TL;DR: It is demonstrated that the nursery region of white sharks includes waters of southern California, USA, and Baja Cali- fornia, Mexico, and juvenile white sharks captured as bycatch in both US and Mexican waters, suggesting that management of fishing mortality should be of increased concern.

TL;DR: Manta and devil rays of the subfamily Mobulinae (mobulids) are rarely studied, large, pelagic elasmobranchs, with all eight of well-evaluated species listed on the IUCN Red List as threatened or near threatened.

TL;DR: Differences in organic contaminant signatures and contaminant concentration magnitudes among species corroborated what is known about species habitat use and may be used to provide insights into the feeding ecology of these animals.

TL;DR: Maternal offloading of organic contaminants during reproduction has been noted in other apex predators, but this is the first evidence of transfer in a matrotrophic shark.

TL;DR: The closely shared evolutionary history of mobulids in combination with ongoing threats from fisheries and climate change effects on upwelling and food supply, reinforces the case for greater protection of this charismatic family of pelagic filter feeders.
