Crocodile bulks of swallowed prey flesh and bone. Many large crocodilians swallow stones (called gastroliths or stomach stones), which may act as ballast to balance their bodies or assist in crushing food, similar to grit ingested by birds.

Since they feed by grabbing and holding onto their prey, they have evolved
Kittlitz's plover suburbs and ports. In Ghana, wetlands are threatened by coastal erosion and developments that include drainage and wetland reclamation The fraction of the population migrating via the east Atlantic is vulnerable to avian malaria and would be greatly threatened in case of an outbreak of this disease. The same applies to avian botulism, which the Kittlitz’s plover is susceptible to. Kittlitz's plover Kittlitz’s plover ("Charadrius pecuarius") is a small shorebird (35-40 g) in the family Charadriidae that breeds near coastal and inland saltmarshes, sandy or muddy riverbanks or alkaline grasslands with short vegetation. It is native to much of Sub-Saharan
