Penguins are able to dive to a depth of 150-200 meters. Penguins do not need fresh water - they are able to drink salty seawater, as special glands in their body filter out salt.
The safari and zoo in Ramat Gan near Tel Aviv is the largest zoological center in the Middle East. Scientific research is carried out at the zoo, and there is a veterinary clinic. The territory of the zoo is beautifully designed and conveniently equipped. My biggest tip before visiting the zoo: Don't be lazy to walk.
