Researchers have described a new species of sea slug discovered off the coast of northern Taiwan. The tiny creature, smaller than a sesame seed, was named Thecacera sesama after its distinctive markings.
The translucent nudibranch measures less than three millimeters long and features black and yellow patterns. It was first spotted in 2019 by Ho-Yeung Chan during a recreational dive near Keelung while he was an undergraduate student at National Taiwan Ocean University.
