Problemsnails we have some kind of huge garden snails, Ask an Expert

Academics

Problem:

Snails... We have some kind of huge garden snails appearing lately (read since the last 10 years or so). Try as one might, it's impossible to avoid them when driving. These snails do not appear to have red blood - I doubt they have blood at all. Wikipedia tells me blood's red color is due to hemoglobin - which serves to transport oxygen.

Required:

Question 1: How do snails (and any other animals that do not have red coloured blood) get oxygen?

Question 2: Do such animals need no oxygen at all? Please clarify your answer.
