The life span of a barnacle?

Answer 1

Despite decades of research, many questions remain concerning the behavior of the blue crab, Callinectes sapidus. This pugnacious, bottom-dwelling predator has been the object of the most productive commercial and recreational fishery in the Chesapeake Bay for many years, yet its behavior remains mysterious. Nevertheless, we know a considerable amount about the crustacean's life cycle and habitat, during what appears to be a particularly perilous time for the species in the Bay.The average lifespan of a crab is up to three years, however the maximum age may be as long as five to eight years. about a 106 years just kidding! :p. by the way i copied and pasted so all that callinectes thingy was not me, I don't even know how to spell it!

my info:I don't think they live for long because they are mostly eaten so.....

and they are like crabs so.... about 3-4 years

Answer 2

A barnacle doesn't really have a life span. It lives until it is overrun by other plants. But it takes years for it to grow a couple inches tall and spread out a little. The barnacles let go of tiny "seeds" or eggs each year. A single plant lets go of thousands. It is a great job if a couple seeds find a good place to grow. But they are constantly fighting for space and good bacteria to feed off of. So it will either overrun other plants or be overrun.

Answer 4
