Freshly caught 30 feet off the dock. Yummy!
Octopus about 18cm. Swam past as I was walking through shallow water
Octopus (first I've ever seen in wild), swimming rapidly across pool between rocks, then landing on bottom, then retreating behind seaweed.
Under a large rock in wasteland area.
washed up on beach
Dead on sandy beach. About 1 m in length.
My first and only sighting of an octopus on tiri. It was travelling along the seabed off the end of the jetty. There was absolutely no ripple on the water - you could see straight down to the bottom with no distortion, have never seen it like that since.
Kerry-Jayne Wilson wrestled this large octopus out from under a ledge in a large tide pool for the students to see. It then slithered back home, none too pleased with the attention. It was a magnificent animal.
Here are two shells of a rare species of Nautilus, Nautilus scrobiculatus, known as Crusty Nautilus. It has a restricted range in Papua New Guinea.
Since I do not know its collection data and locality, I'm stating here when I observed these shells at the Academy of Natural Sciences of Philadelphia (now of Drexel University).
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural κεφαλόποδα (kephalópoda); "head-feet"). These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishermen sometimes call them inkfish, referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology.
