M: I really appreciate your filling in on yesterday’s lecture.
W: No problem. I thought you might want to go over it together. And, anyway, it helps me revtew.
M: I am. Thanks. So, you said she talked about squid? Sounds a little strange  ....
W: Well, actually, it was about the evolution of sea life — a continuation from last week. The octopus and the squid descended from earlier creatures with shells. They survived by shedding their shells—somewhere between 200 and 500 million years ago.
M: That’s a pretty long span of time.
W: I know. That’s what she said, though. To be precise: "Exactly when they emerged is uncertain...and why is still unexplained."
M: Some squid are really huge. Can you imagine something that big ifit still had a shell?
W: Actually, it’s because they lost their shells that they could evolve to a bigger size.
M: Make sense. But some are really huge. I’ve read about fishermen that caught squid that weighed over a ton. Did she talk about how that happens?
W: Not really. But she did mention some unusual cases. In 1933 in New Zealand they caught a squid let’s see here it was twenty-two yards long. Its eyes were eighteen inches across. Can you imagine?
M: Reminds me of all those stories of sea monsters.
