An overhead view of louise's septum, which may have caused the animal to experience nosebleeds, may have caused high shearing stresses along the nasal walls.

A research published in the journal Anatomical Record shows that humans and crocodiles have the same deviated septum.
The crocodylians are some of the most rare animals on the planet, and members of a group that once lived with the dinosaurs. gharials are native to India and have long and thin snouts that allow them to cut through water when hunting prey. This snout is used by males to house a longer nose that ends in an enlarged bulb.
These animals seem to have little in common with humans. A new study led by the assistant professor of basic sciences at the College of Osteopathic Medicine at Arkansas State University shows thatgharials suffer from nasal septal deviation.
Up to 80% of people have a deviated septum, a condition in which the nose is off-center, according to the Cleveland Clinic. The condition is mild in most individuals, but larger deviations can restrict breathing and require surgery.
Bourke and his colleagues are the first to document deviated nose in crocodylians. They analyzed the heads of several gharials, including that of a large female from the Fort Worth Zoo nicknamed "Louise," which fueled their curiosity.
The specimen was scanned for a separate project on gharial anatomy, but it was found to be a weird nose. I saw the roller coaster and wondered what it meant for respiration.
Louise's extreme anatomy was shared by Holliday with a paleontologist who specializes in modeling fluid dynamics in animal noses using sophisticated computer software.
The degree of nasal septal deviation witnessed in the animal is shown in the graphic. The credit is given to the person, who is a doctor, by the person, who is a doctor, by the person, who is a doctor, by the person, who is a doctor, by the person, who is a doctor, by the person, who is a doctor.
We don't know much about normal gharial anatomy. "I couldn't pass up such a unique opportunity, I have studied dinosaurs in the past, and I couldn't think of a better place to start," said Bourke.
The team began collecting samples from other gharials housed in zoos around the country. Louise had the most extreme septal deviation.
Louise had to work harder to achieve the same breathing rate as her peers because of her severe nose septum deviation. The animal may have been more prone to nosebleeds because of the high shearing stresses along the nasal walls. Louise lived to the ripe old age of 50 despite the challenges she faced due to her nasal pathology.
"It's a testament to the resilience of crocodiles," said Bourke. A human with this pathology would need surgery to fix it.
The researchers found that gharial septal deviation is different from humans. Nicole Fontenot, a fourth-year NYITCOM student and study co-author, said that when the septum deviates in humans, a part or all of the septum bows into one of the airways. The gharials have a long septum that wiggles back and forth along the snout, creating a wavy pattern.
The stretched-out noses of many other animals, including crested, duck-billed dinosaurs and crocodiles, are not found in modern crocodylians. Some of them would have suffered from septum deviations. Other crocodylians don't seem to be as prone to deviated noses.
Other crocodylians have larger snouts. The space inside the nose is premium if you thin out the snout. The long and thin septa of Gharials doesn't need much to make them start wobbling.
The researchers will examine the sound-production abilities of gharials' unique noses.
The Anatomical Record has more information on the Septal deviation in the nose of the longest faced crocodylian. There is a book titled "10.1002/ar. 24831."
The research found a problem with the nose of long-nosed crocodile relatives.
