The hydrogen gas that makes up most of the atmosphere slowly changes to liquid with depth as the pressure increases. Below the liquid hydrogen rests the heavier liquid helium. Deep in the depths of the body of Saturn, the hydrogen is then under tremendous pressure, and is transformed to liquid metallic hydrogen.
The African Pygmy hedgehog, or common pet hedgehog, is a small, solitary and mostly nocturnal mammal with quills. Hedgehogs appeal to people looking for an unusual, quirky pet that is also cuddly, quiet and odorless. Typical costs: Hedgehogs range in price from about $70 to $250, depending on the hedgehog's age, color, and temperament. 1  Some breeders offer hedgehog starter kits for around $75 that include a cage, wheel, a hiding place, water bottle, feed bowl and food, and some shavings. 2  Hedgehogs live between four and six years.
The European hedgehog (Erinaceus europaeus: Linnaeus, 1758), also known as the West European hedgehog or common hedgehog, is a hedgehog species found in western Europe, from Iberia and Italy northwards into Scandinavia.s a result, extensive hedgehog-control programs are under way in some parts of the country, killing thousands of them. To judge by roadkill counts, North Island hedgehogs were at their highest numbers in the 1950s. Since then, roadkill counts have fallen dramatically from about 50/100 km to less than 1/100 km.
