A social group of 6 sperm whales / giant squid in mouth

-- VIDEO REMOVED -- I've removed the video at the suggestion of a friend of mine, who tells me that it is worth real money. Contact me privately if you are interested in the footage.

Above is a video of six sperm whales (Physeter macrocephalus) in the Ogasawara Islands, Japan. The lead female sperm whale has the remains of a large squid (possibly, an Architeuthis giant squid) in her mouth. 15 minutes earlier, we had been in the water in the scattered remains of the squid (birds were feeding on it) before seeing this group of sperm whales close by. It looked as if the squid had been torn apart on the surface!

Here's a photo of part of the squid, which we found and brought back onto the boat:

The arm bit is probably between 4-5 inches long, and each sucker on it had clearly-visible (and sharp!) teeth lining the rim.

Here's another shot of a cephalopod carcass we found floating around near sperm whales a couple days earlier. This time, it was a large octopus:

Tony Wu speculates that it is a seven-arm octopus (Haliphron atlanticus), but we need an expert's opinion on this.
