Octopuses have an amazing ability to squeeze through tiny crevices, cracks and holes. My fall BIOS independent studies student, Raymond Deckel is investigating just how small a hole Octopus macropus can fit through as well as how long it takes them to squeeze through different sizes of holes. CAABS intern Rowena Day, NSF-REU intern Jared Kibele as well as teaching assistant Abel Valdivia help wrangle the 232 g octopus, Ray times its escape through a one-inch hole while I shot video clips for later analysis.
