Last Orca Survivors Spotted Off Scotland's West Coast

A rare sighting off Scotland's west coast has recorded the last known members of the UK orca group, the West Coast Community, with only two individuals, John Coe and Aquarius, seen together after years of decline. The sightings highlight the ongoing challenges faced by marine species, including chemical contamination and habitat threats, while also marking significant discoveries like the first breeding site for the critically endangered flapper skate in Orkney.

Orcas Dominate and Attack Great White Sharks in the Ocean

A pod of orcas off Mexico has developed a sophisticated hunting strategy to immobilize and prey on juvenile white sharks, primarily for their nutrient-rich livers, showcasing their advanced intelligence and social learning. This behavior, observed through detailed footage, highlights the orcas' ability to exploit sharks' tonic immobility, and may indicate a developing prey specialization within this pod.

Orcas Terrorize and Hunt Great White Sharks in Stunning New Footage

Videos from Mexico reveal orcas hunting and eating the livers of young great white sharks, showcasing a specialized predation behavior that has been observed in other regions like South Africa. The behavior involves flipping sharks to induce tonic immobility, allowing orcas to extract the nutritious liver, and appears to be a learned, group-specific strategy that may be influenced by changing ocean conditions.

Great White Sharks Face Their Deadliest Rival

Great white sharks, long the ocean's top predators, are now being preyed upon by orcas in Australian waters, marking a significant shift in marine predator dynamics. Evidence shows orcas targeting sharks' livers with surgical precision, which could lead to declines in shark populations and broader ecological impacts. This behavior, previously observed in South Africa, is spreading, indicating a potential change in the marine food chain.

Dolphins and Orcas Reach Critical Evolutionary Milestone Toward Land Return

Research shows that dolphins and orcas have crossed a point of no return in their evolution, making it biologically impossible for them to return to land due to their highly specialized marine adaptations, which are now irreversible. This extreme specialization, while beneficial for ocean life, also makes them vulnerable to environmental changes such as climate change and pollution.
