Accurate predictions of predator behavior remain elusive in natural settings. Optimal foraging theory predicts that breath-hold divers should adjust time allocation within their dives to the distance separating prey from the surface. Quantitative tests of these models have been hampered by the difficulty...
What are the largest great white sharks ever recorded? Just how big can these ocean giants really get? This question is one of the most hotly debated topics in marine science, and it’s surrounded by plenty of “big fish” stories and myths. Over the years, numerous claims of massive gre...
Analysis of the fossils of marine mammals that lived in the oceans around 7 million years ago have provided the most detailed insight yet into the kind of prey it targeted. Distinctive scrape marks and wounds left on bones by the shark’s huge, serrated teeth suggest it preferred hun...
Megalodon, the largest shark that ever lived, is famous for its gigantic, human-hand-sized teeth. However, there is little fossil evidence of its whole body. International researchers in collaboration with the University of Zurich used an exceptionally preserved specimen to create a 3...
The largest marine animal ever killed by hand harpoon was a blue whale killed at Twofold Bay, New South Wales, Australia, in 1910 that was 29.57 m (97 ft) long. Unique physical characteristics Owing to its huge dimensions, with an average body length equivalent to two double-decker buses ...
Tracking apex marine predator movements in a dynamic ocean. Nature 2011, 475, 86–90. [Google Scholar] [CrossRef] Andrzejaczek, S.; Lucas, T.C.D.; Goodman, M.C.; Hussey, N.E.; Armstrong, A.J.; Carlisle, A.; Coffey, D.M.; Gleiss, A.C.; Huveneers, C.; Jacoby, D.M.P....
The researchers calculated that the likeliest body plan for megalodon wouldn’t have been that of a stout, tanklike great white but rather a more streamlined fish, such as a lemon shark. In this discovery, Shimada said, his team also stumbled upon a larger pattern in marine biology. ...
cane fields. However, there is no evidence that it has ever been a successful biological control, and it is now considered a nuisance species wherever it has been introduced. It successfully competes with native amphibians for food and habitat. ...
(n = 7 tiger sharks equipped with camera tags only), including the first-ever deployment of a 360-degree camera borne by a marine animal24. Satellite-tagged tiger sharks traversed 4177 km on both regions of The Bahama Banks, up to 11.3 km/day, with a total of 20.6 km ...
primary production in seagrass. Additionally, a large portion of seagrass meadows’ SOC accumulation can be allochthonous material, which originates from other marine or terrestrial ecosystems and is subsequently transported to the seagrass meadow4,9. While a portion of allochthonous SOC is likely not...
