Blue-ringed octopus at Atmosphere Resorts & Spa Philippines - photo by Don Tan

I’ve been Atmosphere Resorts & Spa’s marine conservation biologist for 14 months now and I dive regularly. In fact, it’s unusual to see me with dry hair. Coming from a coral reef and megafauna (the BIG stuff) background, many of our critters I’ve excitedly encountered for the first time. However, there is one particular little 8-armed guy that I have yet to set my eyes on – the elusive (I recon “mythical”) greater blue-ringed octopus. Octopus can pop up at many of our dive sites. However, we have one particular site which, at certain times of the year, is your best bet …

Blue Ringed octopus by Donald Tan at Atmosphere Resorts & Spa Philippines

Octopus season is upon us! At least seven species are seen along Dauin’s coast (if you know where to look). However, there is more to these clever cephalopods than meets the eye. What you don’t know about octopuses… They’re related to your common garden snail Octopuses are members of the Phylum “Mollusca”, which puts them in the same mixing pot as snails, nudibranchs and scallops. All molluscs have some form of shell and bilateral symmetry (split them in half & the two sections appear the same). One heart just isn’t enough – they have 3! The main heart pumps blood …

Octopus sex at Atmosphere resort in Dauin, Dumaguete, Philippines

Octopus are one of the most interesting critters a diver can encounter while underwater. Whether the fact that they can squeeze into any crevice that their beak will fit into or that they can change color and texture in an instant, one of the most interesting things about octopus is actually their sex life. Octopus will begin to metabolize their own muscles when they become sexually mature to make their eggs and sperm. Because of this, almost all species of octopus lay one clutch of eggs and then die.   The male mototi, the one with the stripes, showing off …

Octopus October is officially in full swing. Every year we look forward to October because Cephalopods seem to infest the coast. This year they definitely got the message and have returned in full force! Although we found a Blue-ringed Octopus, Wonderpus, and five Flamboyant Cuttlefish on a dive in September, that was just a preview. Octopus October started on the first day of the month, with dive center manager Marco finding a Blue-Ringed octopus on the house reef which stayed around for a few days. Our current favorite dive site, Secret Corner, has exploded into life. We have encountered a …

Octopus October

Since I started working here in March, every month of diving at Atmosphere has been awesome, not only because of the guests and staff but also because of the amazing critters. That being said, for me personally, October has been exceptional. We have had many unique sightings this month and many guests have finally seen a desired critter for the first time, including the elusive Harlequin Shrimp! We are still seeing frogfish at a lot of the dive sites, so I’m definitely happy, and one of my favorite Giant Frogfish reappeared and it seems to have changed color from purple …
