Littoraria angulifera (Lamarck, 1822),
originally in this column on May 29,
2015. As the vernacular name implies,
Mangrove Periwinkles inhabit the
trunks and branches of mangrove
trees, in particular those of the Red
Mangrove. Periwinkles may reach 1.25
inches; they are marine snails highly
adapted at living completely out of sea
water, usually high above the intertidal
(“between tides”) zone. Mangrove
Periwinkles feed, using the teeth of
their rasping radula, on the thin film of
fungi and algae that grow on the bark
of mangrove trees. Learn more about
local mollusks at www.shellmuseum.

The first thing to
choosing this important piece of
equipment is the material. Paddles
come in many materials, but there are
four that are most commonly used.
The first, wood, makes a gorgeous
paddle, but it is heavy. Wood is ideal
for the paddler who values aesthetics
over weight. Aluminum is the primary
material for beginner’s paddles. It is
durable and inexpensive. Aluminum,
like wood, is also heavy. Fiberglass
paddles are lighter than the previous
two materials and tend to be a bit
pricier. However, for those who spend
more time on the water, a lighter
paddle could be worth the investment.
Fiberglass is also durable, so damage
becomes less of a worry. Carbon fiber is
the lightest and most expensive material
on our list. For frequent paddlers or
those who make long trips, this material
will greatly reduce fatigue and will be
worth the extra money.
One other component to consider is
stiffness. Fiberglass and carbon fiber are
stiffer than other materials. This means
that more power from the paddler is
transferred to the water with less effort.
Materials like aluminum and plastic
(not discussed here) will give slightly
with each stroke, reducing your energy
transfer. More stiffness equals less work,
and less work means more fun.
Paddles are your connection to the
water, so finding the right material
for your paddling pursuits and for
your budget is the first step to gearing
up properly for the most enjoyable
paddling experience. Buying your first
paddle is a daunting but exciting task.
Choose wisely, and have fun.

Greater amberjack is overfished and
