My lecture--Snakes

On Friday, I saw a lecture. It talked about why people scare snakes. Actually, I scare snakes but I want to know some information about snake. That's why I chose this topic. In the lecture, the professor introduced how snakes eat, how they move, the legends of snake, how different people comment on snakes. In lecture, the professor introduced the dangerous snakes. Most snakes are harmless. Harm snake have three types: rear-fanged snakes, front -fanged snakes and moverable-fanged snakes. The professor gave some examples for each types. The Snakes venoms also are introduced. Snakes venoms is very complex. There are hundreds of types. I like this lecture. It is very interesting. However, I can't do presentation because I went by myself. It's so sad.
