Ethology, Volume 132, Issue 3, Page 225-234, March 2026.We documented a novel predator–predator commensal foraging interaction between cobia (Rachycentron canadum) and a southern stingray (Hypanus americanus) in a shallow coastal habitat of Biscayne Bay, Florida. Using drone‐based observations, we recorded a 7‐min sequence in which a cobia closely tracked the stingray's movements and fed on prey disturbed ...

Bioturbation by stingrays at Ningaloo Reef, Western Australia [PDF]
, 2012 Stingrays are an important part of the biomass of the fishes in shallow coastal ecosystems, particularly in inter-reefal areas. In these habitats, they are considered keystone species -modifying physical and biological habitats through their foraging and

Marine Ecology, Volume 47, Issue 2, March/April 2026.ABSTRACT Rays are common marine mesopredators that use coastal and estuarine habitats during multiple life history stages for critical functions. They are long‐lived, late to mature, and have low reproductive output, making them vulnerable to and slow to recover from population threats such as overfishing and habitat loss.

Frontiers in Ecology and Evolution, 2018 Manta rays and their relatives of the family Myliobatidae have pectoral fins that have been modified for underwater flight, as well as a pair of fleshy projections at the anterior of the body called cephalic lobes, which are specialized for feeding. As a

The Overlooked Threat of Global Warming on Elasmobranch Fertility
Fish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.

Composition and conservation status of rays sold in Baja California Sur, Mexico
Conservation Science and Practice, Volume 7, Issue 12, December 2025.An analysis of the species composition of ray species sold under a general label in La Paz, Baja California, Sur Mexico. DNA barcode sequencing of the CO1 gene was utilized to assess ray filets, and species identification was compared to IUCN Red List to understand the vulnerability status of ray species being sold.

Natural antioxidants in the stability of ray liver oil
Ciência Rural: The effect of the addition of natural antioxidants on oxidative stability of ray ( Rhinoptera bonasus) liver oil was evaluated. Different concentrations of rosemary extract, α-tocopherol, and caffeic acid (w/w) were added to the oil.

Reproductive cycle, nutrition and growth of captive blue spotted stingray, Dasyatis kuhlii (Dasyatidae) [PDF]
, 2010 At Burgers' Ocean 7 male and 3 female blue spotted stingrays, Dasyatis kuhlii were born over a period of 4.5 years. This paper describes the experiences of the captive breeding results of this species. The first two young died within 2 days of birth. One

Fish Predation in Bivalve Aquaculture: Impacts and Potential Mitigation Strategies
Reviews in Aquaculture, Volume 17, Issue 3, June 2025.ABSTRACT Fish predation poses a significant challenge to bivalve aquaculture throughout the global range of production. However, the issue remains poorly understood, preventing the advance of effective interventions. Fish predation, especially on mussels in longline culture, can be severe and, in some instances, lead to crop losses of up to 100%, which
