I was looking for photos of antarctic sleeper sharks (Somniosus antarcticus) because I am preparing a talk about Architeuthis I´ll do at the end of the month. There are only quite few photos online of this species, especially of large specimens. As you know, beaks of Architeuthis and Mesonychoteuthis were found in the stomaches of this sharks, but it was not sure if they actively hunted them or just scavenged dead or dying specimens. I found at fishbase a quite interesting photo of an antarctic sleeper shark of 180 cm caught off the Falkland Islands as by-catch of Pataginian toothfish, which has some clear and comparably big sucker marks and a lot of scratches. Could it be possible that this are sucker marks of Mesonychoteuthis? I think this is really rather interesting, because it shows there actually is interaction between antarctic sleeper sharks and big squids.
