Blanket Octopus - Tremoctopus violaceus
Not definitely sure of the ID but several sightings of Blanket Octopus during Black Water Dives in Anilao have identified them to be Common Blanket Octopus Tremoctopus violaceus. The picture shows a juvenile female, body size around 1.5 cm, tentacles are much longer. The degree of sexual dimorphism in Blanket Octopus is very high, with females growing up to two meters in length, whereas males, grow to about 2.4 cm. This one seen last night has a body size of around 1.5 cm.
There have been several sightings of huge size (1-2 meters) female Blanket Octopus in Anilao and they are super impressive. Check out this video footage of a female from Romblon Island, Philippines :
Hope to see one like this in the near future.
