This type of fuels are formed due to the dumping of dead prehistoric organisms like dinosaur and others under the soil under a tremendous pressure and very high temperature, where they are acted upon by bacteria and other chemicals to reduce them into petroleum and coal. These are totally non renewable and they are getting expensive over days due to shortage of availability.

A boy brought a pair home as pets.

Explanation:

As small organisms will not have any major  adaptations for moving quickly or flying to whole another country, hence it is not possible for the snail to travel from Africa to Florida with small animals. Getting stuck on the airplane wing is also not correct as they would have been wiped out by the wind pressure or might have not be able to survive. Hence, the most logical explanation for the snail to get transported to Florida is by a boy who might have brought them as a pet.
