Coho salmon die, chum salmon survive in stormwater runoff research
Scientists found that coho salmon became sick and nearly died, within just a few hours of exposure to polluted stormwater. But chum salmon showed no signs of ill-effects after prolonged exposure to the same water.

New new genus and species of extinct baleen whale identified
Paleontologists are rewriting the history of New Zealand's ancient whales by describing a previously unknown genus of baleen whale, alive more than 27.5 million years ago and found in the Hakataramea Valley, South Canterbury.

Marine fish won an evolutionary lottery 66 million years ago
Why do the Earth's oceans contain such a staggering diversity of fish of so many different sizes, shapes, colors and ecologies? The answer, biologists report, dates back 66 million years ago, when a six-mile-wide asteroid crashed to Earth, wiping out the dinosaurs and approximately 75 percent of animal and plant species worldwide.

More than 12,000 marine creatures uncovered during West Java deep-sea exploration
Scientists who participated in the South Java Deep Sea Biodiversity Expedition 2018 had collected more than 12,000 creatures during their 14-day voyage to survey the unexplored deep seas off the southern coast of West Java, Indonesia.

Giant group of octopus moms discovered in the deep sea
At the bottom of the ocean, scientists discovered hundreds of small pink octopuses and their eggs. The colonies were in warmer water than is healthy for octopuses, which means that they probably won't survive. That makes the scientists think there are probably even bigger colonies thriving in the cool rock crevices nearby.

Genetic evidence that magnetic navigation guides loggerhead sea turtles
New research provides valuable insight into the navigation and nesting behaviors of loggerhead sea turtles that could inform future conservation efforts. Loggerhead sea turtles that nest on beaches with similar magnetic fields are genetically similar to one another, according to a new study.

Switchblade-like defensive system redraws family tree of stonefishes
A new study details for the first time evolution of a 'lachrymal saber' unique to stonefishes -- a group of rare and elaborately dangerous fishes inhabiting Indo-Pacific coastal waters. The new finding rewrites scientific understanding of relationships among several groups of fishes and reveals a previously unknown defensive strategy -- also, it likely will fuel a few nightmares.

Repeat spawning comes with tradeoffs for trout
Steelhead trout that spawn multiple times have more than twice the lifetime reproductive success of single spawning trout, suggesting there is a substantial benefit associated with repeat spawning. But it comes with a tradeoff.

Nature-based solutions can prevent $50 billion in Gulf Coast flood damages
While coastal development and climate change are increasing the risk of flooding for communities along the US Gulf Coast, restoration of marshes and oyster reefs are among the most cost-effective solutions for reducing those risks, according to a new study.

Deeper understanding of species roles in ecosystems
A species' traits define the role it plays in the ecosystem in which it lives -- this is the conclusion of a new study. New methods can make it easier to predict the ecological role that a species will play when it is introduced, by accident or design, into a new habitat.

Extensive seagrass meadows discovered in Indian Ocean through satellite tracking of green turtles
Biologists have discovered for the first time extensive deep-water seagrass meadows in the middle of the vast Indian Ocean through satellite tracking the movement of green sea turtles.

Hotter, longer, more frequent -- marine heatwaves on the rise
We know heatwaves over land have been increasing, but now new research reveals globally marine heatwaves have also been increasing in length, number and intensity over the past century. More intriguing still, this trend has accelerated markedly since 1982.

Coral bleaching threatens the diversity of reef fish
New research reveals that global warming also affects fish who depend on corals. The Great Barrier Reef is revered for its kaleidoscope of color. New international research reveals that coral bleaching events not only whitewash corals, but can also reduce the variety of fish occupying these highly valued ecosystems.

Can we imitate organisms' abilities to decode water patterns for new technologies?
The shape of water. Can it tell us about what drives romance? Among fish, it might. Scientists are now studying how aquatic signals are transported through the water.
