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.
According to Wikipedia: Hedgehogs have a relatively long lifespan for their size. Larger species of hedgehogs live 4â7 years in the wild (some have been recorded up to 16 years), and smaller species live 2â4 years (4â7 in captivity), compared to a mouse at 2 years and a large rat at 3â5 years.
