Marine heatwaves decimate sea urchins, mollusks and more at Rottnest
Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as mollusks and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 percent bet.....»»
Researchers reveal true crabs" epic ancient odyssey from sea to land and back again
Crabs are unique and continuously evolving animals, often moving their lifestyles out of marine environments for other environments to do so. The most popular food species can be fully marine (snow crab) or estuarine (Maryland blue crab, Dungeness cr.....»»
Can we eat our way through an exploding sea urchin problem?
Longspined sea urchins are native to temperate waters around New South Wales. But as oceans heat up, their range has expanded more than 650km, through eastern Victoria and south to Tasmania. Their numbers are exploding in the process, clear-felling k.....»»

On the trail of the "Silver King": Researchers reveal unprecedented look at tarpon migration
New research led by the University of Massachusetts and published recently in Marine Biology unveils a first-of-its-kind dataset, gathered over five years, that gives the finest-grained detail into the timing and spatial extent of tarpon migration. T.....»»
A new type of ringed seal described in West Greenland
The Arctic marine ecosystem is undergoing substantial changes, currently warming at rates well above the global average and seeing an increase in anthropogenic activities. Yet, due to the unexplored "hidden" nature of the Arctic, uncertainties remain.....»»
Biases found in coral reef research
Coral reefs support approximately 25% of marine species, and are essential to coastal economies, such as the fishing and tourism industries, to name a few. But coral reefs worldwide are at risk due to climate change and are on the brink of collapse......»»
New research finds marine bacteria ditched their flagella and other traits when migrating back to the ocean
Scientists have discovered flagella in an unexpected place: hot spring-dwelling bacteria from the phylum Chloroflexota. Research shows that flagella were lost in other forms of Chloroflexota that adapted to marine environments hundreds of millions of.....»»
Why 10 billion snow crabs starved to death in the Bering Sea
A team of marine biologists with the U.S. National Oceanic and Atmospheric Administration's Alaska Fishery Science Center has solved the mystery of why approximately 10 billion snow crabs vanished from the Bering Sea back in 2018/2019—the water the.....»»

Waves of change: How sea-levels and climate altered the marine ecosystems at the South Pole 390–385 million years ago
During the Early-Middle Devonian period, a large landmass called Gondwana—which included parts of today's Africa, South America, and Antarctica—was located near the South Pole. Unlike today's icy conditions, the climate was warmer, and the sea le.....»»
Exploring the limits of marine burrow cohabitation
Good real estate is not easy to find, even for sea creatures. Sometimes, push comes to shove, and species resort to competition or conquering before weighing the benefits of sharing an ecosystem like housemates......»»
Reef-devouring predator survives coral bleaching and feasts on the survivors
Research conducted by marine biologists from the University of Sydney has found juvenile crown-of-thorns starfish can withstand tremendous heat waves well above levels that kill coral. These starfish then develop into carnivorous predators that devou.....»»
Marine mammal longevity study reveals remarkable advances in animal welfare
