This year marks the golden anniversary of Steven Spielberg’s groundbreaking summer hit, Jaws, which not only revolutionized our perspective on cinema but also our understanding of sharks. Don’t miss out on the special edition commemorating this milestone!
The portrayal of great white sharks in the movie isn’t particularly sympathetic; Quint compares their eyes to doll’s eyes, suggesting they are lifeless except during an attack. Additionally, Spielberg intentionally left much to the viewer’s imagination as a way to accommodate the technical constraints of the time and because people have an innate ability to be more terrifying than any filmmaker could ever manage.
In this scene, arguably the most captivating part of the movie unfolds within the enclosed space of the boat. Quint proudly displays his collection of wounds, including a chipped tooth and a bump on the head. Hooper then counters with an account of a moray eel bite. The two men engage in a friendly competition, sharing tales about their damaged limbs and scars they’ve earned. They share drinks and laughter, creating a unique moment of camaraderie… but it doesn’t last long. Before you know it, Quint shares the grim story of the USS Indianapolis, recounting a harrowing tale of hunters and the hunted in the vast ocean.
The scars they bear serve as a narrative of their life experiences, encompassing triumphs and hardships, and this principle applies equally to the lives of sharks themselves. A recent study published in the journal Frontiers in Marine Science suggests a revised classification system for scarks (scars on great whites) and other injuries they sustain. This new system aims to aid researchers in deciphering the activities of these elusive predators when we’re not observing them directly.
How scientists are learning about sharks from their scars
Despite white sharks being extensively researched globally, many aspects about them remain a mystery. We’re yet to pinpoint their mating locations and methods, the duration of pregnancy for their offspring, or where they give birth. Their interactions with prey and other predators are mostly guessed due to lack of concrete data. Investigating marine life is challenging because oceans are vast, providing numerous hiding spots. Researchers employ various tools such as underwater microphones and satellite tags to catch a glimpse into the deep sea.
Creating a catalog of shark injuries from the Central California coast could serve as an extra resource for researchers. By analyzing photographs of sharks in this region, they aim to construct a database of images. Their focus isn’t only on identifying the kinds of scars and wounds that sharks sustain, but also when these occurrences take place. This information can be deduced by examining how well healed the injuries are at the time of observation. However, before they can develop a practical tool, they must first decipher the meanings behind these common markings.

Boat propeller injuries typically exhibit neat rows of parallel cuts across the body, whereas squid attacks result in circular scars that gradually narrow, indicative of the size of their tentacles. These circular marks are caused by the tiny teeth surrounding each sucker on a giant squid’s arms, but not all such scars originate from these creatures. Sharkskin can also bear small, circular punctures made by the cookiecutter shark, a unique predator that uses its bottom row of fused teeth to carve out circular chunks of flesh. Clustered puncture wounds, on the other hand, are often signs of orca attacks; these marine mammals have been known to successfully hunt white sharks.
Other scars on a shark could suggest encounters with prey, parasites, rival sharks, or other behaviors. Shallow raking scars (1-5 lines long) might be caused by seals’ sharp claws, while delicate bite wounds could be signs of affection. During mating, white sharks grasp each other using their mouths, a behavior known as the mating hold. These bites often involve adjusting position by releasing and reapplying pressure, leading to repeated semi-circular bite marks. By the time researchers encounter these sharks off the California coast, these bites are usually healed or mostly healed, implying that mating occurs during the offshore phase. This information can help solve some of the mysteries that shark researchers strive to unravel.
This approach doesn’t stop at just the sharks off the coast of central California; it goes far beyond sharks and encompasses various species worldwide. By replicating this pattern of observation and categorization of injuries in different global regions, we might uncover unique wound patterns among diverse shark populations. Remarkably, similar scars can be spotted on other large marine creatures that share common prey, predators, and parasites, such as whales and dolphins.
