The exotic mollusks, known as “wandering meatloaf,” have teeth made of a rare material Iron Minerals, previously only found along rocky coasts, according to a new study.
Researchers have discovered a rare iron ore – called santabarbaraite – in the teeth of the rock-grazing mollusks Cryptochiton stelleri, Nicknamed the “meatloaf wandering” because it looks like an oval-shaped, reddish-brown body, reaching 14 inches (36 cm) in length.
This discovery shines a light on how C. Stillry Researchers said it could scrape food off rocks. ” [Santabarbaraite] It contains a high percentage of water, which makes it a low-density solid. Lead author Dirk Joyster, associate professor at Science Materials and Engineering at Northwestern University in Illinois, He said in a press release.

The wandering meatloaf that has the names too The giant Pacific chiton and the giant chiton on rubber feet, Is the largest known species of ketone, and it is a marine mollusk with a flat oval body that has a shell made of overlapping plates, like bed bugs. Ketones are known for their remarkably hard teeth, which are associated with the soft, flexible ringing of the tongue. While foraging for food, ketones scratch their tooth-covered radiola on rocks, in order to capture algae and other foods.
Joester and his colleagues had previously studied ketone teeth, but they wanted to learn more about the plank – the hollow, human tooth root-like structure that “connects” [chitons’] The researchers wrote in the study that the tooth head is very rigid with a flexible membrane. They do this by analysis C. Stillrychompers with some high tech Technique, Including a synchrotron light source and transmission electron microscope.
These analyzes revealed santabarbaraite in the upper portion of the ketone. “This mineral has only been observed in geological samples in very small quantities and has never been seen before in a biological environment,” said Joyster.
The researchers said the discovery demonstrates how this strange meatloaf uses its teeth completely, not just the extremely stiff and durable cup for gathering food.
Next, the team attempted to recreate the chemical composition of the pen using ink designed for 3D printing. The study’s first author, Linus Stegbauer, a former postdoctoral fellow in Joester’s lab, developed the ink with iron and phosphate ions mixed with a biopolymer derived from ketone teeth. Stegbauer, now a senior researcher at the Institute for Interprocess Engineering and Plasma Technology at the University of Stuttgart in Germany, and his colleagues found that the experiment worked – the ink printed materials that are so tough, tough and durable, so long as scientists mixed right before printing.
“Nanoparticles are also formed in Biopolymer“It gets stronger and stickier,” said Joyster. This mixture can then be easily used for printing. Subsequent air drying results in the final solid and solid material. ”
The study was published online Monday May 31 in the journal Proceedings of the National Academy of Sciences.
