Crocodiles and Alligators are often confused with because of the physical similarities. When an average person encounters a crocodile or alligator, it is most probable that they guess which animal it is and get it wrong. However, the only thing in common is the body structure. Not all of the similarities have to do with the similar physical shape of the crocodiles and alligator’s. In fact, the similarities go beyond. On the other hand, the differences deal with the most detailed dissimilarities between the crocodiles and alligators body.
One of many similarities crocodiles and alligators have is that these animals are reptiles. Crocodiles and alligators belong to the same subfamily so it is likely for them to have the same physical shape.

For example, there is a big difference when it comes to a crocodiles and alligators snout. Alligators have a U-shaped snout with a wider head and sharp teeth that hide when the mouth is closed. In contrast to alligators, a crocodile have a V-shaped snout with a thinner head and have a “toothy grin” when the mouth is closed. Additionally the alligators upper jaw is more located more forwards than the crocodiles, this also affects the how the teeth are structured. Although both of these animals’ teeth are strong, the crocodiles have a more defined strength because it can destroy a turtles shell faster than an alligator. Furthermore, crocodiles have lingual glands that make salt water tolerable. Another major difference is the capacity of length between the two reptiles. Crocodiles tend to grow 5. 8 meters compared to an 4.3 alligator. Moreover, female crocodiles lay their eggs in mud or sand whereas the female alligators lay eggs on mounds near water. Another difference between alligators and crocodiles are the amount of time it takes to take care of the newborns. Alligators usually stay a few months or 1 year until the babies are strong enough to fend for themselves unlike crocodiles that stay with the babies 2
Finally, we will get to know some interesting facts about american alligators. The american alligator have three thousand teeth in a lifetime. They use nature to hunt, they use branches to balance them on there head to trick the birds so they will think it is a tree and they will make a nest. There is two million american alligators just between Louisiana and Florida. American alligators can survive is extreme weather. In conclusion these are some interesting facts on american alligators.
One of the main ways that you can tell an alligator and a crocodile apart is the nose or the snout. On an alligator the nose of the animal is more of a u shape. Another way is the crocodile teeth stick out of its mouth when its mouth is closed. They both have really sharp teeth and a lot of power in their bite. The average length of a crocodile is a whopping 19 feet long. Compared to the alligator is huge. Alligators are
Reptiles are crucial in the food chain. Not only are their predators but are also prays to others making them very important to the ecosystems. They control pest and acts as pollinators.
Another similarity is the way that the gods spoke to people. Both the Egyptian creator gods and the Israelite Creator God spoke through prophets or priests. God spoke through prophets, such as Moses, to the Israelites. The Egyptian gods spoke through oracles, priests and pharaohs to talk to the Egyptians. Some of the pharaohs even thought that they were reincarnations of the god Horus. Both the Egyptians and the Israelites had a creator god who spoke to them through prophets and priests.
Alligators are large, lizard like, scaly creatures that closely resemble crocodiles. These beasts are native to only the United States and China, where it is now nearly extinct. Male Gators can grow up to 4 and a half meters long, the females up to 3 and half. However, Chinese alligators are much smaller, growing to be about half the size of a female American one. Gators vary in color, from yellow to green to nearly black in old age. An alligators tail is extremely muscular, used mostly in the water to propel the gator forward like a rocket.
According to the Smithsonian Zoological Park one of the features that makes American Alligators unique is “The large fourth tooth in the lower jaw of an alligator which fits into a socket in the upper jaw and is not visible when the mouth is closed.” As the teeth of the American Alligator wear down they get replaced which can lead to replacing their teeth over 2,000 times in their lives. The American Alligator has nostrils that stick up further than the rest of the snout, this is so they can breathe while the rest of their body is under water. The eyes of the American Alligator consist of upper and lower eyelids that protect them. They have a third eyelid, which protects its eyes when they swim underwater. Alligator eyes have also developed to see in the dark by reflecting light back into its own eyes.
The alligator is one of the largest living reptiles today. In North America, they inhabit freshwater swamps or wetlands in the south, from Texas to North Carolina. Distinguishing features include the fourth mandibular tooth, the long, broad snout, and the thick, scaly skin. Like some other reptiles, alligators have temperature-dependent sex determination, which is a non-genetic way of determining the sex ratio of offspring produced. Unlike other reptiles, alligators exhibit parental care; they nest-guard, and even offer evidence of maternal care for juveniles after hatching. Through the reviewing of multiple experiments conducted on Alligator mississippiensis, evidence is provided for the temperature-dependent mode of sexing and maternal
One misty morning in 2003, deep under the cover of the largest subtropical wilderness in the United States, a group of tourists set out for a day of exploration in the Everglades. They hoped to see some of the diverse and unique species that the Everglades are famous for, and maybe snap a few cool pictures to show their friends. They could never have anticipated what they would actually discover. A short way into their trek, the party was drawn to a noisy struggle nearby. They followed their ears to a duel between an alligator and a huge Burmese Python. The alligator clamped his jaws around the snake. The snake wrapped its body around the alligator. The tourists
Alligators are not that uncommon, and yet the local flamingos are white or so pale pink that if
Birds are closely related to crocodiles because they share the same ancestry with the dinosaurs. To compare the crocodile and lizard, one would think the lizard is closely related to crocodiles, as we read in our text, "similar structures don't always reveal common ancestry." Crocodiles and birds evolved having the same common ancestry as the dinosaur. Lizards, on the other hand, do not share a close common ancestor with crocodiles or dinosaurs, their common ancestry is more distant.
be able to be found here. Listen for the sinister rattling sounds of timber rattlesnakes when walking to avoid angering one and getting bit. Alligators can be seen swimming through the marshy swamp lands. Gators are seen sitting on strips of muddy land in the middle of the water guarding eggs from predators. Animals the alligators have to
These two features earlier are examples that we can see with our naked eyes, but the DNA make up that we cannot see with our eyes alone are also laid out the same as well. In the evolutionary pathway, the genes that turn on and off for humans and fish are related through the instructions on how they function. All living things with limbs have in common the Sonic hedgehog gene (Shubin, p. 53). The Sonic hedgehog gene can control the development of the limbs in these creatures. To determine if the development of vertebrate animals can be interpreted in the same way, or have the same effect, the injection of vitamin A was used to inject into a shark, mice, and chicken embryos to see if the results were the same. The results turned out that the injection of vitamin A has indeed changed the development of limbs in these embryos. The effects cause the shark to have a mirror image of its fin, and the mice and chicken have duplication of bones in the limbs (Shubin, p.56-57). It becomes clear of what will happen if
RATIONALE: The purpose of the lesson is to have students observe and describe how young animals resemble their parents. This lesson will give students the foundation knowledge they need to understand the similarities in physical appearance of young animals and their parents. It will also allow for them to understand differences in different species, through the physical appearances.. The knowledge can be applied to genetics and how young animals are similar and different to their parents in future grades.
Is the story a myth? The crocodile had "gold shiny smooth skin". To be a myth it has to have a pattern. The story has a pattern in it then its a myth. The color of the crocodile and how it changed when he was in the sun and it turned to "ugly green lumpy armor" to be a myth it has to have a why. The story has a why which means its a myth. Yes, the story is a myth because it has a pattern, a why, and a belief
First, Crichton noted that duckbilled dinosaurs were herbivores which are supported by a trace fossil found in the coal beds of the western North America that indicated footprints with plant fossils (Martin 2006). Furthermore, duckbilled dinosaurs lived in a vegetated environment that they had to consume enough food relative to their body size. Duckbilled dinosaurs had lengthened their skull and smoothed snout to obtain and process more food. The Dilophosaurus was described as two curved crests that extended from the eyes to the nose. The crest created a V shape on the head with red and black stripes on the crests (Crichton, 1990). Based on fossil evidence, the Dilophosaurus had two crests on the head, but there was no indication of the pigment of the crest. Next, the book stated that the T. rex does not bite the prey, instead, it twisted and tore the
