Dolabella brazieri from southern New South Wales

Here are some photos of Dolabrifera brazieri from southern New South Wales.

Two-Fold Bay, southern New South Wales, eastern Australia. March 1986 AM C149561. [animals ranged from 10-15cm long] Lower Left: showing head, Lower Right: showing opening into reduced mantle cavity. Photos: Bill Rudman

These photos illustrate a fairly typical specimen. It is much broader and flatter than a species of Aplysia and the relative large foot helps it to fasten firmly on to the rocky substrate. I guess it is the nearest thing to a 'limpet' within the Sea Hares. One of the most noticeable modifications is the fusing of the parapodia, except for a small gap. This makes a permanent 'parapodial chamber' which encloses the reduced shell and associated mantle cavity. The free part of the parapodial edge [lower right photo] forms a pair of valves and siphons which direct water in and out of the mantle cavity.

Best wishes,
