The life history of the Argentine Black And White Tegu Tupinambis merianae part 1. Video made by my father, Bert Langerwerf using two VCR's while sitting on the living room floor in front of the TV. Narrated by my mother. The music is Argentine tango music. But there might also be some Finnish tango music. I grew up listening to this music, including the funny hissing and beeps. They were recorded in the 70's using a world radio, hence the low quality. Put online for future generations of herpetologists.
