An open circulatory system is made up of a heart, vessels, and hemolymph. This diagram shows how the hemolymph is circulated throughout the body of a grasshopper. The hemolymph is first pumped through the heart, into the aorta, dispersed into the head and throughout the hemocoel, then back through the ostia that are located in the heart, where ...
The largest falcon is the gyrfalcon at up to 65 cm (26 in) in length. The smallest falcon species is the pygmy falcon, which measures just 20 cm (7.9 in). As with hawks and owls, falcons exhibit sexual dimorphism, with the females typically larger than the males, thus allowing a wider range of prey species. [10]
The male (called the "tiercel") and the female (simply called the "falcon") both leave the nest to gather prey to feed the young. [58] The hunting territory of the parents can extend a radius of 19 to 24 km (12 to 15 mi) from the nest site. [96] Chicks fledge 42 to 46 days after hatching, and remain dependent on their parents for up to two ...

Eleonora's falcon (Falco eleonorae) is a medium-sized falcon. It belongs to the hobby group, a rather close-knit number of similar falcons often considered a subgenus Hypotriorchis . The sooty falcon is sometimes considered its closest relative, but while they certainly belong to the same lineage, they do not seem to be close sister species .
The peregrine falcon is the fastest bird, and the fastest member of the animal kingdom, with a diving speed of over 300 km/h (190 mph). [1] The fastest land animal is the cheetah . Among the fastest animals in the sea is the black marlin , with uncertain and conflicting reports of recorded speeds.
