An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

Journal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

The complete mitochondrial genomes of two octopods Cistopus chinensis and Cistopus taiwanicus: revealing the phylogenetic position of the genus Cistopus within the order Octopoda. [PDF]

PLoS ONE, 2013
In the present study, we determined the complete mitochondrial DNA (mtDNA) sequences of two species of Cistopus, namely C. chinensis and C. taiwanicus, and conducted a comparative mt genome analysis across the class Cephalopoda.

Nodular Lesions in the Pyloric Caeca of Sardinella aurita (Teleostei) Associated With the Cestode Anthobothrium sp. 1 Larvae (Platyhelminthes: Eucestoda) Off Tunisia, Mediterranean Sea

Journal of Fish Diseases, EarlyView.
ABSTRACT Examination of round sardinella Sardinella aurita Valenciennes, 1847 (Clupeidae) from the Gulf of Tunis (Tunisia) revealed the first local and Mediterranean record of Anthobothrium sp. 1 sensu Jensen & Bullard, 2010 (Tetraphyllidea incertae sedis, Anthobothrium).

Thorson's rule, life‐history evolution, and diversification of benthic octopuses (Cephalopoda: Octopodoidea)

Evolution; international journal of organic evolution, 2018
Here, we evaluate the so‐called Thorson's rule, which posits that direct‐development and larger eggs are favored toward the poles in marine organisms and whose validity been the subject of considerable debate in the literature, combining an expanded ...

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 ...

A Generalizable Tool for Predicting Developmental Phenology for Wild Ecotherms

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Custom hatch timing models developed for four North American Lithobates frog species. Models are parameterized from Moore (1939). Panels (A, B) shows differential developmental rates under varying thermal regimes and G × E interactions. ABSTRACT Development in poikilothermic organisms is strongly temperature‐dependent, particularly during early life ...

Paleomagnetic Constraints on the Separation of the Olongbuluke Block From the North China Block During the Late Cambrian–Middle Ordovician and Its Tectonic Significance

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The collisional evolution of the micro‐blocks in the northeastern Tibetan Plateau is relatively well constrained. However, the reason why a fragment of the North China Block, the Olongbuluke Block, became separated from North China by the Central Qilian Block (a fragment of the South China Block) remains unclear.

The Spatiotemporal Patterns and Environmental Effects of Pelagic Communities in the Northwest Pacific Ocean Based on Sound Scattering Layer Descriptors

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This study developed generalized additive models using SSL descriptors, providing an innovative approach for analyzing relationships between marine environmental variables and pelagic community distributions. ABSTRACT The sound scattering layer (SSL) plays an important role in maintaining the structure and functioning of marine ecosystems.

Complete mitochondrial genome of the Loligo chinensis

Mitochondrial DNA. Part B. Resources, 2017
In this study, we determined the complete mitochondrial genome of Loligo chinensis. The genome was 17,353 bp in length and contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 3 main non-coding regions.
