I love the ocean so much, it's so calming.
Yes, I agree.  It is beautiful, and it composes much of our planet's hydrosphere.
Do you know much of the hydrosphere it composes?
Yes.  It covers approximately 71% of the Earth's surface, and 90% of the Earth's biosphere.
That's so interesting. I've always been fascinated with the sea, but it is also frightening. Have you heard of thalassophobia?
Yes, the fear of sea travel.  It can be frightening to consider the vast sea.  
What with giant squids and all.
The giant squid belongs to the genus Architeuthis.  It can grow to a tremendous size!
