    @Le_balayeur @YMichat @mr_uchihaaa Donc pas de ressentiment mal placé, es-tu en mesure de m'indiquer quel article scientifique revu par des pairs suggérait pour le bestiau un métabolisme ectotherme ? J'en doute car il n'y en a pas, le dernier en date est de Ferron.https://t.co/A0KBejCyWV

    @BrettHodinka Hi Brett! There has been a couple of swim speed estimates, although body mass tends to be used to calculate swim speed. Both estimated cruising speeds of 1.34-1.4 m/s. There may be more work on this coming soon ;) Paper 1: https://t.co/fQknQDb28U Paper 2: https://t.co/4x77WQnjAr

Abstract Synopsis

  • The study suggests that some extinct large predatory sharks, like Otodus Megaselachus megalodon, likely had regional endothermy (warm-bloodedness in specific body regions), which helped them achieve gigantism and stay actively hunters.
  • Researchers used multiple approaches—such as isotopic analysis, swimming speed estimates, and new methods for assessing energy use—to support the idea that these sharks were endothermic, challenging previous views that saw them as cold-blooded.
  • The findings imply that our understanding of ancient shark climates and evolution needs revision, as the presence of endothermy in these sharks impacts interpretations of past temperatures and how large predatory animals evolved to be active and massive.]
