Morphological and molecular characterization of Pleopodias species (Isopoda, Cymothoidae) collected from Japanese waters [PDF]

Nauplius
Cymothoidae are parasitic isopods that infest fishes inhabiting marine, brackish, and freshwater environments. The cymothoids of the genus Pleopodias Richardson, 1910 are crustaceans that parasitize on the body surface of fish.

Do Parasite Effects on Fish Body Condition Depend on Host Size and External Temperature? A Meta‐Analytic Approach

Journal of Zoology, EarlyView.
Evaluating relationships between host body condition indices (BCIs) and parasite infections is a common approach for assessing the negative effects of parasites on host health. Researchers generally expect negative correlations between BCIs and infection levels; however, empirical results are often highly variable among host–parasite systems.

Filter feeders living on suspension feeders: New insights into the lifestyle and distribution of Arcturidae Dana, 1849 (Crustacea: Isopoda) around Iceland

Marine Ecology, EarlyView.
Abstract The focus of the present study was on arcturid isopods occurring in the subarctic region around Iceland. Data from two decades of sampling with an epibenthic sledge (EBS) during numerous expeditions of the BIOICE (Benthic Invertebrates of Icelandic Waters; 1992–2004) and IceAGE (Icelandic marine Animals: Genetics and Ecology; 2011—ongoing ...

A new species of endoparasitic isopod, Portunion sinensis sp. nov. (Isopoda: Entoniscidae), found in the mud crab Scylla paramamosain in China

Frontiers in Marine Science
Portunion (Isopoda, Epicaridea, Entoniscidae) is an extremely rare endoparasitic isopod genus that is found mainly in the blood cavity of decapod crustaceans, such as true crabs and hermit crabs.

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

MEDITERRANEAN SEA FRY; A SOURCE OF ISOPOD INFESTATION PROBLEM IN EGYPT WITH REFERENCE TO THE EFFECT OF SALINITY AND TEMPERATURE ON THE SURVIVAL OF LIVONECA REDMANII (ISOPODA: CYMOTHOIDAE) JUVENILE STAGES. [PDF]

Journal of the Egyptian Society of Parasitology, 2019
Parasitic isopods have received considerable attention as they cause series impacts on their hosts either alone or with other environmental stresses such as water pollution. The present study investigated the infestation status with isopods among the fry

First Report on the Diet of the Angolan Flying Squid (Todarodes angolensis) in New Zealand Waters

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The Angolan flying squid (Todarodes angolensis) is a southerly distributed, large‐bodied ommastrephid preyed upon by many large marine vertebrates such as the southern elephant seal and deep‐sea squalid sharks. Here, we report its diet in New Zealand waters for the first time, identifying prey items from the stomach contents of 58 adults using ...
