We present the first confirmed report on the presence of spinner shark, Carcharhinus brevipinna, in Maldivian waters. The species was observed in front of Kooddoo’s harbour, in Villingili pass, Northern Huvadhoo Atoll, Southern Maldives in March 2020.

The great white shark, Carcharodon carcharias (Linnaeus, 1758), is a well-known predatory species that inhabits a wide geographic range, including the Adriatic Sea. A marked decline in the abundance of its Mediterranean population has been documented over recent decades, making research on this species in its natural environment increasingly difficult. This study documents two contemporary records of young-of-the-year individuals recorded in 2018 and 2025 off the coasts of Croatia and Montenegro, respectively. Both records were sourced from local fisheries and were subsequently reported to scientists through citizen science. The individual reported from Montenegro was photographed and released unharmed while still in the water. This study further highlights the importance of citizen science in documenting occurrences of elusive elasmobranchs such as the great white shark and in educating fishers through a bottom-up approach. Together with the recently recorded young-of-the-year specimen in this area, these observations suggest that the Eastern Adriatic Sea may represent a contemporary nursery area for the great white shark, although this hypothesis remains to be verified.

Interactions between large pelagic sharks and marine aquaculture remain poorly documented in the Mediterranean Sea. We report six cage-entry events involving blue sharks, Prionace glauca (Linnaeus, 1758), and shortfin makos, Isurus oxyrinchus Rafinesque, 1810, associated with capture-based Atlantic bluefin tuna aquaculture and Atlantic salmon farming between 2018 and 2026. Records were compiled from direct observations, information provided by personnel involved in fishing and aquaculture operations, and original photographic and video material. Four cage-entry events occurred through breaches in the cage netting, while two blue sharks were captured incidentally with tuna in purse seines and subsequently transferred into transport cages. Three sharks were released alive and three died after becoming entangled in cage netting. Evidence of feeding was recorded in five of the six cage-entry events. The records demonstrate two distinct pathways of shark entry into aquaculture cages: entry through breaches in cage netting and incidental transfer from purse seines into tuna transport cages. Although the opportunistic nature of the observations precludes estimation of interaction frequency, the documented mortalities highlight the importance of systematic reporting, rapid-release procedures, and mitigation measures aimed at reducing shark entry and entanglement.
