Elasmobranch ectoparasite communities in Miami, FL

Parasite communities and interactions with their hosts can provide insight into how host species live. Host life history, species, habitat, size, age, and population health can have effects on parasite communities.

Progress of Elasmobranch in China

, 2006
我国对板鳃鱼类的研究比较薄弱.本文从演化和分类学地位、生物学研究、物种多样性和生化组分研究以及生物活性物质研究方面介绍了我国板鳃鱼类的研究进展,并对我国板鳃鱼类研究的发展方向提出几点建议.Elasmobranch study is weak comparatively in China.In this paper,a summary of present Elasmobranch study in China is made,which includes all the sides,such as ...

NEAFC request - Northeast Atlantic elasmobranch species classification

, 2011
A table classifying elasmobranch species found within the NEAFC area is provided. Advice on basking shark, Cetorhinus maximus, and porbeagle, Lamna nasus, has remained unchanged for some years and new advice will be provided in 2012.

Historical Records of Tumours in New Zealand Marine Fishes

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Tumours were first described in New Zealand marine fishes in 1982 but those early records have been difficult to access and subsequently few tumours have been collected and little has been published. This review updates records of identified tumours from teleosts in the New Zealand marine environment and may encourage more work to identify background ...

Novel evidence of interaction between killer whales (Orcinus orca) and juvenile white sharks (Carcharodon carcharias) in the Gulf of California, Mexico

Frontiers in Marine Science
White sharks (Carcharodon carcharias), have only one known natural predator in the ocean, the orca or killer whale (Orcinus orca). While interactions between these coexisting apex predators are known to occur, killer whales are adept at subduing adult ...

Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

Fisheries Management and Ecology, Volume 33, Issue 3, Page 463-478, June 2026.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Cities at Sea: Coastal Urbanization Generates Local Biodiversity Hotspots but Homogenizes Marine Fish Communities Regionally

Global Change Biology, Volume 32, Issue 6, June 2026.
We investigated whether coastal urbanization drives marine communities toward greater similarity, a process well‐documented as urban biotic homogenization in terrestrial and freshwater ecosystems but largely unexplored in the marine realm. From seawater environmental DNA samples collected along the French Mediterranean coastline targeting fish ...

Evolutionary Stability of the Shark Snout: Geometric Morphometrics of Ventral Facial Openings

Annals of the New York Academy of Sciences, Volume 1560, Issue 1, June 2026.
Landmark‐based geometric morphometrics of 453 shark species reveal that ventral head morphology is conserved across Selachii. Morphospace and ancestral reconstructions support strong phylogenetic control and limited divergence from ancestral conditions.
