Fauna of Pakistan up from the Arabian Sea to spawn in freshwater. Species that are important to people as food, such as the golden mahseer and large freshwater shrimp ("Macrobrachium" species), are part of the abundant aquatic life. Along the shores of Astola and Ormara beaches of Balochistan and Hawk'e Bay and Sandspit beaches of Sindh are nesting sites for five endangered species of sea turtles: green sea, loggerhead, hawksbill, olive ridley and leatherback. Sea snakes such as yellow-bellied sea snake are also found in the pelagic zone of the sea. The wetlands of Pakistan are also a home to the endangered species
Loggerhead shrike be energetically stressed and underweight. Insects are consumed in mid-flight, but vertebrates usually require more handling time and therefore more energy. Due to the shrike's small size in proportion to the size of its prey, it must rely on specialized adaptations to facilitate its hunting. The powerful, hooked beak of the loggerhead shrike allows it to sever the neck of a small vertebrate. Larger prey are subjected to impaling, in which they are pushed down into a sharp projection, such as a thorn or barbed wire. The bird can then tear off flesh by using the projection as an anchor.
