HSK6 Standard Course 6上, chapter 19.
I'm not too sure about how to pronounce 蛤 above:
CC-CEDICT: 蛤 (gé) clam; (há) frog / toad
The HSK6 textbook comes with a recording where it's pronounced gé, and the previous page shows a photo of a 蛤蜊 (gélí) = "clam", including the pinyin. However, Chinese Zero to Hero (screenshot) pronounces it há in both the audio and the pinyin, which suggests this might be an acceptable alternative. Indeed, this YouTube video says gé but writes há.
Question: In the context of deep-sea exploration, what is the pronunciation of 蛤?
