No way. I would've found that convo about sharks interesting... I would've quizzed you a bunch and maybe even ask you about other types of fish. Then I'd probably go silent too. I'm probably processing the info I gained from you or im trying to make a conversational bridge to how your passion relates to mine. It's okay to not be talking all the time hehe
I like octopus! They are smart :D and I like to watch those videos where they solve mazes, puzzles and camouflage! The dumbo octopus is cute. Cuttlefish are interesting although they're not octopus.
I don't know any cool fish facts other than I do like to watch fish move around and exist ✨
I looked up that shark you mentioned. Its big eyes jump scared me 
The most awkward convo I ever had is probably at a family get together. The other party would just say "yes and something." and there wouldn't be something interesting else that they would add. No second part/extra info to continue off of
maybe I was just too nervous and my social mask was slowly timing out
