The Type A Ko-hyoteki class was a class of Japanese midget submarines (Kō-hyōteki) used during World War II. They had hull numbers but no names. For simplicity, they are most often referred to by the hull number of the mother submarine. Thus, the midget carried by I-16-class submarine was known as I-16's boat, or "I-16tou."

The following index is provided as an overview of and topical guide to Wikipedia's articles on recreational dive sites. The level of coverage may vary:
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes.
