Biyadoo Housereef

You can snorkel and scuba dive at Biyadhoo's house reef. A flat 50 to 200 m wide, depending on the stretch, leads to the reef wall. Passages numbered 1 to 7 on the map were dug into the flat and give direct access to the wall.

On the flat, green turtles are often seen feeding, and there are fish that prefer this area, such as juvenile triggerfish, wrasses and snubnose pompano. On the wall there are groupers, notably the yellow-edged lyretail and the bluespotted grouper, as well as octopus and squid. The regal angelfish appears on the reef wall. Huge redtoothed triggerfish are frequently seen at Biyadhoo. Besides the common reef fish, there are clownfish, batfish, huge schools of sergeant major, bannerfish, lionfish, boxfish and parrotfish.

Among the invertebrates are crown-of-thorns starfish, sea clams, Christmas tree worms and sea slugs. The house reef also has eagle rays, stingrays, octopus, sea stars and sea cucumbers. The warming of the water during El Niño killed most of the corals on the house reef. There are signs of recovery, with corals growing back, but the process is slow.
