I wonder if there is a lobster that survived her.

Lobsters are long-lived, they don't age (in the sense of slowly losing their fitness - senescence) and they only die when they grow too big and suffocate during moulting, or possibly catch some infection, or get killed by other animals/people.

A 105 y.o. lobster is plausible.

I went looking for information on the oldest known lobster, and found this article about a 20lb lobster named George who was estimated to be 140 years old. Neat!

Early reports by European colonists in New England suggest some of the lobsters back then were far bigger than today.
