Cooke’s Orobophana Snail (Orobophana cookei)

Cooke’s Orobophana Snail was described in 1934, it was apparently restricted to a cliff on the west side of the beautiful and often photographed Kalalau Valley on the island of Kaua’i, Hawaiian Islands.

The shells of this quite large species reach sizes of about 0,56 cm in height and 0,6 cm in diameter. [1]

Since all Kauaian helicinid snails are now thought to be extinct altogether, this species must be considered extinct too. [2]
