Cape and Australian fur seals show dramatic increases in heart rate hours after returning to land, according to new research. The surges may help the animals recover from the physical stress of prolonged underwater foraging.

Researchers have discovered 24 previously unknown species of deep-sea amphipods in the Clarion-Clipperton Zone of the central Pacific Ocean, including an entirely new superfamily. The findings, detailed in a ZooKeys special issue published on March 24, highlight previously unknown branches of life in one of Earth's least explored ecosystems. The work advances efforts to catalog biodiversity amid growing interest in deep-sea mining.

Researchers have documented sperm whales colliding head-on with their heads for the first time using drone footage from the Azores and Balearic islands. The behavior, observed among sub-adult whales, supports longstanding sailor accounts of aggressive whale encounters. The findings were published on March 23 in Marine Mammal Science.

A newly discovered deep-sea chiton has been named Ferreiraella populi through a global online campaign that drew over 8,000 suggestions. The species, found in Japan's Izu-Ogasawara Trench, honors the public's involvement in its scientific description. This effort highlights innovative ways to engage people in ocean biodiversity.

A new review in Science highlights how calcifying plankton, tiny marine organisms that form calcium carbonate shells, are underrepresented in climate models. These plankton play a crucial role in the ocean carbon pump, pulling carbon from the atmosphere and storing it in deep waters. The omission could lead to underestimating the ocean's response to climate change.
