Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Community science datasets identify the spatial occurrence and hotspots of flapper skate (Dipturus intermedius)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The flapper skate, Dipturus intermedius (Parnell, 1837), is a large‐bodied, slow‐growing and late‐maturing, Critically Endangered elasmobranch with a constrained population distribution. Here, we use two longitudinal community science datasets to investigate the occurrence of flapper skates in Irish waters. The two datasets are as follows: the
