The Zoo

Guides named this site for the crowd it draws, and on a running tide the label holds: whitetip reef sharks cutting between the heads, schools of surgeonfish and snapper stacked along the ridges, barracuda hanging up-current, and the occasional eagle ray gliding the sand breaks. The terrain is a series of coral ridges the flow combs like a hedgerow, soft corals open and feeding. It is a dive for keeping your head moving — the strait delivers traffic from every direction. Fish density varies with the tide phase more than the season, so trust the operator's timing over any calendar.

The moment you come for: Reef-shark and schooling-fish traffic on the tide; ridge-and-channel terrain; a reliable action counterpoint to the strait's coral walls.

Topography: Current-swept coral ridges and heads with sandy breaks in the Somosomo Strait

Current: One of the strait's fishier corners precisely because water moves through it.

Entry: Live-boat drift entry timed to the tide, like most Somosomo Strait sites.

Hazards: Current strength varies dive to dive; separation is the main risk — stay on the guide's line.

Conservation: Drifting divers cover ground fast — keep buoyancy dialed so the ridge tops pass beneath you, not against you.

Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
