Brachyuran Crab <i>Halicarcinus planatus</i> from the Beagle Channel

Caption

The brachyuran crab Halicarcinus planatus from the Beagle Channel, south of Tierra del Fuego, is shown. This adult female has recently moulted. Oocytes and other internal structures are visible through the carapace, which is 15 mm wide. Inset shows a preserved, adult-sized female of the same species discovered at Deception Island, Antarctica in 2010. That crab's carapace is 12 mm wide, and its fifth-left walking leg (pereiopod) separated after it was collected. Images taken by S.T.
