Circular bites unlock offshore mating clues for great white sharks

Researchers from the California White Shark Project propose a systematic way to interpret scars on great white sharks, based on a 2025 Frontiers in Marine Science study. They cite a 16‑ft female great white with a circular head wound from a cookiecutter shark as an example, showing how scar patterns reveal interactions with prey, boats, mates, or entanglement. The team suggests offshore migration brings cookiecutter encounters and that certain scars—like hold bites that heal—could indicate offshore mating, helping scientists infer where and when white sharks reproduce.

Mysterious Bite Marks Found on Swordfish: The Culprit Revealed?

Fishers in Australia hauled in a swordfish covered in circular wounds caused by a pack attack from cookiecutter sharks. The swordfish, alive when caught, died shortly after. Cookiecutter sharks, known for their distinctive jaws, latch onto prey and scoop out chunks of flesh. These sharks, which grow to around 20 inches long, have been known to attack animals much larger than themselves, including great white sharks, whales, and even humans. The wounds on the swordfish were fresh, suggesting the attack occurred just before it was reeled in.

Mysterious Bite Marks Found on Swordfish: The Culprit Revealed?

Fishers in Australia caught a swordfish covered in circular wounds, which were identified as bites from cookiecutter sharks. The swordfish was alive when hauled onto the boat but died shortly after. Cookiecutter sharks, known for their distinctive jaws, latch onto prey and scoop out chunks of flesh. These sharks are found around the coast of Australia and Tasmania and have been known to attack animals much larger than themselves, including great white sharks and even humans. The sharks may use their light-producing organs to lure prey closer before ambushing and attacking.
