Effects of human modification to freshwater flow on juvenile bull shark movement and residency in a subtropical nursery

Kristine Zikmanis, Patrick O’Donnell, Simon Dedman, Michael R. Heithaus

ABSTRACT (part)
Understanding how organisms will respond to variation in environmental conditions is critical to predicting how species and ecosystems will respond to human impacts, including restoration efforts. We used boosted regression tree analysis to investigate the factors influencing bull shark C. leucas residency and movement within a coastal nursery (Ten Thousand Islands, Florida, USA) that experiences considerable spatiotemporal variation in freshwater inputs and other conditions due to human development of its watersheds. We used passive acoustic tracking to quantify juvenile bull shark habitat use relative to variation in abiotic and biotic factors across scales of days to seasons. Sharks exhibited considerable inter-individual variation in residency, with 4 distinct patterns observed, including long-term resident and transient tactics. Salinity was a key driver of both overall residency of sharks and their use of specific areas within the region. Within our study area, sharks used an artificially freshwater-enhanced bay far more frequently than a freshwater-deprived bay year-round. With seasonal increases in salinities, most sharks moved further upstream into a man-made canal and then moved back downstream into the freshwater-enhanced bay as salinities dropped. Based on our results, any potential increases in salinity from the completion of an ongoing restoration project upstream could shift bull shark residency, potentially increasing reliance on the man-made canal (...)

Begat, A. & Kriwet, J. & Gelfo, J.N. & Gouiric-Cavalli, S. & Schultz, J.A. & Martin, T. (2025): Novel perspectives on Late Cretaceous elasmobranch diversity in the Southern Hemisphere high latitudes. Paläontologische Zeitschrift, in press
New species: Scapanorhynchus patagonensis
Abstract: Two new vertebrate assemblages rich in elasmobranch isolated teeth and dermal denticles from the lower Cenomanian (Upper Cretaceous) of Patagonia in southern Argentina comprise ten identified taxa (†Protosqualus sp., †Heterodontus sp., †Orectoloboides sp., †Carcharias sp., †Scapanorhynchus patagonensis sp. nov., †Squalicorax sp., †Paraorthacodus sp., †Rhinobatos aff. †R. incertus, †Ptychotrygon ameghinorum, †Ptychotrygon sp.) and five unidentified lamniforms. The material comes from two closely positioned sites representing proximal palaeoenvironments (delta and lagoonal foot barrier, respectively). The new elasmobranch sites are the most diverse known from the Upper Cretaceous of Patagonia until today and indicate a remarkable elasmobranch diversity in high latitudes of the Southern Hemisphere. They are dominated by warm-water taxa demonstrating a strong Tethyan influence into the southern part of the Austral Basin, contrasting with the later Weddellian influence as indicated by the presence of cold-water taxa in that area during the Campanian and the Maastrichtian.

Otero, R.A. & Soto-Acuña, S. & Ugalde, R. & Sepúlveda, P. & Vargas, A.O. & Aguirrezabala, G. & Ortiz, H. (2026): A new Upper Cretaceous bramble shark from central Chile reveals austral diversity among Weddellian echinorhinids. Cretaceous Research, in press
New species: Echinorhinus taverai
Abstract: Teeth of bramble sharks (Echinorhinidae) are one of the scarcest chondrichthyan elements reported to date in the Upper Cretaceous of central Chile and in general, South America. Prior to this research, its local record was restricted to only four available specimens, previously considered to be equivalent to teeth from the upper Maastrichtian of Argentinean Patagonia, being these referred to the species Echinorhinus maremagnum. This contribution presents two new elements, including the first complete large tooth from central Chile, showing the presence of a distally projected basal cusplet and a complex mesial, serrated cutting edge with the primordium of two clear cusplets, this last being a trait commonly present in several Cenozoic species. These new features remained unnoticed in the previous material from central Chile, either due to informative portions missing or the immature growth stage of the smaller known sample. The dental features of the new specimen are unique among known species of the genus Echinorhinus; moreover, the crown traits represent an ancestral condition with respect to those features commonly present in Cenozoic species. With the new evidence, all the known Echinorhinus teeth from the lower Maastrichtian of central Chile are now referred to Echinorhinus taverai sp. nov. The occurrence of the studied material directly associated with an elasmosaur skeleton is consistent with other findings of the genus in the Southern Hemisphere, suggesting that Upper Cretaceous austral Echinorhinus spp. were opportunistic scavengers in the shallow coastal waters of southern South America.

Vullo, R. & Fragoso, L.G.C. & Bittencourt, J.S. & Pérez-García, A. & Bouchemla, I. & Benyoucef, M. (2026): A new genus of lonchidiid hybodontiform sharks from the Cretaceous of North Africa and South America. Geological Magazine, 163, Article e6
New genus: Lonchidionoides
New species: Lonchidionoides trifurcatum
Abstract: Minute hybodont shark teeth from uppermost Albian–lower Cenomanian (mid-Cretaceous) continental deposits of Djebel Amour (Saharan Atlas, Algeria) are described. They are assigned to a new genus and species of Lonchidiidae, Lonchidionoides trifurcatum. Similar teeth recently reported from the Early Cretaceous of Brazil are here referred to as Lonchidionoides sp. The heterodont dentition of Lonchidionoides is characterized by clutching anterior teeth with a tricuspid crown and larger crushing posterior teeth with less individualized cusps. Lateral teeth show an intermediate morphology. The two occurrences of this non-marine hybodontiform genus may reflect the existence of a large ancestral distribution area that was divided during the opening of the South Atlantic, as previously suggested for several groups of cartilaginous and bony fishes.

Longstaff, K. & Bruce, N.L. & Smit, N.J. & Hadfield, K.A. (2025): Three new species of Argathona (Isopoda: Corallanidae) from Indonesian and Malaysian Borneo, with the first records from elasmobranch hosts. International Journal For Parasitology-Parasites and Wildlife, 28, Article 101157
New species: Argathona magnocula, Argathona terputa, Argathona lebara
Abstract: Although Borneo lies within the highly biodiverse Coral Triangle, its reported isopod diversity remains poorly documented and underexplored. This study documents four species of the corallanid isopod genus Argathona collected from elasmobranch hosts in Indonesian and Malaysian Borneo, namely A. lineata, A. magnocula sp. nov., A. lebara sp. nov., and A. terputa sp. nov. Specimens were identified based on detailed morphological characters. Argathona magnocula sp. nov. is characterised by a posteriorly elongate frontal lamina that is three times longer than its posterior width; eyes separated by ∼34 % of head width; a pleotelson with a sub-truncate posterior margin and dorsal fields of hyaline setae; and uropodal rami barely extending beyond the pleotelson. Argathona lebara sp. nov. is distinguished by its short, broad frontal lamina (shorter than wide), small eyes, deeply concave maxillula mesial lobe, and exceptionally long antennae reaching pereonite 7. Argathona terputa sp. nov. features a broadly truncate pleotelson, short antennula (extending only to the eye's posterior), and uropodal rami that do not extend past the pleotelson apex. It can be separated from A. lineata by its broader pleotelson margin, shorter frontal lamina, reduced setation, and the presence of two simple setae on the maxillula mesial lobe. This study describes three new species, reveals novel host associations with four elasmobranch species, and transfers Alcirona grandis into the genus.

Kelidsar, H.H. & Haseli, M. (2025): Echinocephalus persicus n. sp. (Nematoda: Spirurida: Gnathostomatidae) from Two Batoid Hosts, Pastinachus sephen and Urogymnus asperrimus, off Southern Iran. International Journal For Parasitology-Parasites and Wildlife, 29, Article 101173
New species: Echinocephalus persicus
Abstract: Adult nematodes of the genus Echinocephalus were recovered from the intestines of two batoid species—Pastinachus sephen, collected from both the Persian Gulf and the Gulf of Oman, and Urogymnus asperrimus, collected from the Persian Gulf. Detailed morphological analyses were conducted using light and scanning electron microscopy. Based on the number, arrangement, and size of caudal papillae, along with other morphological and quantitative traits, the specimens were clearly distinguishable from previously described congeners. Consequently, Echinocephalus persicus n. sp. is formally described and added to the genus. With this addition, the total number of valid Echinocephalus species rises to 13, four of which are known from the Indian Ocean, restricted to the coastal waters of India, Sri Lanka, and Iran. Notably, Urogymnus asperrimus hosts four of the four known Echinocephalus species from the Indian Ocean—including three from Sri Lankan waters and one from southern Iran—suggesting that this batoid may represent a species complex and thus warrants further taxonomic reassessment. In addition, the external anatomy of the amphid was discussed across the genus. Observations of fixed specimens of E. persicus n. sp. indicate that intraindividual comparisons of cervical sac length should be made with caution due to potential variability among the four sacs.

Walking sharks break the rules of reproduction

Summary: Epaulette sharks can reproduce without any measurable increase in energy use, stunning researchers who expected egg-laying to be costly. Scientists tracked metabolism, blood, and hormone levels through the entire reproductive cycle and found everything stayed remarkably stable. This efficiency suggests these sharks have evolved to optimize energy in ways not seen before.
