Also, what would our individual life look like as a trajectory? I've been having the thought that our motion of life is a spiral zooming in a particular direction, from the side view, looking like a sinewave (the ups and downs of life), but this trajectory might not be in a straight line. Maybe it is in a circle.
Believe it or not, lobster and crabs are crustaceans and are a part of the arthropod family, which include caterpillars, cockroaches, and spiders!
