(In press) Polydora websteri and P. haswelli (Polychaeta: Spionidae) confirmed as mudblister worm species in New Zealand shellfish. New Zealand Journal of Marine and Freshwater Research 38: .
Relevant content: P. haswelli appears near identical to, and may be the senior synonym of a recently-described North American shell borer, P. neocaeca Williams and Radashevsky. P. haswelli has been found on subtidal Pecten novaezelandiae scallops as well as co-existing with intertidal P. websteri on oysters.

(In press) Shell-blister damage in cultured Perna canaliculus mussels and the role of Polydora haswelli (Polychaeta: Spionidae). New Zealand Journal of Marine and Freshwater Research 38: .
Relevant content: Polydora haswelli is here reported from the Coromandel Peninsula, for the first time occurring as a shell occupant and blister-inducer inside Perna canaliculus mussels cultured on longlines. Penetration to the extrapallial space is by a perpendicular shaft, typically of figure-8 to letter-B shaped section, and usually sited at an exterior shell flaw (growth check) in the mussel shell.
Some biological information might be found in the Polydora haswelli taxonomic literature.
