Mussels, Perna canaliculus, as biosensors for climate change: concurrent monitoring of heart rate, oxygen consumption and gaping behaviour under heat stress

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1621-1639, December 2025.
ABSTRACT The green‐lipped mussel, Perna canaliculus, is an important aquaculture species in New Zealand. Recently, the industry has been increasingly challenged by stressors associated with climate change. Predicting its response to climate change requires more than single‐parameter measurements, as mussels show various physiological and behavioural ...

Animal medical systems from Apis to apes: history, recent advances and future perspectives

Biological Reviews, Volume 100, Issue 6, Page 2608-2624, December 2025.
ABSTRACTAnimal medical systems encompass a wide range of behaviours aimed at maintaining or improving health. It has become clear that these behaviours are not limited to animals treating themselves (self‐medication) but also include the treatment of group members, resulting in the adoption of the more inclusive term “animal medication”. Behaviour with

Associations between fishes (Actinopterygii: Teleostei) and anthozoans (Anthozoa: Hexacorallia) in epipelagic waters based on in situ records

Journal of Fish Biology, Volume 107, Issue 6, Page 2166-2172, December 2025.
Abstract We formally describe the association of fishes and anthozoans in epipelagic waters, extending this relationship to beyond the benthos. In situ observations and photographs of Aluterus schoepfii, Ariomma regulus, Caranx cf. latus and Brama spp.

Nudibranch Suborders Classification based on Densely Connected Convolutional Networks

JITCE (Journal of Information Technology and Computer Engineering)
Nudibranchs, often called sea slugs, are a group of soft-bodied marine gastropod mollusks that shed their shells after their larval stage. With their body structure that is very similar between one suborder and another, sometimes it is hard to tell ...

Origin and Biogeography of the Colourful Sap‐Sucking Sea Slugs Genus Thuridilla Bergh, 1872 (Mollusca, Gastropoda, Heterobranchia)

Journal of Biogeography, Volume 52, Issue 10, October 2025.
ABSTRACT Aim Thuridilla Bergh, 1872, is a lineage of herbivorous sea slugs externally distinguished by bright colours and distinctive patterns of lines and spots. Recent work revealed an exceptionally rapid, cryptic radiation of 13 species in the Indo‐Pacific, raising questions about mechanisms of speciation in this group.

Natural Habitat and Wild Behaviors of the Dwarf Cuttlefish, Ascarosepion bandense

Ecology and Evolution, Volume 15, Issue 9, September 2025.
Gibbons et al. performed a field study to characterize the dwarf cuttlefish—a popular aquarium and research cephalopod—in its natural habitat. They observed dynamic camouflage, social behaviors, and use of an expanded color palette in wild animals compared to laboratory animals.
