What are some record-breaking biological discoveries of 2022?

Biggest single-celled bacterium
Averaging about a centimeter long and visible to the naked eye, Thiomargarita magnifica, is a newfound bacterium, which lives in the mangrove forests of the Caribbean’s Lesser Antilles, is about 50 times larger than other species of big bacteria and about 5,000 times larger than typical bacteria. Why this species evolved into such a giant is unknown.

Largest fish colony 🐟
Deep off the coast of Antarctica, a breeding colony of some 60 million nests of Jonah’s icefish (Neopagetopsis ionah) is stretching across at least 240 square kilometers of seafloor.

The world's smallest new snail species 🐌
In Southeast Asia, scientists discovered two new snail species, smaller than any seen before. They dubbed the smallest one, measuring only 0.6 millimeters in diameter, Angustopila psammion, as “psammion” derives from the ancient Greek word for “grain of sand.”
