As you arrive at San Benedicto in the Revillagigedo Islands, Silky sharks (Carcharhinus falciformis) come in to circle the boat.
The Silky shark (Carcharhinus falciformis) is one of the most common sharks at the Revillagigedo Islands.
Diving with Demoiselles
Few people but New Zealand scuba divers will understand my fascination with a slightly boring silver fish with two white spots. Those who've been completely immersed in a school of Demoiselles, surrounded in all directions, fish so close you could cradle them in your hands, will get it.
Taak Bi Ha
Cenote Taak Bi Ha has opened up for cave diving, snorkelling and swimming since our last Mexico cave diving trip. It has a stunning closed cavern that they light up for visitors. Taak Bi Ha is part of cave system Sac Actun.
Tank Cave - A3 intersection
Coming from the entrance of Tank Cave, this is the point at which the tunnels split. The A Tunnel leads off to the left and the C Tunnel continues straight ahead.
Tank Cave - F Tunnel
Deep in the bowels of Australia's Tank Cave is a beautiful long straight tunnel called F Tunnel, stretching for a couple of hundred metres.
Tank Cave - C Tunnel
As tunnels fan out from the Tank Cave entrance they are named off by letter: A, B, C, D etc.
Tank Cave at D2
This floor to ceiling feature leftover from when water eroded out the passages of the cave that cave divers now swim through is a favourite of mine.
Tank Cave ice chamber
Local cave divers will know this room in Australia's Tank Cave by the inspirational name "90 Metre Room". I like to think of it as an ice chamber with a molten ceiling. It definitely feels icy on a smoking hot Australian summer's day!
