Description
Panulirus argus inhabits western Atlantic coastal waters
from North Carolina to Brazil; the planktonic larvae are
potentially capable of colonizing the entire species range
during their greater than six month existence. Alternatively
the larvae may, despite their potential for dispersal, settle-out
close to the site at which they were hatched. Restriction endonuclease analysis of P. argus mitochondrial
DNA (mtDNA) suggests that the species range is divided into
local populations. One specimen from Key West, Florida, showed a unique cleavage pattern for at least one endonuclease
(BstEII) when compared with twenty-three individuals from the
middle and upper Florida Keys. When the lower Keys sample
was compared to the middle and upper Keys samples, a tenfold
increase in the number of mtDNA base changes was observed
in contrast to the same comparison for an upper Keys sample.
