1. Deep-Fried Scorpion

In China and Laos, scorpion fried whole and with the stinger intact is considered a terrific snack. The less bold should try the Chinese snack zongzi, a rice dumpling wrapped in bamboo leaves.

2. Deep-Fried Tarantula

The Cambodian tarantula is the size of your hand, and it's eaten whole. This includes the abdomen, which contains a brown paste consisting of organs, maybe eggs, and excrement. Instead, you might want to focus (quickly) on the fresh mango, which is served here peeled, sliced and on a stick.

3. Deer Penis

In several countries, deer penis is ingested for its therapeutic properties. In China, it's served dried and whole or in a variety of fully prepared and sometimes elaborate dishes. Vegetarians might prefer roasted corn on the cob.

4. Escamoles

Mexican cuisine is known for its grasshoppers, but there are other insect dishes on offer, too. For instance, the eggs of the giant, black Liometopum ant (escamoles) are harvested from the agave plant (yup, the same plant used to make mezcal or tequila) and often eaten in a taco with guacamole. They lend a surprising buttery, nutty flavor. An alternative is the straightforward quesadilla (cheese, vegetables and chicken or beef wrapped in a corn or flour tortilla).
