Costão da Jaconema - Deck Pous Nautilus (Ilha Grd RJ)

Jaconema, affectionately known by us as the 'Pous Nautilus Deck,' is a classic Arraial dive that often gets overlooked, but really shouldn’t. It’s a rocky coastline site, shallow enough for newer divers but with plenty to keep experienced eyes busy, especially on a night dive. The maximum depth sits around 9m, so you get good bottom time here. We love dropping in and immediately looking for the small-scaled spinycheek sleepers nestled in the cracks. Keep an eye out for orangespotted and pygmy filefish, they're surprisingly common here, flitting between the rocks. Visibility averages about 7m, which isn't 'gin-clear' by any means, but it’s more than enough to appreciate the details. On night dives, the place absolutely comes alive. We’ve had incredible encounters with octopuses and squid hunting in the beam of our lights – a totally different vibe from the daytime. Our pick for a truly unique experience here? Definitely the night dive. You’re practically guaranteed to see something cool.
