noun, m. | -ου
4.55 · Animals · Reptiles and Other 'Creeping Things'
frog tailless amphibian with a squat body, moist smooth skin, and long hind legs for jumping; about 70 mm long; brown or olive-green; develops from tadpole; Rana esculenta (Edible frog) or Rana punctata (Spotted frog) In this only reference to frogs in the NT, the connotation is of something unclean and abhorrent. In a number of societies, however, frogs are regarded as very valuable and worthwhile animals, since they are often an important source of food. On the other hand, in such areas there are usually certain types of frogs or toads which are particularly poisonous and whose names, therefore, do carry bad connotations.
