About Panjang Reef

This reef contains one of the most appreciated scuba diving sightings if you are particularly observant and luck is on your side. The amazing bright yellow blue-ringed octopus dwells here. It is amazing how tiny and deadly this creature is. Fully grown adults reach the size of half of your thumb, and contain one of the most toxic poisons to be found in the sea.
