Young Caribbean manta rays (Mobula yarae) often travel with small groups of other fish near the coast of South Florida. Palm Beach County is a known nursery where juvenile mantas are common.
A team from the Marine Megafauna Foundation and the University of Miami studied video recorded between 2016 and 2021 to learn which species use the mantas and where they gather on the animals. The most common companions were remoras and fish important to local fisheries, such as jacks and cobia. Fish often gathered near the mantas’ gills, eyes, wings and tail.
Because the area is busy with boats and fishing, researchers recommend slowing down where mantas feed and using careful boating and fishing practices to reduce harm.

Emotion helps the brain form lasting memories
Researchers used fMRI brain scans while people watched movie clips and listened to stories. They found that strong emotional moments make brain regions work together more, and this stronger integration predicts better memory for those moments.
