We were fortunate to observed the birth/hatching of this Flamboyant Cuttlefish - Metasepia pfefferi.
The eggs were glued inside a sea shell. After hatching, it rested on the shell for a while, before swimming/floating to the water column.
I didn't get to capture the moment of birth/hatching on this particular encounter, however, 2 days later, when we were doing a night dive at the same dive site, the dive guide found another batch of eggs, 3 of them and I can see the embryos were well developed and already swimming inside the eggs. We waited patiently for the hatching and eventually, I was able to capture the moment in video. Check out the video here :
"Metasepia pfefferi", also known as the flamboyant cuttlefish, is a species of cuttlefish occurring in tropical Indo-Pacific waters off northern Australia, southern New Guinea, as well as numerous islands of the Philippines, Indonesia and Malaysia. The flesh of this colorful cephalopod contains unique acids, making it unsuitable for consumption.
