The garganey (Spatula querquedula) is a small dabbling duck.It breeds in much of Europe and across the Palearctic, but is strictly migratory, with the entire population moving to Africa, India (in particular Santragachi), Bangladesh (in the natural reservoirs of Sylhet district) and Australasia during the winter of the Northern hemisphere, [2] where large flocks can occur.
[4] [5] For example, a large marine vertebrate may eat smaller predatory fish but may also eat filter feeders; the stingray eats crustaceans, but the hammerhead eats both crustaceans and stingrays. Animals can also eat each other; the cod eats smaller cod as well as crayfish, and crayfish eat cod larvae. The feeding habits of a juvenile animal ...
[2] [3] Marine microorganisms have been variously estimated to make up about 70%, [4] or about 90%, [5] [6] of the biomass in the ocean. Taken together they form the marine microbiome. Over billions of years this microbiome has evolved many life styles and adaptations and come to participate in the global cycling of almost all chemical elements ...

Consequently, the saturation ...
These birds probe with their bill in mud or shallow water, also picking up food by sight. They mainly eat insects and aquatic animals. Baillon's crakes are very secretive in the breeding season, and are then mostly heard rather than seen. They are then noisy birds, with a rattling call like that of the edible frog, or perhaps garganey. They can ...
Nevertheless, the lumpsuckers do have a C-startle response, which is apparently mediated by other hindbrain cells. [3] Hatchlings have well-developed pectoral fins and adhesive pelvic discs, which the fish use to cling to rocks in shallow water. Young fish remain in shallow, warmer water until fully developed.
