🎨 Think reef fish colors are fixed? Think again.
Adult sunrise dottybacks (P. flavivertex) can change color and pattern over time, with different morphs converging toward similar appearances. #CoralReefs #ReefFish #KAUST

Proof that you don’t have to live by the ocean to be inspired to study it.

A fun fact: Dr. Majoris grew up in western Pennsylvania—far from the ocean! 🌾
After a summer at Penn State’s Governor’s School, he set up a saltwater aquarium in his basement. When the fish began breeding, it sparked a lifelong fascination with marine life. 🐠💙

🐠 Meet Dr. John Majoris, one of the newest faculty members in Penn State Biology!
His lab studies the “real-life Finding Nemo” — how tiny reef fish larvae navigate the open ocean to find a reef to call home. 🌊👇🧵

Blennies may provide key food web links between detritus, inverts, & algae they consume & bigger fish that eat them! I had a great time sharing my work on what stable isotopes & DNA metabarcoding can reveal about their trophic roles at the Texas Bays & Estuaries Mtg!
