculus is a standard part of avian anatomy, and is a rod shaped organ, located between the esophagus and the gizzard of most birds. [2] It is generally a glandular part of the stomach that may store and/or commence digestion of food before it progresses to the gizzard. [3]
In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat. It is a part of the digestive tract, essentially an enlarged part of the esophagus. As with most other organisms that have a crop, it is used to temporarily store food. Not all bird species have one.
