The Vegan Snow Lizard is a creature known for withstanding extremely cold temperatures.
It presumably lives in a snowy, cold climate, didn't eat animals or animal by-products, and is a reptile. From the way it has been mentioned - "a Vegan Snow Lizard"- it seems likely there is more than one of these species, possibly many of them.
The Vegan Snow Lizard is mentioned in the radio series and in the second book, The Restaurant at the End of the Universe. Both times, it is mentioned in relation to Zaphod Beeblebrox , and his ability to be cool.
In the Primary Phase of the radio series, Zaphod says: "I’m going to be so unbelievably cool about it it would flummox a Vegan Snow Lizard". In the second book, it is mentioned that Zaphod said something "in a voice that would make a Vegan snow lizard feel chilly".
