Two California market squids ( Loligo opalescens ) mate in the waters off of California's Channel Islands. While spawning, the male's arms blush red as he embraces the female, a warning to other competing males to back-off. Find out how and why squids and other cephalopods change color .Read more

Human infants often already resemble their parents. Visitors coo, "Oh, she has your eyes," or "He is the spitting image of his father." But what if the infant (or in this case, the larva) looked entirely different from its adult parents, with different body shape and coloring? This is the case for many marine species, especially fishes, making it difficult to match up a larva with it's...Read more

Methane gas, trapped deep within the Earth's crust, can slowly leak from cracks in the seafloor known as methane seeps. While we would never consider methane as food, in the deep sea where there is little light or resources, microbes have evolved to turn methane into energy and live off of it . And where there are microbes, there are often other animals—such as tube worms or mussels—that eat...Read more

Coral reefs are some of the most endangered ecosystems on the planet that are home to beautiful wildlife and provide food to many people living on the coast. So how do you protect the reefs without cutting off communities from their food source? Instead of creating one big marine protected area to conserve coral reefs, one idea is to protect a series of smaller reef areas. A series of protected...Read more

Dead man’s fingers ( Alcyonium digitatum ) are soft corals named for their appendage-like appearance when thrown ashore by storms. The finger-like clumps of coral polyps come in various shades of pink, orange, white, grey, or yellow and are found along the northern Atlantic coasts of Europe and North America. View other images of Baltic Sea life in a photo gallery of Oceana’s 2011 expedition .Read more

In Ecuador’s Galapagos Islands, brown pelicans ( Pelecanus occidentalis ) nest at the top of a mangrove tree. Many other kinds of birds—as well as insects, frogs, snakes, and lizards—live in the canopy of mangroves. More about mangroves can be found in our Mangroves featured story .Read more

Over a 10-year period, NOAA scientists have collected 72,000 seawater samples, and their data show that the ocean is becoming more acidic because of climate change . That small change in acidity is enough to dissolve the shells of animals like this pteropod. In the lab, its shell dissolved in high-acidity seawater in 45 days. And in the wild, pteropod shells have already started dissolving in the...Read more

An Atlantic puffin ( Fratercula arctica ) carries many sandlances ( Ammodytidae ) in its mouth to take back to its hungry chick. Puffins have spiny tongues that, pressed against the roof of their mouths, help to hold ten or more fish at once without losing any along the way. The two parents of a single chick take turns bringing food back to the nest. It's possible to learn what kinds of fish are...Read more

Ultraviolet light illuminates the growth rings in a cross-section of a 44-year-old deep-sea coral ( Primnoa resedaeformis ) collected off the coast of Newfoundland at about 1,300 feet (400 meters). Similar to tree trunks, cross-sections reveal coral-growth rings that can be used to determine their age—and information about climate . Because coral growth depends on temperature, sunlight, and...Read more
