A paper published Thursday in the journal Current Biology reports that a 27-million-year-old fossil from a species named Echovenator sandersi, nicknamed Echo Hunter, had features in its inner ear indicating that it could hear sounds too high-pitched for the human ear. The species is a relative of modern toothed whales like dolphins, porpoises and sperm whales.
Scientists discovered impressive abundance and diversity among the creatures living on the seafloor in the Clarion-Clipperton Zone — an area in the equatorial Pacific Ocean being targeted for deep-sea mining. The study found that more than half of the species they collected were new to science, reiterating how little is known about life on the seafloor in this region.
Ecologists have discovered a food web beneath the waves of French Polynesia that is both unusual and spectacular. A small channel hosts up to 700 sharks – far more than it can support based on the number of fish living there. The predators survive by feasting every winter on huge numbers of grouper fish, which swim into the channel to spawn.
A new study by an international team of scientists reveals the exact timing of the onset of the modern monsoon pattern in the Maldives 12.9 million years ago, and its connection to past climate changes and coral reefs in the region. The analysis of sediment cores provides direct physical evidence of the environmental conditions that sparked the monsoon conditions that exist today around the low-lying island nation and the Indian subcontinent.
A new study suggests that the increasing acidification of the oceans is likely to interfere with the ability of fish to reproduce. Researchers found that elevated levels of CO2, which make the waters more acidic, saw significantly lower levels of spawning. However, other mating behaviours of the same species were unaffected by the souring of the oceans.
Georgia’s salt marsh is disappearing, according to UGA scientists, and climate change is the main culprit.
A volatile arrangement of tectonic plates millions of years ago gave us the Pacific. The Pacific Ocean was born from a geological spasm that started 190 million years ago, when Earth’s crust ripped apart and fresh lava welled up from below. Now, a new analysis suggests that this seafloor birth was a lot more complex than researchers had thought.
New 3-D modeling technology has the power to scan coastlines for garbage much faster than humans can.
Nature Index 2016 Rising Stars seeks to identify the ascendant performers in the research world, using the power of the Nature Index, which tracks the research of more than 8,000 global institutions.
To be a fish in the ocean void is to glow, according to a new paper in PLOS ONE: an astounding 80% of open water marine fish can make their own light. What’s more, the trait has arisen 27 separate times in ray-finned fish lineages, a number much higher than previously realized or expected.
We, NMFS, announce a 12-month finding and listing determination on a petition to list the Caribbean electric ray (Narcine bancroftii) as threatened or endangered under the Endangered Species Act (ESA).
E/V Nautilus team find likely sea slug 5,000ft below sea off Santa Barbara. Analysis reveals foot and proboscis, making it ‘a gastropod of some kind’
