Winston F. Ponder (born 1941) is a noted malacologist from New Zealand who has named and described many marine and freshwater animals, especially micromolluscs.He graduated with an MSc, PhD and DSc from the University of Auckland, New Zealand.
Ponder was the principal research scientist in the malacology section of the Australian Museum, Sydney, Australia and helped to build up the museum's mollusc collection so that it became one of the most extensive of its kind in the world. Ponder retired from this post after a long career of more than forty years of research on molluscs, and is now an Honorary Fellow.
He has been the president of the Society of Australian Systematic Biologists, and was the managing editor of the journal Molluscan Research of the Malacological Society of Australasia.for 8 years.
Early in his career, in 1964, he worked on Antarctic collections together with Richard Dell and Alan Beu, resulting in a major monograph on the Antarctic bivalves, chitons and scaphopods.
Ponder is the author of more than 300 research publications. Many of these are on the subjects of the freshwater molluscs of Australia, and on invertebrate conservation. One major contribution was a taxonomy of the Gastropoda, which he published together with David R. Lindberg in 1997.This was the last major publication on the taxonomy of the Gastropoda that was based on the morphology of snails and slugs (their internal and external shapes and forms), and did not take into account any analysis of their DNA or RNA.
In 2008, again with David Lindberg, he edited the book "Phylogeny and Evolution of the Mollusca"in which 36 experts provided an up-to-date review on the evolutionary history of the Mollusca, based on reinvestigation of morphological characters, molecular data and the fossil record.
In 2008 Ponder received the Australian Marine Sciences Association Silver Jubilee Award for a lifetime of achievement in research on marine molluscs.
In 2009 he was awarded the Clarke Medal in recognition of his Zoological work by the Royal Society of New South Wales.

Heterobranchia, the heterobranchs, is a taxonomic clade of snails and slugs, which includes marine, aquatic and terrestrial gastropod mollusks.
Caenogastropoda is a taxonomic clade, a large diverse group which are mostly sea snails and other marine gastropod mollusks, but also includes some freshwater snails and some land snails. The clade is the most diverse and ecologically successful of the gastropods.
Turbonillinae is a subfamily of mostly minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.
Cingulinini is a taxonomic tribe of very small sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Sayellini is a taxonomic tribe of minute ectoparasitic sea snails, marine gastropod molluscs, or micromollusks, in the very large family Pyramidellidae, the pyrams and their allies.
Syrnolininae is a subfamily of minute parasitic sea snails, marine heterobranch gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.
Eulimellini is a tribe of minute sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.
Tiberia is a genus of minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies. Tiberia is the only genus in the tribe Tiberiini.
Odostomellini is a taxonomic tribe of minute sea snails, marine gastropod molluscs within the family Pyramidellidae the pyrams and their allies.
David R. Lindberg is an American malacologist and professor of integrative biology at the University of California, Berkeley. He is also the Curator for the University of California Museum of Paleontology and co-editor of the journal Molecular Systematics and Phylogeography of Mollusks.
Thiaridae, common name thiarids or trumpet snails, is a family of tropical freshwater snails with an operculum, aquatic gastropod mollusks in the superfamily Cerithioidea.
Naticidae, common name moon snails or necklace shells, is a family of minute to large-sized predatory sea snails, marine gastropod molluscs in the clade Littorinimorpha. The shells of the species in this family are mostly globular in shape.
Lithoglyphidae is a family of small freshwater snails with gills and an operculum, aquatic gastropod mollusks.
The taxonomy of the Gastropoda, as revised by Winston Ponder and David R. Lindberg in 1997, is an older taxonomy of the class Gastropoda, the class of molluscs consisting of all snails and slugs. The full name of the work in which this taxonomy was published is Towards a phylogeny of gastropod molluscs: an analysis using morphological characters.
Vetigastropoda is a major taxonomic group of sea snails, marine gastropod mollusks that form a very ancient lineage. Taxonomically the Vetigastropoda are sometimes treated as an order, although they are treated as an unranked clade in Bouchet and Rocroi, 2005.
The Ptenoglossa is an informal taxonomic group of sea snails. This group was considered paraphyletic or polyphyletic by Ponder and Lindberg (1997) in their classification of gastropod molluscs.
Seguenzioidea is a superfamily of minute to medium-sized sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Modulidae, common name modulids, is a family of small sea snails, marine gastropod molluscs in the superfamily Cerithioidea.
Scaliolidae, common name scaliolids, is a family of minute sea snails, marine gastropod molluscs or micromollusks in the superfamily Cerithioidea, the ceriths and their allies.
This overview lists proposed changes in the taxonomy of gastropods at the family level and above since 2005, when the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) was published. In other words, these are recent updates in the way various groups of snails and slugs are classified.
