A baby caiman has found a new home at a Lithuanian zoo after its previous owner tried to sell it online, apparently upon realizing that the pet reptile he was raising in his bathroom wasn't a harmless lizard.

Officials at the Kaunas zoo said authorities confiscated the spectacled caiman from a student who had posted an online advertisement for a large lizard.

They said the student had kept it for several months but, stunned by how fast it was growing, decided to get rid of it. Lithuanian law prohibits raising dangerous animals at home.

The 1.3-kilogram (2.8 pound), 63-centimeter (25-inch) caiman, named "Croc," was handed to the zoo, where visitors could see it for the first time Wednesday.

It wasn't immediately clear how the student had obtained the reptile.
