Nile crocodile stability and additional weight to sink in water, this bearing great probability over the theories that they assist in digestion and staving off hunger. However, Alderton (1998) stated that a study using radiology found that gastroliths were seen to internally aid the grinding of food during digestion for a small Nile crocodile. Herodotus claimed that Nile crocodiles have a symbiotic relationship with certain birds, such as the Egyptian plover ("Pluvianus aegyptius"), which enter the crocodile's mouth and pick leeches feeding on the crocodile's blood, but no evidence of this interaction actually occurring in any crocodile species has been found, and
Madagascan plover environmental change, and thus very sensitive to habitat threats. Three nesting localities are located in protected national parks: lake Tsimanampetsota, Kirindy Mitea, and Baly Bay. Control of predators has been suggested as a conservation measure, however this may be difficult as the predators themselves may be endemic to Madagascar, endangered, or protected species. Madagascan plover The Madagascan plover ("Charadrius thoracicus"), also known as the black-banded plover, is a small (37 g) monogamous shorebird in the family Charadriidae. It is native to western Madagascar that inhabits the shores of lagoons, coastal grasslands, and breeds in salt marshes. These plovers mainly nest
