Endemic subspecies in Ongeim'l Tketau (Jellyfish Lake), snorkel only. The population crashed to near-zero during the 2015-16 El Nino drought and subsequently recovered; encoded 'shoulder' throughout rather than 'peak' because numbers have proven volatile and current status was not verified. Do not build a trip around it without checking.

Diveable all year with no closure. Jun-Sep is the wet season with rougher seas, visibility down to 15-20m, and exposed sites like Peleliu frequently cancelled, hence 'limited'. Dec-Apr is dry season with 40m+ visibility and is also the manta window.
