Nudibranch Cadlina rumia discriminates waterborne cues to find prey and conspecifics and avoid threats.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The dorid nudibranch Cadlina rumia is a tropical western Atlantic species commonly found under boulders and that frequently preys upon the chemically defended sponge Dysidea etheria. We evaluated the ability of C. rumia to recognize waterborne chemical cues from its prey, predator, and conspecifics. Y-maze experiments with two-current choice (control - seawater and treatment - conditioned seawater) flumes were carried out using different conditioned seawater samples soaked with cues for either 1h or 6h, obtained from (1) fresh D. etheria, (2) D. etheria actively consumed, (3) D. etheria artificially damaged (simulated predation), (4) conspecific nudibranchs and (5) its potential predator, the crab Pachygrapsus transversus. Specimens of C. rumia discerned the different chemicals offered to them after a short period of bioassays (within 10 min), regardless of the soaking time. C. rumia exhibited positive attraction to chemical cues from all D. etheria prey treatments and from conspecifics, whereas negative attraction was observed in response to the chemical cues from the crab P. transversus. Our results revealed graded differences in the strength of behavioral responses to different chemical cues, with fresh sponge-conditioned seawater eliciting the strongest attraction, followed by actively consumed sponge and conspecific cues, and a less pronounced response to artificially damaged sponge. Thus, C. rumia not only recognized the chemical cues but also showed differential sensitivity to them, possibly enhancing its ability to detect and capture prey, locate mates, and avoid predators, key selective pressures shaping survival and reproductive success in its environment.
