Sand tiger sharks are an iconic large shark species held in aquaria worldwide. They rarely reproduce under managed care, with only seven aquaria reporting limited and sporadic success. For the first time in the Americas, a full-term young was born in an aquarium. The young was the result of breeding among a group of sharks purposefully brought together in 2016 for reproduction. Sharks were maintained in natural seawater and exposed to natural light and seasonal temperature fluctuations similar to their in situ counterparts. Decreased food consumption associated with breeding season and gestation was observed. Gestation time estimated from breeding observations and parturition was 321 days. Although the neonate was stillborn, this was a significant achievement. The husbandry details described within will be useful for other aquaria striving to support the reproduction of sand tiger sharks.

A captive sand tiger shark () presented with progressive, hard, raised, miliary skin lesions localized to the lateral trunk and peduncle. Histopathologic evaluation of biopsy samples revealed dysplastic proliferation of odontogenic epithelium with the production of collagenous material. Inclusion bodies and viral particles were not observed with light or transmission electron microscopy, respectively.

Article Synopsis
- Human-wildlife conflicts in western Nepal, particularly involving elephants, leopards, and tigers, lead to human casualties and a negative perception of conservation efforts.
- A study analyzed 76 incidents of human deaths and injuries from 2019 to 2023, finding that tigers were responsible for 75% of attacks, predominantly occurring near forest edges during the day.
- To improve coexistence, strategies such as community patrols, habitat restoration, electric fencing, and insurance for local farmers were recommended to mitigate future conflicts.

Different blood group systems have been characterized in people and other mammals. In domestic cats, the blood group system plays the most important clinical role and has been investigated extensively-from the phenotype to the molecular genetics. In non-domestic felids, phenotypic blood typing has been performed by different methods to detect the antigens, but the four informative markers in domestic cats were not able to identify types and () in non-domestic cats.

This study investigated sand tiger shark (STS; Carcharias taurus) spatial use and exclusion in public aquarium enclosures using a novel protocol for three-dimensional mapping. Fifty-one STS were observed in 14 enclosures, and swimming pattern, depth, and location were recorded in ZooMonitor. Data were converted into quantitative, three-dimensional representations using ArcGIS® Pro v.

Non-invasive computed tomography (CT) of an adult sand tiger shark Rafinesque, 1810 is used to provide an interactive three-dimensional 'general' shark (Selachimorpha) anatomy atlas. Given its post-cranial body morphology, the sand tiger shark appeared to be a well-chosen candidate and through comparison of the sand tiger shark with several other representatives of all eight established orders of sharks, we confirm that the relatively large degree of mineralization of the endoskeleton, along with the overall size, makes the sand tiger shark an ideal candidate for skeletal segmentation and construction of a skeletal atlas using conventional CT. This atlas both increases accessibility to the internal morphological features of the sand tiger shark and provides a more generalized overview of the skeletal anatomy of sharks and can aid as a supplement to destructive fresh dissection of specimens in the future and the construction of future skeletal atlases of other less mineralized sharks.
