Description:
Diving survey was conducted on the mysterious sea knolls discovered in the southern part of the
Yatsushiro Sea, Kagoshima, Japan. The sea knolls are 50 meters in diameter and 5 meters in relief, and 88 knolls are discovered in close proximity.
A diving survey to reveal the nature of these knolls was conducted in February 2009. The most upper
layer of the sea knoll is composed of sand and the surface is covered by the colony of a kind of oyster,
“Hyotissa imbricata”. We proposed seven hypotheses for the origin of these knolls, although any clue sup
porting these hypotheses was not obtained.
