ALT A Mediterranean monk seal swimming just below the ocean surface in clear blue water, facing toward the camera with its fore flippers extended behind. The seal has a robust, streamlined body with grey coloration, a rounded head, prominent whiskers, and large dark eyes. The surrounding open water contains no other animals or prominent features, emphasizing the seal in its natural marine environment.
ALT Researchers conduct photo-identification of a juvenile green turtle (Chelonia mydas) in Rapa Nui, Chile, by photographing the left side of its head, capturing its unique facial scale pattern. A field data board displaying the turtle's identification and sampling information is positioned beside the animal.
ALT Mongolian fish biologist, Ganzorig Batsaikhan, holds a large taimen. There are a river and trees in the background.
ALT An aerial drone photograph shows the waters of Laucala Bay with Suva city in the background. In the lower central portion of the image, a single oceanic manta ray is visible feeding at the surface, with its pale ventral surface breaking the water's surface. In the background, the coastline stretches horizontally across the upper third of the image, showing a developed urban area with various buildings, infrastructure, and dense vegetation, backed by rolling hills under a cloudy sky. This image visually demonstrates the close proximity of these endangered rays to a highly populated and heavily modified urban environment, highlighting their unexpected use of coastal habitats for foraging.
ALT Photograph of a male leopard shark closely pursuing a female alongside a reef in Mozambique. The image shows one of the courtship interactions described in the study.
ALT The picture shows a female adult pesut dolphin named ‘nenek’ (or grandmother) Fiona who is not only identified based on unique features of her dorsal fin but is known by local villagers and tourists because she has a hump just behind her neck giving the dolphin a massive appearance. Fiona has been identified since the photo-id study first started in 1999. In the background there is an approaching tugboat with 300 feet-large coal-barge. This large-sized coal barge traffic with draught between 4 to 6 m deep not only causes underwater pollution but also at least two known collision cases of a calf and juvenile pesut. Vessel collisions of coal barges and speedboats account for eight percent of known mortality causes.

ALT Three franciscana dolphins swimming.
ALT Researcher (Dr Nakia Cullain) looks down at a reef manta ray in shallow coastal water before attaching an acoustic transmitter. The image captures fieldwork used to monitor manta ray movements between Mozambique and South Africa, helping identify important habitats and inform cross-border conservation of this vulnerable species.
ALT A European mink Mustela lutreola.
ALT Photograph of the rare moss Buxbaumia viridis growing on decaying wood in a forest habitat, showing its distinctive elongated sporophytes emerging from reduced gametophytes. An inset map of Slovenia displays the current predicted habitat suitability for the species, with warmer-to-greener colors indicating increasing suitability, alongside occurrence records from the 19th, 20th, and 21st centuries marked with different colored points.
ALT A still image taken from a baited remote underwater video station (BRUVS) on which an angelshark Squatina squatina was sighted in the IUCN Cardigan-Caernarfon Bay Important Shark and Ray Area in Wales, United Kingdom. The image is very clear, there are no obvious claspers showing that the shark sighted is female. The BRUVS is deployed on a sandy seabed and there is a spider crab attached to the bait box, visible in the foreground whilst the angelshark is clearly visible in the background.
ALT Two basking sharks swim side by side near the ocean surface, their dorsal fins and broad backs breaking through calm blue water as they glide in close formation.
ALT Juvenile green sea turtle being gently held by a researcher above clear blue ocean waters under a cloudy sky, illustrating marine fieldwork and conservation research in São Tomé.
ALT The back of a Cook Inlet beluga whale is visible in the Kenai River. On the other side of the river is a commercial fishing boat, with a towering, snow-capped mountain in the background.
ALT A Japanese eel Anguilla japonica rests on a gravel riverbed underwater, showing a dark gray back and pale underside. Its head is slightly raised with the mouth partly open and one round eye visible, set against a softly lit natural benthic habitat with scattered stones.
ALT A diver wearing snorkeling gear is shown in the water holding a newly captured loggerhead turtle.
ALT Female beluga with calf.
ALT This photo is of a ringed seal amidst ocean water and sea ice floes, looking at the photographer. The seal has dark gray pelage mottled with lighter gray spots and rings. The photo was taken by Anna Bryan from the Alaska Department of Fish and Game during research conducted under a federal research permit.
