Scientists have broken the stereotype that winter is an off-season for lake plants, animals, and algae. Freshwater systems around the planet are incredibly active and much more complex, especially in recent times since climate change is warming lakes around the planet.
The lionfish is a species alien to the Mediterranean Sea, but an increase in sightings has signaled the start of a lionfish invasion. Climate change resulting in warmer water has opened the door to the lionfish threat.
Millions of tons of microplastics wind up in the world's oceans, threatening various marine life. A recent study, however, sheds light on how the tiny plastic particles are impacting Pacific oysters and their reproductive success.
Sea slugs have colorful patterns to ward off predators -- but when that doesn't work they defend themselves using toxic chemicals they gather from their environment.
Although the invasive species called Regal Damselfish may not make its way too far into the Gulf of Mexico, researchers say the Gulf's southern reefs can expect to see a lot more of these invasive fish relatively soon.
An extinct marine crustacean-like creature known as Dollocaris ingen was equipped with two large eyes, each about a quarter of its body size. Researchers say this likely gave the pipsqueak an advantage when ambushing its prey.
The noisy claw sounds of snapping shrimp may be a good indication of reef health, researchers say.
NASA recently launched a three-year expedition under its COral Reef Airborne Laboratory (CORAL) that will pair aerial surveys with underwater measurements to get a better idea of reef health.
Butterflyfish depend on food and shelter provided by coral reefs, but they steer clear of those that have come in contact with seaweed. Researchers suggest this may be a strong indicator of their awareness of reef health.
In the dark, cold waters of both the Antarctic and Arctic oceans, sea spiders are growing larger than usual. Researchers say this phenomenon, known as polar gigantism, may or may not be attributed to the abundance of oxygen in the seawater.
An innovative floating dam that traps plastic bags, bottles and other debris contaminating the world's oceans will be tested in the North Sea for the first time next year.
A dangerous fishing tactic used in Tanzania threatens local marine life. Despite laws prohibiting what's commonly known as blast fishing because explosives are involved, homemade bottle bombs are continually tossed into the sea, resulting in the deaths of hundreds of fish at a time and critical coral reefs.
Although fish biomass is often used to evaluate the effectiveness of conservation efforts, a new study suggests the metric doesn't provide the whole story. As a result, researchers are calling for the establihsment and maintenance of larger, more permanent "protected areas" for marine life to thrive.
Turbid or cloudy waters may help corals survive climate change by shading the iconic reefs from excess, damaging sun exposure.
Hawaiian bobtail squid harness luminescent bacteria in their predator-fooling light organs so that they can mimic moonlight and camouflage with the ocean's surface. This allows them to evade nighttime predators.
