Deep sea animals face greater risks compared to those nearer the surface as they become less able to maintain their preferred thermal habitats with climate change.

Through a series of prosocial choice tasks, researchers reveal prosocial and antisocial characteristics in male convict cichlid fish. The fish distinguish between female breeding partners, unknown females, and rival males by adjusting their actions to either provide food for both them and the females or avoid providing food for the rival males.

Recognizing species is important for understanding regional biodiversity and for environmental conservation. However, taxonomic identity is sometimes obscure even with the organisms that are closest to human life.

Scientist's understanding of this microscopic invertebrate has grown after the second discovery of Loricifera near Japan.

Scientists could gain insight into atypical sex development in vertebrates, including humans, by studying how nutrition affects sex changes in fish larvae.

During the early summer, corals simultaneously release tiny balls composed of sperm and eggs, known as bundles, that float to the ocean surface. Here the bundles open, allowing the sperm to fertilize the eggs where they eventually settle on the seafloor and become new coral on the reef.

Global simulations suggest plankton and fish species are showing resilience to climate change by going deeper underwater or moving to higher latitudes.

A new beaked whale species Berardius minimus, which has been long postulated by local whalers in Hokkaido, Japan, has been confirmed.

A group of biologists from Hong Kong Baptist University (HKBU) have discovered a new fireworm species in Hong Kong waters and named it Chloeia bimaculata. It is the fourth named species to be added to the fireworm genus Chloeia during the last century. The team also identified Chloeia parva as the fireworm species that caused the outbreak in Hong Kong last year. The discovery shows how little people know about the biodiversity of this group of animals.

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has analyzed the genetic map of Nomura’s jellyfish, scientifically known as Nemopilema nomurai, for the first time.

Malaysia seeks alternative solutions to prevent and treat infectious diseases in shrimp.

Direct electrolysis has mixed results for extracting fuel sources from microalgae.

Biologists in Japan have identified four distinct zones in the otolith, a calcium carbonate structure in the inner ear, which can be used to determine age in fish.

Investigating plankton communities' reaction to rising water temperatures may improve modeling of marine ecosystem responses to global warming.

Investigations of prey patterns fail to explain why whale sharks aggregate off the coast of Saudi Arabia.

The techniques that make industrial pearl culturing possible were developed over a century ago at the Misaki Marine Biological Station in Japan.

A molecular process that signals distress could also help corals adapt to climate change.

A international team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has carried out a scientific investigation on dolphin liberation in South Korea.

Big data shows that large marine vertebrates move differently, but consistently, through coastal and ocean waters.

Color changes in the northern Red Sea indicate rising sea temperatures could significantly impact tropical marine ecosystems.

An electronic tag that stretches and flexes while it records location and environmental data can monitor marine animals in their natural habitat.

In the longest running study of its kind, researchers found sea urchin populations were strongly affected by human-driven environmental changes.

Researchers show how a fish species in Lake Tanganyika works together to secure additional food sources.

HKUST Researchers Identify Irreversible Adverse Effects of Microbeads on Marine Animals’ Growth and Development

Researchers led by Nagoya University discover penetrative trace fossils from the late Ediacaran of western Mongolia, revealing earlier onset of the “agronomic revolution”.

A comparison of the genomes of two species of coral demonstrates unexpected genetic diversity.

Jumping genes could make an alga, and its coral host, more tolerant to warming sea temperatures.

Some species of fish have special adaptive mechanisms that could improve their chances of surviving the greenhouse effect.

Turbulence and nutrient availability drive changes in Red Sea microbes.

The world’s warmest sea is heating up faster than the global average, which could challenge the ability of the Red Sea’s organisms to cope.
