It’s less than 1 percent of their body weight. A 3.5 metres croc has a brain the size of a walnut. They can learn to use tools and are very intelligent. They are also very territorial and will attack other crocs if they get too close. They will also defend their territory with their teeth and claws. Crocs can live for up to 30 years.

Do crocodiles have small brains?
They crocodiles have small brains. crocs are not simple-minded, but they do. Communication, cooperation and parental care are some of the social behaviour that they display. Crocs have been around for a very long time. The earliest known crocodile fossils date back to the Early Cretaceous period, about 145 million years ago.
Crocodyliformes are a group of crocodilian-like reptiles that include alligators (alligators), caimans (gators) and caiman (mammals). They are found in tropical and subtropical regions of the world. The largest of these species is the African gator (Alligator mississippiensis), which can grow to a height of 3.2 metres and weigh as much as 1,000 kilograms (2,500 pounds).
Do crocodiles have intelligence?
Recent studies have found that crocodiles and their relatives are highly intelligent animals capable of sophisticated behavior such as advanced parental care, complex communication and use of tools for hunting. New research shows how sophisticated their hunting techniques can be.
A team of researchers from the University of California, Santa Cruz, and the National Institute of Standards and Technology (NIST) in Gaithersburg, Md., has discovered that a crocodile’s ability to use tools is not limited to hunting, but can also be used to communicate with other members of its species.
The findings, published in the journal Proceedings of the Royal Society B: Biological Sciences, could have implications for the evolution of complex social behavior in other animals, including humans. “Crocodiles are among the most intelligent and social animals on the planet,” said study co-author and NIST postdoctoral research associate, Dr. Michael J. O’Brien. “Our findings suggest that they may have evolved sophisticated social behaviors to help them survive and thrive in a hostile environment.”
The researchers studied the behavior of two species of crocodyliforms, a group of crocodilians that includes alligators, caimans and caiman.
Do crocodiles have memory?
Crocodiles are the smartest of all reptiles. They have a very good memory and can plan ahead. They have special eyes that allow them to see in the dark. Crocodiles can live up to 30 years. The largest crocodile is the Crocodylus acutorostratus, which can reach a length of more than 20 feet. The largest living crocodiles live in Africa and Asia.
How intelligent are alligators?
According to a recent study, their intelligence might be better. American alligators and Indian marsh crocodiles have begun balancing twigs on their snouts to lure wading birds, which try to grab them with their beaks. The study was published in the Journal of Experimental Biology.
How do alligators poop?
Both feces and nitrogenous waste are excreted through a single opening – the cloaca. The consistency of the scat makes it hard to differentiate it from other animals. Alligators have a long, thin tongue, which they use to slurp food from the water. They also use their tongue to pick up insects and other small objects.
Can crocodiles roar?
In addition, members of both sexes may produce a loud roar during the breeding season. The head and tail rise high in the air as a roaring crocodile tenses the muscles of its body. The roar is so loud that it can be heard from miles away.
Crocodiles are also known for their ability to climb trees. They can reach heights of up to 30 feet (9 meters) and are capable of reaching speeds of 40 miles (64 kilometers) per hour (25 mph).
How big is a dolphin brain?
Bottlenose dolphins have bigger brains than humans (1600 grams versus 1300 grams), and they have a brain-to-body-weight ratio greater than great apes do (but lower than humans). Marino that they are the second most encephalized beings on the planet. Size is not the only thing that distinguishes dolphins from other mammals. “Dolphins have the largest brains in the animal kingdom,” he , “but they also have some of the smallest brains of any vertebrate.”
Marino and his colleagues have been studying dolphins for more than a decade, and their findings are consistent with the idea that dolphins are smarter than we give them credit for. In a study published last year, for example, the researchers found that when dolphins were given a choice between two objects, they chose the one that had the highest number of objects in it, even when the objects were the same size.
They also showed that the dolphins’ brains were larger than those of other animals, suggesting that they are capable of higher-level thinking. And in another study, published in 2012, Marino’s team found evidence that dolphin brains are more similar to humans’ than to any other animal’s.
