TIPS ON NAVIGATING<br />
DOLPHIN BEHAVIOR<br />
Amber Kuehn, Marine Biologist<br />

I thought every 12 year old had <strong>the</strong> keys to a motor boat,<br />
and threw a cast net to catch a mullet to feed <strong>the</strong>ir pet<br />
dolphin named Dolly. <strong>The</strong>re are things that you observe<br />
as an adult that you had seen as a child, but never<br />
thought anything <strong>of</strong> it…<br />
All <strong>of</strong> <strong>the</strong> cetaceans residing in Beaufort County are<br />
Atlantic Bottlenose Dolphins (Tursiops, truncatus)<br />
When dolphins approach boats for food<br />
It was always exciting to feed Dolly <strong>the</strong> fish, which she<br />
would only swallow head first. Dolphin swallow <strong>the</strong>ir<br />
food whole, so it had to be just <strong>the</strong> right size and it went<br />
down smooth head first, as fish are streamlined in <strong>the</strong><br />
forward direction. However, IT IS A FEDERAL OFFENSE<br />
TO FEED MARINE MAMMALS AFTER 1992. <strong>The</strong> federal<br />
government amended <strong>the</strong> Marine Mammal Protection<br />
Act <strong>of</strong> 1972 to say that no food <strong>of</strong> any sort shall be fed to<br />
any marine mammal in <strong>the</strong> United States. This includes<br />
polar bears, sea otters, manatees, sea lions, seals,<br />
whales, dolphins, etc.<br />
Due to <strong>the</strong> fact that dolphins do not taste <strong>the</strong>ir food, <strong>the</strong>y<br />
will eat anything that will fill <strong>the</strong>ir bellies. <strong>The</strong>y are lazy,<br />
and would prefer to open <strong>the</strong>ir mouths to beg from boats<br />
ra<strong>the</strong>r than catching <strong>the</strong>ir own food. <strong>The</strong>re is obviously<br />
less nutrition in a Twinkie than a fish, but <strong>the</strong>rein lies a<br />
larger issue, no fresh water in a Twinkie (A Twinkie is an<br />
American snack cake, marketed as a “Golden Sponge<br />
Cake with Creamy Filling”). A dolphin is a mammal and<br />
cannot drink salt water. <strong>The</strong>y stay hydrated by eating<br />
fish. A fish can drink salt water all day long and excrete<br />
<strong>the</strong> salt in its urine and through its gills; a fish is full <strong>of</strong><br />
fresh water. <strong>The</strong> raw fish at <strong>the</strong> sushi bar is not salty until<br />
you add <strong>the</strong> soy sauce. At Hudson’s Seafood, you don’t<br />
request your fish to be prepared without any salt, butter,<br />
seasonings…Just fish plus heat will be very bland. Also,<br />
it is best that dolphins do not hover around boats with<br />
spinning blades.<br />
When dolphins blow several times at once<br />
<strong>The</strong>y are so graceful and amazing to watch as <strong>the</strong>y glide<br />
through <strong>the</strong> May River. When <strong>the</strong>y break <strong>the</strong> surface<br />
<strong>of</strong> <strong>the</strong> water to brea<strong>the</strong>, <strong>the</strong>y exhale (<strong>the</strong> blow that<br />
you hear). <strong>The</strong>ir name should be <strong>the</strong> Atlantic Bottle<br />
Mou<strong>the</strong>d Dolphin, because <strong>the</strong>ir<br />
mouth is <strong>the</strong> rostrum or projection<br />
on <strong>the</strong> front <strong>of</strong> <strong>the</strong>ir face, and <strong>the</strong><br />
nose is actually a blowhole on<br />
<strong>the</strong> top <strong>of</strong> <strong>the</strong>ir head! When your<br />
nose is a slight dent on <strong>the</strong> top <strong>of</strong><br />
your head with two muscles called<br />
monkey lips that open and close it<br />
to brea<strong>the</strong>, what is still in <strong>the</strong> dent<br />
when <strong>the</strong> dolphin comes up for<br />
air? Water! So will it inhale first?<br />
Or exhale first. If you answered<br />
exhale first, you are correct. <strong>The</strong><br />
exhale pushes that water out<br />
