Griffith University science students, Kris and Tim managed some amazing night shots of our native snails out and about in Mt Glorious, south-east Queensland during their studies of snail populations of this rainforest area.
Photos were taken by Ben Revell and show Thersites richmondiana and Sphaerospira fraseri on their nocturnal journeys. Richmondiana is enjoying a feast on a fungus, one of our native snails’ favourite foods.

This beautiful Tasmanian snail Attenborougharion rubicundus was named in honour of Sir David Attenborough. This colourful semi-slug’s usual habitat is restricted to a small area of south-east Tasmania in wet forests on the Tasman and Forestier peninsulas. The species was first described in 1978 and classified in the genus, Helicarion. However, recent work by the Australian Museum scientists have shown it is a separate genus.
This is the first genus to be named after Sir David who already has been named in 12 species.
During this visit to Sydney in early February, 2017, he was honoured by being named patron of Australia’s first museum, The Australian Museum.
Here are some of our beautiful helicarionids [semi-slugs and glass snails] from eastern Australia.

63 Earlyactors and Interactors spent time with the Snail Whisperer at the recent Earlyact/Interact Conference for Rotary District 9600 at Caboolture, Queensland. Sharing what they wrote:
Congratulations to 1C at Samford State School – our newest Junior Snail Whisperers. They have been learning about nocturnal and diurnal animals in science and have found out that snails are mainly nocturnal but have many interesting features!

Found by Brian Hawkins of ABRS Bush Blitz, this beautiful semi-slug [F. Helicarionidae] was found in the Brindabella Ranges.
The Brindabella Range, commonly called The Brindabellas, is a mountain range located in Australia, on a state and territory border that separates New South Wales and the Australian Capital Territory.
Most people’s first interaction with snails and slugs is of those that are eating their plants, their crops or the vegetables in their garden. Sometimes, the culprits can’t be found as these animals, often slugs, bury themselves in the soil during the day and only come out when conditions are more favourable at night.
Our native snails are NOT vegetarian. They eat fungi, micro-algae on the leaves of plants and biofilm on most surfaces. Some are carnivorous and will even follow the slime trail of other snails to have a feast.
The major problems in our backyard gardens are two species:
- The common garden snail or European Garden Snail, Cornu aspersum, which is related to the ones that are eaten there in huge quantities. These can, with careful preparation, be eaten also but are farmed at the Glasshouse Mountains at Glasshouse Gourmet Snails.
- The Asian Tramp Snail, Bradybaena similaris which is serious vine and market garden pest, has become well-established in eastern Australia.
- Our largest land snail, the Giant Panda Snail (Hedleyella falconeri), happily searching for food in the rainforest. It won’t eat your garden.
Australian land snails are almost always dextral i.e. they have a right hand opening. A few rare species are sinistral [left hand opening]
