This 9 July 2020 video says about itself:
Croatia has a high diversity of snakes by European standards. Some species are venomous, like the Nose-horned viper (Vipera ammodytes) and Eastern Montpellier snake (Malpolon insignitus).
Living Zoology went for a short trip to Croatia and found both. Nose-horned viper is a front-fanged snake and it was the first venomous snake we found together. That’s why it is in our logo. Malpolon is a rear-fanged species and we found it for the first time during this trip.
