Architeuthis Giant Squid Feeding Arm | Ogasawara, Japan
Photographer Douglas Seifert holding a 351-centimeter segment of a Architeuthis giant squid feeding arm, displaying the suction cups lining the tentacular club. The suction cups have sharp, serrated teeth that help the giant cephalopod hold on to its prey. I recovered this giant squid arm segment after seeing a sperm whale (Physeter macrocephalus) breach. Photographed in Ogasawara, Japan.
