Among the showcased creatures in Zhang's exhibition are organisms ranging from a few millimeters to 1.5 meters in size, including images of batfish feeding, deep-sea shrimp molting and the momentary stillness of swiftly swimming sailfish.

"For humans, the ocean holds countless unknowns. I enjoy exploring the unknown, and photography is a great way to showcase the marine world as I see it," said Zhang, who grew up in Hainan and developed a deep connection to the ocean through island life. Despite being described as hyperactive in his youth, Zhang could spend two days sitting by the beach observing the subtle differences between the seashells and pebbles.
