In Japan ika (squid) is very fresh and even during days when the Tsukiji is closed you’ll find delivery of fresh squids. I purchased this from a fish monger and when I dissected it, I discovered the stomach was full of sand.
These squid feeds primarily on small fish, crustaceans, and use its barbed tentacle suckers to grab its prey and slices and tears the victim’s flesh with its beak and radula.
They often approach prey quickly with all ten appendages extended forward in a cone-like shape. Upon reaching striking distance, they will open their eight swimming and grasping arms, and extend two long tentacles grabbing their prey and pulling it back towards a parrot-like beak, which can easily cause serious lacerations. These Two longer tentacles can reach full length, grab prey, and retract so fast that almost the entire event happens in one frame of a normal speed video camera. Each of the squid’s suckers is ringed with sharp teeth, and the beak can tear flesh, although they are believed to lack the jaw strength to crack heavy bones.
