The Yellowtail tang, Zebrasoma xanthurum, uses its sharp scalpel-like tail spine for defense—hence its nickname "surgeonfish." An unsuspecting predator may find itself sliced by this hidden blade.

Brain corals, named for their convoluted, brain-like appearance, are living animals that build entire reefs by secreting calcium carbonate. These corals are actually colonies of polyps working together as a single organism.

The blue koran angelfish has a remarkable transformation. Youngsters sport electric blue, zebra-like stripes that fade into a more muted palette as they mature, a natural camouflage tactic in the wild.

China rockfish are among the longest-living fish species, with some reaching over 79 years of age. Their slow growth and longevity make them particularly vulnerable to overfishing.

The giant green anemone turns itself bright green by hosting symbiotic algae in its tissues, which photosynthesize and help the anemone feed by sharing energy from sunlight.

The strawberry false coral (Corynactis californica) isn't a coral at all but an anemone. Unlike true corals, they don't build reefs and thrive independently in the cool waters of the Pacific.

Note on Emerging Science: Sea 'Lavender' Stores Carbon
Sea lavender is both beautiful and powerful; its ability to store large amounts of carbon helps to mitigate atmospheric warming. (Photo: Stan Shebs, Wikimedia Commons, CC BY-SA 3.0) Sea ‘lavender,’ a purple flowering plant also known as statice that grows abundantly in salt marshes and coasts around the world, appears to be excellent at removing planet-warming carbon from the atmosphere and storing it in soils. Living on Earth’s Julia Vaz reports on this recent research. Transcript DOERING: In a moment, encountering wonder in the desert, but first this note on emerging science from Living on Earth’s Julia Vaz. [SCIENCE NOTE THEME] VAZ: East or West, the United States seaside is dotted with purple. The plant Sea Lavender grows abundantly in salt marshes. Which makes for a beautiful picture: mixing with the blue of the sea, soft green grass, and golden dunes. Beyond striking, sea lavender is also a powerful fighter against climate change. Researchers in Venice, Italy, where sea lavender also grows, recently found that the plant is excellent at storing carbon. The researchers from the University of Padova spent the summers of 2021 and 2023 knee-deep in salt marshes in Venice collecting data on different plots of vegetation. They...
