Ocean Warming Endangers Microbe Crucial for Earth's Oxygen

A new study warns that rising ocean temperatures threaten Prochlorococcus, Earth's most abundant photosynthetic microbe, which produces nearly a third of the planet's oxygen. The microbe's optimal temperature range is 19-28°C, and temperatures above 30°C significantly reduce its growth, potentially leading to a decline in its population and impacting global oxygen levels and marine food webs. The study highlights the importance of understanding microbial responses to climate change and the potential shift in oceanic ecosystems.

Scientists Drop Cow into Deep Sea, Encounter Sleeper Sharks and Unexpected Visitors

Chinese marine researchers' experiment to study whale carcass scavenging in the South China Sea was disrupted when eight Pacific sleeper sharks appeared, marking their first confirmed sighting in the region. The sharks exhibited unusual behavior, including a queuing feeding system and eye retraction, sparking scientific questions and internet memes about their 'smiles.' The event highlights gaps in understanding deep-sea animal distribution and behavior amid shifting ocean conditions.

Zooplankton: The Unexpected Climate Change Ally

Zooplankton, including copepods, krill, and salps, play a crucial role in mitigating climate change by consuming phytoplankton and transporting carbon to the deep ocean, effectively acting as a biological pump that reduces atmospheric CO2 levels. However, climate change and industry activities threaten these vital species, potentially undermining their climate-regulating functions.

Orcas Devour Liver of World's Largest Shark in Shocking Video

A gruesome video captured by James Moskito, CEO of Ocean Safaris, shows a pod of orcas attacking and sucking out the liver of a whale shark, the world's largest fish. This rare footage demonstrates the orcas' ability to target large prey and consume only the nutrient-rich organs. Orcas are known to dine on the livers of great white sharks, using a technique that induces tonic immobility in the shark before surgically removing its vital organs. The video highlights the potential cultural transmission of knowledge among orca pods and sheds light on their dietary preferences and hunting strategies.
