What was the seaweed shot with?

Underwater professional camera. Algae protozoa are a kind of eukaryotes. The shapes of algae are slender, massive, saddle-shaped and spherical. The shape of cells can be divided into several forms, such as truncated, oval, oblanceolate and so on. There are many kinds, and you need a professional camera to shoot clearly. Seaweed lives in seawater, so cameras need to be waterproof. The professional underwater camera has 2 million to 5 million pixels, and the underwater photos taken at night are clear. So the algae were photographed underwater with a professional camera.
