Dying Coral Reefs Found Around Samoan Island of Upolu

Find out why coral reefs around a remote Samoan Island are dying and why it was not what scientists were expecting. 

This Wiggly Robotic Fish Could Advance Marine Research

See how this advanced robotic "fish" can help marine biologists monitor the health of habitats by blending in.

Electric Octopus

An octopus uses camouflage as its first line of defence against predators—a mesmerising sight.

Climate Change Is Suffocating Large Parts of the Ocean

Find out why low oxygen zones in the ocean are growing in size and the effect it is having on marine life.

Largest Coral Sperm Bank May Save Our Reefs

The Taronga Conservation Society operates the largest coral sperm bank in the world. During the recent coral spawning season, scientists were able to collect 171 billion sperm from 31 coral colonies, which were later frozen and preserved. The hope is to use the frozen sperm to help rebuild coral reefs as they face die-offs due to warming waters and habitat destruction.

Watch Baby Sea Turtles Run on Treadmills—for Science 

How miniature treadmills and tiny swimsuits have helped scientists study baby turtles

See Secret Eating Habits of Deep-Sea Creatures

The ocean depths hold a complex network of predators and prey. Some links in that network, once unknown, have now come into view. When preyed upon, gelatinous animals, like jellyfish and comb jellies, quickly become unrecognisable, and so are undercounted in predators’ guts. Plus, jellies are hard to catch with a net. But with remote-operated vehicles, Monterey Bay Aquarium Research Institute (MBARI) researchers have been filming ocean life — including jellies — for decades. By reviewing their footage, MBARI has changed the model of the deep-sea ecosystem. They've found that jelly-like animals play a bigger role than previously thought. Jellies served as a food source for several types of sea creatures, and also preyed upon a number of species, such as squid. The food web just got a little more tangled.
