Talk:Shark

Something I noticed
In the fossil record section, it says that the Hybodonts first appeared around 320 million years ago (around the mid carboniferous), but in the actual article about them, it says that started appearing in the late devonian, which was millions of years before the carboniferous. So, which one is the correct one?Blue Jay (talk) 10:27, 21 February 2022 (UTC)


 * I know i'm very late, but the first hybodonts were Roongodus and Lissodus from the late devonian. Abdullah raji (talk) 04:14, 13 January 2024 (UTC)

Distribution
I would like to know the distribution of sharks around the world. There doesn't appear to be a map. I might of missed a comment in the text if it says "sharks are found everywhere". I think of them as warm water species, so I wonder if they are found in polar sees. If my belief is incorrect, I'd like a little more information. Additional to that, is the effect of climate change on the ranges of marine life. Humpster (talk) 20:11, 31 January 2024 (UTC)

Under Physiology > Thermoregulation, change "... and the scalloped hammerhead close its mouth and gills when they dives to depths of around 800 metres, holding its breath till it reach warmer waters again" to "... and the scalloped hammerhead closes its mouth and gills when it dives to depths of around 800 metres, holding its breath until it reaches warmer waters again".
