As far as i know there's only one species of animal that does not have a heart and that is a jellyfish.
Albacore tuna, anchovy and Atlantic cod are ocean animals.
the dead sea was once a 'normal' sea like the rest, but evapoation made a higher percentage of water disappear than normal seas so when that happens the salinity of the water increases the way the dead sea has gone. Its not that salt has been added from a mysterious source, it that water has been taken away.
Yes because there is so much salt in dead sea water the water is denser making you relatively lighter compared to normal water.
Not at all. Humans carry sea water inside them. That's the "normal saline" in IVs.
yes
