Of course, they seem to move much more slowly and with more margin.
In 2005 the European Space Agency's Huygens probe will arrive there and astronomers have announced that it is possible to find an ocean of hydrocarbons or an ice field when it enters Titan's atmosphere. They have done computer simulations to know what they expect if it is an ocean.
According to studies conducted by radio signals, 75% of the satellite could be covered by a sea of hydrocarbons. The reflected signals have been used to check if the liquid mass is very mixed, data that coincide with those obtained in the simulations. Astronomers expect the probe to clarify whether they are correct or not.
