The Egyptian plover and the Nile crocodile have a symbiotic relationship in which the plover feeds on parasites on the crocodile's hide. Although a myth exists. The Nile crocodile (Crocodylus niloticus) is an African crocodile, the largest freshwater predator .. Herodotus claimed that Nile crocodiles have a symbiotic relationship with certain birds, such as the Jump up to: "Nile Crocodile Fact Sheet". Well, not the Egyptian Plover bird. Egyptian plovers and crocodiles have a unique symbiotic relationship. Because crocodiles cannot use dental floss, they get.
However, larger skulls may exist, as this study largely focused on crocodilians from Asia. However, the muscles responsible for opening the mouth are exceptionally weak, allowing a person to easily hold them shut, and even larger crocodiles can be brought under control by the use of duct tape to bind the jaws together.
For example, a 3. Only the gharial Gavialis gangeticus and perhaps some of the few very thin-snouted crocodilians is likely to have noticeably diminished bite force compared to other living species due to its exceptionally narrow, fragile snout. More or less, the size of the tendons used to impart bite force increases with body size and the larger the crocodilian gets, the stronger its bite is likely to be.

Therefore, a male saltwater crocodile, which had attained a length around 4. The largest accurately measured male, shot near Mwanza, Tanzania, measured 6.
Among crocodilians today, only the saltwater crocodile occurs over a broader geographic area,  although other species, especially the spectacled caiman Caiman crocodilus due to its small size and extreme adaptability in habitat and flexibility in dietseem to actually be more abundant. The Nile crocodile has historically been recorded in areas where they are now regionally extinct.
For example, Herodotus recorded the species inhabiting Lake Moeris in Egypt. Additionally, the Nile crocodile is known from fossil remains to have once inhabited Lake Edward on the border between the Democratic Republic of the Congo and Uganda. They are thought to have become extinct in the Seychelles in the early 19th century — They have been spotted in Zanzibar and the Comoros in modern times, but occur very rarely. West African crocodiles are found throughout much of West and Central Africa, ranging east to South Sudan and Uganda where the species may come into contact with the Nile crocodile.
Nile crocodiles are absent from most of West and Central Africa, but range into the latter region in eastern and southern Democratic Republic of Congo, and along the Central African coastal Atlantic region as far north to Cameroon.
In Madagascar, the remnant population of Nile crocodiles has adapted to living within caves. Lucia Bay in This source remains unclear, as their genetics do not match samples collected from captives at various zoos and theme parks in Florida.

When compared to Nile crocodiles from their native Africa, the Florida wild specimens are most closely related to South African Nile crocodiles. More than half of the crocodiles observed by Cottif not disturbed, spent the hours from 9: If their jaws are bound together in the extreme midday heat, Nile crocodiles may easily die from overheating.
In South Africa, Nile crocodiles are more easily observed in winter because of the extensive amount of time they spend basking at this time of year. More time is spent in water in overcast, rainy, or misty days. Crocodiles in aestivation are totally lethargic, entering a state similar to animals that hibernate.
Only the largest individuals engaging in aestivation leave the burrow to sun on warmest days, otherwise these crocodiles rarely left their burrows. Aestivation has been recorded from May to August.
Nile crocodiles normally crawl along on their bellies, but they can also "high walk" with their trunks raised above the ground. Although this clearly is a deliberate behaviour for the species, the purpose is not definitively known.
Gastroliths are not present in hatchlings, but increase quickly in presence within most crocodiles examined at 2—3. One crocodile measuring 3. Cott felt that gastroliths were most likely serving as ballast to provide stability and additional weight to sink in water, this bearing great probability over the theories that they assist in digestion and staving off hunger.
In the water, this species is an agile and rapid hunter relying on both movement and pressure sensors to catch any prey unfortunate enough to present itself inside or near the waterfront. However, for such large animals, their stomachs are relatively small, not much larger than a basketball in an average-sized adult, so as a rule, they are anything but voracious eaters.
In general, at the smallest sizes 0. It is while swallowing that the bits of flesh get stuck in their teeth. You will find them swimming just like this beneath the surface of water with their eyes and nostrils just above.
Often you will find them lazing around in the sun with their mouth wide open. They have powerful jaw muscles and can keep their mouth open for a long time.
Crocodile and the Plover Bird
Let us look at the Plover Bird closely. She lives in pairs or in small groups near water bodies, just like our crocodile does. She flies in groups. When a pair lands after the flight, they greet each other by raising their wings in a way that shows the black and white marks on them. They greet each other regularly! They get into its mouth boldly, eat the food and fly away.
Even when a Plover Bird is not around, his teeth still need to be cleaned! And a crocodile needs all this cleaning in spite of the following fact: A crocodile can grow new teeth through out his life. Each time an old tooth falls out a new one will grow up to replace it!
Crocodiles on the river Nile are the ones that benefit from their service. Nile crocodiles are the second largest in the world and are so ferocious that they can walk to areas much far from their water home to catch cattle prey.
