Two SCUBA divers, one holding a large black grouper, the other quickly implants an acoustic transmitter. The divers are out of focus. In the foreground some small damselfish flitter about and a sea whip waves gently in the current.
A stingray laying on a sandy ocean bottom with small rocks to the right and soft corals (sea fans) to the left.
A brown fish with yellow fin edges laying on a white cooler.
A bright white fish with yellow stripes and yellow fins and two bold black bars on the front end.
A fish in a hand.
Underwater image of a large greenish yellow fish in the foreground. A SCUBA diver swims above and behind the fish. In the distance on the right side is an acoustic telemetry hydrophone reciever mounted to a steel cable with round buoys at the top and steel plates anchoring it to the bottom.
Brown colored fish face looking out of a hole in the ocean bottom covered in various types of brown and green algae and small corals.
Digital image of a large fish (a red grouper) in a hole on the ocean floor. There are smaller fish of multiple species in and around the top of the hole, along with lobsters of various sizes. Arrows originating from the red grouper go towards the different species, indicating the direction of ecological interactions. Dotted lines with positive (+) signs represent positive indirect interactions between the red grouper and a small school of reef fishes, between the red grouper and large lobsters, and between the red grouper and cleaner shrimp living on an anemone. A solid arrow with a negative (-) sign represents a negative direct interaction between the red grouper and a small lobster.

Cover page of a scientific article showing title, author, DOI info, part of abstract and graphical abstract, which is an image of fish and lobsters in a hole with arrows showing interactions between different species.

Facetious plot of the inverse correlation between Global Average Temperature on the y-axis and the Number of Pirates currently terrorizing the high seas.
Two male researchers are seated on a boat deck with a large fish in front of them. One scientist is holding a hose that is flowing water over the fish's gills, while the other is holding a suture needle and is closing a small incision on the fish's belly.
