Traumatic Oral Lesions in Loggerhead Sea Turtles (Caretta caretta) Linked to Polychaete (Laetmonice cf. hystrix) Ingestion: A Case Report from the Northern Adriatic Sea [PDF]

open access: yesAnimals
Oral cavity lesions in sea turtles, particularly Caretta caretta, are relatively rare, and are typically linked to infectious agents as well as anthropogenic factors, including ingestion of marine debris or fishing gear.

A review of types of feeds used in polychaete culture [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2022
Polychaete serves as aquafeed for most aquaculture species and as bioremediation agent of organic waste. Polychaete used for broodstocks of finfish and crustaceans stimulates gonadal maturation and endocrine system in penaeid shrimp, therefore ...

First records of Brada kudenovi Salazar-Vallejo, 2017 (Annelida, Flabelligeridae) from Japan [PDF]

open access: yesCheck List, 2020
We reassess two specimens, part of the late Dr Minoru Imajima’s collections, from Japan of the flabelligerid genus Brada Stimpson, 1853. We re-identify the specimens as B. kudenovi Salazar-Vallejo, 2017 and newly record this species from Japan,

Acaenoplax — polychaete or mollusc? [PDF]

open access: yesNature, 2001
Palaeozoic invertebrate fossils may pose severe problems in assigning them to Recent taxa. Sutton et al.1 describe the beautifully preserved and illustrated Silurian fossil Acaenoplax hayae as a “plated aplacophoran” mollusc, interpreting its polychaete-like characters as convergent features.

First record of growth patterns in a Cambrian annelid

open access: yesRoyal Society Open Science, 2023
Early annelid evolution is mostly known from 13 described species from Cambrian Burgess Shale-type Lagerstätten. We introduce a new exceptionally well-preserved polychaete, Ursactis comosa gen. et sp. nov., from the Burgess Shale (Wuliuan Stage).

Reproductive morphology and redescriptions of some Neanthes Kinberg, 1865 (Annelida: Nereididae) species from the southeastern Asian seas, with comparative synoptic tables of accepted species

open access: yesThe European Zoological Journal, 2021
Neanthes Kinberg, 1865 is a speciose nereidid genus with some species exhibiting epitoky during the timing of reproduction. The epitokal morphology of males and females has long been agreed to be diagnostic to distinguish species.

The Current State of Eunicida (Annelida) Systematics and Biodiversity

open access: yesDiversity, 2021
In this study, we analyze the current state of knowledge on extant Eunicida systematics, morphology, feeding, life history, habitat, ecology, distribution patterns, local diversity and exploitation. Eunicida is an order of Errantia annelids characterized

A new southern record of the holopelagic annelid Poeobius meseres Heath, 1930 (Flabelligeridae) [PDF]

open access: yesBiodiversity Data Journal, 2020
The unusual holopelagic annelid Poeobius meseres Heath, 1930 (Flabelligeridae) was first collected from Monterey Bay, California, and has been subsequently recorded across the northern Pacific from Japan to the Gulf of California. Rare occurrences in the

Gyrochorte “highways” and their environmental significance in shallow-marine sediments [PDF]

open access: yesActa Palaeontologica Polonica, 2020
The reworking of a trace by a subsequently following organism represents a so-called sequorichnial behavior and leads to formation of a “burrowing highway”. Burrowing highways occur more frequently than assumed in the fossil record.
