The earliest appearance of gigantic lamniform #sharks has now been pushed back by ~15 Ma (upper Aptian, ~115 Ma) with the discovery of enormous cardabiodontid shark remains from northern Australia.🦈🧪

50 years on from the release of movie blockbuster Jaws, our shark expert @thesimslab.bsky.social @sotonoceanearth.bsky.social debates the so called 'Jaws effect', charting the fortunes of the 'great white' for @theconversation.com.

Jaws helped spur a fishing frenzy – so how have the world’s sharks fared since the 1975 release?
The film made us afraid to go back in the water. It ultimately gave sharks more to fear from us.

Herculean collation of >12K megafauna tracks, >100 species, reveals 75% overlap of critical habitats with shipping, fishing, pollution or warming. Protection targets not enough to safeguard megafauna.

Professor David Sims, MBA senior research fellow and a senior author of the study, explained that the study’s goal was to track the day-to-day movements of diverse #MarineMegafauna globally over many years to identify important habitats used for behaviours like foraging, resting, and migration.

New research backed by the UN highlights the benefits of tracking marine megafauna for #marine #conservation 🦈

However, results reveal that proposed plans to protect 30% of the ocean by 2030 will be insufficient for their conservation.

New research from @thesimslab.bsky.social in @ecol-evol.bsky.social - 🦈🌊
Unlocking the mystery of baby #whaleshark birthing grounds - Extreme environments like #OMZs provide safety from predators & a rich food supply, crucial for neonate survival.

(a) Recorded sightings of whale shark neonates globally (black points). (b) Image of neonatal and adult whale sharks from Large Marine Vertebrates Research Institute Philippines group (b) and Marty Snyderman (b). (c) Whale shark neonates and sea surface temperature (SST, °C averaged for 2005–2019). (d) SST recorded from neonate locations and 10 randomised runs. (e) Whale shark neonates and Chlorophyll-a (Chl-a, mg m3 averaged for 2005–2019). (f) Chl-a at 0 and 100 m depths recorded from neonate locations and 10 randomised runs. (g) Whale shark neonates and current velocity (UV) at 0 m depth (ms−1, averaged for 2005–2019). (h) UV recorded from neonate locations and 10 randomised runs. (i) Whale shark neonates and dissolved oxygen (DO) concentration at 100 m depth (μmol L−1, averaged for 2005–2019). (h) DO concentrations at 0 and 100 m depths recorded from neonate locations and 10 randomised runs. In (d, f, h) and (j) each point represents a single sighting or randomised location, the solid black line is the median value of randomised locations, the dashed black line the median of the observed sightings for each depth, and the violin displays the density distribution of all locations. IUCN whale shark distributions are shown in white in each map and with a black outline in (a).
