During the Late Cretaceous period, around 86 to 72 million years ago when dinosaurs dominated the land, the oceans hosted formidable predators beyond the familiar mosasaurs and plesiosaurs.

Recent research from Hokkaido University, published in Science, reveals that giant octopuses of the species Nanaimoteuthis haggarti likely reigned as apex hunters.

Fossilized jaws, exceptionally well preserved in solid rock, allowed scientists to estimate these creatures reached total lengths of up to 19 meters (62 feet), with bodies about 1.5 to 4.5 meters long and the rest consisting of powerful, elongated arms.

These invertebrates, equipped with eight arms, sharp beaks capable of crushing bone, and probable high intelligence, challenged the long-held view that only vertebrates topped the marine food chain.

Wear patterns on the jaws suggest they preyed on fish, crustaceans, and possibly even large marine reptiles. Their size rivaled or exceeded many contemporary predators, positioning them as formidable "Cretaceous krakens" that could ambush and overpower sizable prey through stealth, strength, and sophisticated behavior.

This discovery highlights how gigantism affected multiple lineages in nutrient-rich Cretaceous seas. Unlike modern octopuses, these ancient giants had fins and thrived as dominant carnivores, reshaping our understanding of oceanic ecosystems when dinosaurs still roamed. The findings underscore the surprising diversity and power of soft-bodied invertebrates in prehistoric marine environments.

What reveals more about lifespan than any blood test might be your balance.

Scientists have identified five simple movement tests that predict heart disease risk and mortality years before conventional screenings.

Many adults over 50 fail even one of these assessments, signaling accelerated aging.

The 10-second single-leg balance, 30-second sit-to-stand, sit-rise test, push-up count, and grip strength together provide a clear snapshot of biological age.

Failing these tests isn’t a sentence—targeted exercises can reverse declines in weeks.
