Where native large crocodilians and humans live close to each other, crocodile attacks on humans occasionally occur. In fact, only 6 out of 22 crocodilian species are considered dangerous to adult humans.Notes 1 And in those six species, only individuals 2 meters (6.6 feet) and longer in length are capable of killing adult humans. Two species, which are also the largest and most aggressive, saltwater crocodile and Nile crocodile have a well-known reputation for preying on humans. These two also have the most documented cases. Each year, hundreds of people die of either Nile or saltwater crocodile attacks. The mugger crocodile, which can be found throughout the Indian subcontinent and the surrounding countries, also very dangerous to humans, killing many people in India every year. Despite the American crocodile is considered to be less aggressive, a few (unverified) fatally attacks reported. Also, species/individuals smaller than 2 meters can inflict painful and dangerous bites on adult humans and they even capable of killing children. Even then, according to the Worldwide Crocodilian Attack Database most interactions between crocodiles and humans are non-eventful.

Birds (Aves) range in size and weight from the 5 cm (2 in) and 1.6-2 grams bee hummingbird to the 2.75 m (9 ft) and 104-156 kg (229-344 lbs) ostrich. Here are the top 15 largest birds in the world (by body weight).
Birds form one of six basic animal groups, with the others being amphibians, fish, invertebrates, mammals and reptiles. They are endothermic vertebrates, characterized by feathers, toothless beaked jaws, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. They reproduce by laying of hard-shelled eggs (eggs fertilize inside the female). The fossil record indicates that birds are the last surviving group of dinosaurs.

Identifying the largest dinosaurs ever lived isn’t an easy task, because it’s very rare to unearth a complete fossil. Furthermore, only a tiny percentage of these amazing animals ever fossilized, and most of these “lucky” bodies will remain buried underground forever. So, we may never know exactly what dinosaur was the biggest (or the tiniest) ever.
Despite this fact, size always has been one of the most interesting aspects of these prehistoric animals. There are extreme variations in their size, from the tiny hummingbirds, which can weigh as little as three grams, to the titanosaurs, which could weigh as much as 70 tonnes, or even more.
