DSC_2910 Encrusted limpet, or ruharu (Patellioda corticata) underside, (on left), compared with Siphon limpet, or ngakihi awaawa (Siphonaria australis) on right. These two animals are frequently confused because of their similar shells. Aquarium Point, Otago Harbour *
DSC_0697 Siphon limpet (Siphonaria australis) very similar to Patellioda limpets, but if you push Siphonaria at low tide they wiggle because as seen here they cannot pull their whole body inside the shell. Cat's Eye Point, Kakanui *
