Questions & Answers

Q: Why do platypus teeth look so strange?

The teeth of a platypus are unique and do not have cusps because they are adapted for sensing invertebrates in the mud. The teeth have a rubbery texture and a network of nerves to aid in this process.

Q: How does venom travel in certain animals?

Venom is produced in a gland and travels along spines, serving as a defense mechanism. It is believed to deter other males from approaching.

Q: How many DNA samples are stored at the Chicago Field Museum?

The museum stores approximately 70,000 DNA vials in each tank, totaling around 70,000 specimens. These samples are vital for research purposes and can be loaned to scientists conducting valid projects.

Q: Why is it important to collect DNA samples before preserving specimens?

Formalin, a preservative used to pickle specimens, can damage DNA. By collecting tissue samples before preservation, the DNA remains intact and can be used for future studies and research.
