Shark in Chinese / Japanese...

鮫 means shark in Japanese in a single Kanji. 鮫 is often used in Japanese along with a Kanji adjective. This would be the base Kanji for titles like “Tiger Shark,” “Hammerhead Shark,” “Thresher Shark,” etc.

This character can be pronounced in Chinese but is only used in combination with other characters to create shark-related titles. This Kanji is best if your audience is Japanese.

鯊魚 means shark (literally “shark fish”) in Chinese.

This single Chinese character means shark.

However, in Japanese, it can refer to the family of goby fish.

鯊 is good if you're looking for the word shark in Chinese and Japanese folks might misunderstand it.
