Amoria ubdulaata Sowerby 1864 extreme low tide, St. Vincent Gulf, South Australia, Australia
With its elegantly proportioned curves and delicate undulating pattern of fine lines, a decentt size and high gold Amoria undulate is a most beautiful shell.
Amoriia undulate is a member of the family Volutidae. Its common name is Wavy Volute. It is carnivores eating mainly small sea snails.
There are multiple specie of Amoria that can be collected in southern Australia. where they inhabit the tidal flats where they breed. Australia is known for its extensive tides that leave huge amounts of the bottom surface exposed at low tide, even more so on the extreme low tides. Amoria undulate like many others in its family live at the far end of the tidal bank. They are not found close to the shore. After breeding season they migrate to deeper water.
To collect one has to watch the tide table and wade out a long distance in hopes to collect, alway keeping an eye on the cock so as not to get drowned by the surging incoming tie. Hence, these shells don’t show up all that often in collections.
This specimen was donated by Richard Kent who obtained it from a South Australian shell dealer/collector. It is solid and full adult. It would be graded as a gem. It would be a standout in any collection!
