As power flows through submarine cables, law of the sea must evolve

Beneath the surface of the world’s oceans lies an infrastructure so essential, modern life would stall without it – yet so invisible it rarely enters public debate. Submarine cables, slender fibre-optic systems laid across the seabed, carry over 95 per cent of global internet traffic, transmitting the data that underpins financial markets, diplomatic exchanges and everyday communication. What appears to be neutral infrastructure is, in fact, a deeply political system – one that exposes a...

Torpedo-Shaped Device Found Near Strategic Lombok Strait Raises Surveillance Concerns

A torpedo-shaped device discovered near the Lombok Strait, a key deepwater passage between the Pacific and Indian oceans, has raised concerns about undersea surveillance capabilities. The strait is closely monitored by the United States and Australia. China stated it conducts marine research in accordance with international law and noted such equipment could drift due to malfunctions. Analysts said such devices could map seabeds, collect oceanographic data, monitor naval traffic and identify routes or infrastructure critical in a crisis.

Giant Octopuses May Have Ruled Ancient Oceans 100 Million Years Ago

Scientists from Hokkaido University have analysed fossil jaws suggesting giant octopuses up to 19 metres long ruled ancient oceans 100 million years ago. The research challenges the long-held view that vertebrates like fish and reptiles were the largest ocean predators, indicating these cephalopods were powerful predators with strong arms and beak-like jaws capable of chewing shells and bones.

Giant Octopus Fossils Reveal Ancient Kraken-Like Predators Dominated Oceans

Scientists have identified ancient octopus fossils belonging to genus Nanaimoteuthis, particularly Nanaimoteuthis haggarti, which may have grown up to 19 meters (62 feet) long—longer than a bus and possibly the largest invertebrate ever recorded. Analysis of 27 fossilized beaks reveals these creatures were apex predators in Cretaceous oceans, using intelligence and crushing bite force to dominate marine ecosystems alongside mosasaurs and plesiosaurs.

Giant Ancient Octopuses May Have Been Top Ocean Predators 100 Million Years Ago

Researchers from Hokkaido University in Japan have analyzed exceptionally preserved fossil jaws from 100 million-year-old octopuses, estimating body lengths of 1.5-4.5 metres and total lengths including arms of 7-19 metres. The findings challenge the long-held belief that ancient ocean predators were exclusively vertebrates, suggesting giant cephalopods were powerful predators capable of consuming hard-shelled prey.
