*understand that lobsters walk straight*
Usually they walk backward, with their claws raised in defiance, when they are facing their prey.
Lobsters can swim both forward and backwards, by flicking their tail.
Both crab & lobster can use autotonomy; I think sea stars do too.
If they weave and stumble - then it’s time to eliminate the sauce. :)
Love lobster and crab meat. Then, to find out MO, who has priority, enjoys lobster - the joy of eating just turned a tad sour.
