Very beautiful colored Jellyfish in an aquarium
Jellyfish or sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are not mobile, being anchored to the seabed by stalks. The bell can pulsate to provide propulsion and highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, the planula larva can disperse widely and is followed by a sedentary polyp phase.

Kyiv Metro in darknest night
The capital of Ukraine, is situated on the river Dnipro and has about 2.6 million inhabitants. Its metro system is a typical ex-Soviet three line system (total length 67.6 km in Nov 2013) with all lines meeting in the city centre to form a triangle. Older stations in the city centre were built in the underground palace style similar to Moscow's metro. The network is entirely underground on the right bank of the river Dnipro (Dnieper) with two bridge-crossings of the river and one at-grade stretch on Line 1 on the left bank.
