entpuppen vs schlüpfen
to slip / hatch
'schlüpfen' and 'sich entpuppen' can both have to do with the development of animals. 'schlüpfen' is used when a young animal leaves an egg, for example a bird or an insect. 'sich entpuppen' is used for insects when they leave the pupal casing and become adult animals. The words can be confused because in both cases an animal comes out of a casing or shell. The important thing is the stage: 'aus dem Ei schlüpfen' (to hatch from the egg), 'aus der Puppe sich entpuppen' (to emerge from the pupa).
entpuppen
Im Glas hat sich die Raupe später als schöner Schmetterling entpuppt.
In the jar, the caterpillar later emerged as a beautiful butterfly.
schlüpfen
Nach zwei Wochen schlüpften die Küken aus den Eiern.
After two weeks, the chicks hatched from the eggs.
