Giant Squid Tentacular Club Suckers and Teeth | Ogasawara, Japan
Close-up view of the suckers on the tentacular club of an Architeuthis giant squid. I recovered this squid arm after seeing a sperm whale (Physeter macrocephalus) breach in the waters around Ogasawara, Japan (the Bonin Islands). Note the sharp, serrated teeth that line the edge of the suction cups. These are made of chitin, and help the squid to grasp and secure prey.
