The gharial (Gavialis gangeticus), also known as gavial or fish-eating crocodile, is a crocodilian in the family Gavialidae and among the longest of all living crocodilians. . Mature females are 2.6 to 4.5 m (8 ft 6 in to 14 ft 9 in) long, and males 3 to 6 m (9 ft 10 in to 19 ft 8
In comparison, piscivorous water birds from Africa eat far more per day despite being a fraction of the body size of a crocodile; for example, a cormorant eats up to 1.4 kg (3.1 lb) per day (about 70% of its own body weight), while a pelican consumes up to 3.1 kg (6.8 lb) per day (about 35% of its own weight).
A crocodile needs from a tenth to a fifth of the food necessary for a lion of the same weight and can live half a year without eating. [80] Lower food requirements and adaptive metabolisms allow reptiles to dominate the animal life in regions where net calorie availability is too low to sustain large-bodied mammals and birds.
While birds, including raptors, wading birds and roadrunners, and mammals are known to prey on reptiles, the major predator is other reptiles. Some reptiles eat reptile eggs, for example the diet of the Nile monitor includes crocodile eggs, and small reptiles are preyed upon by larger ones.
[106] [113] The diet of eagle-owls in Norway was dominated in coastal areas by water birds, overall for the nation 53% of the food was made of birds, the species most commonly identified as caught being the 388 g (13.7 oz) common gull (Larus canus), 430 g (15 oz) common puffin (Fratercula arctica) and 2,070 g (4.56 lb) common eider (Somateria ...

Other water birds recorded as prey include cormorants (up to 8.6% of the recorded prey in Santa Rosa and Santa Cruz Islands), auks, grebes and loons. [10] [30] Other raptorial birds can sometimes become semi-regular prey, such as various hawks which are recorded largely in North America at locations such as Oregon (8.8% of prey remains) and ...
