Why do octopuses ink




















Sea Camp offers three one-week sessions for boys and girls ages and two three-week coed sessions for teens ages Our hand-picked counselors and instructors create an atmosphere of fun and excitement while leading campers on a host of ocean adventure, marine biology, and social summer camp activities. Rules for participation in Guided Discoveries programs are the same for everyone without regard to race, color, national origin, sex, or handicap.

But the benefits of spending a week or more away from parents and meeting kids from all walks of life extends beyond the fun and friendships. Studies by the American Camp Association show that summer camps actually help prepare kids for adulthood. Campers are shown to exhibit growth in self-confidence and the ability to learn new activities and make new friends that will serve them well through adulthood.

For example, an octopus may attempt to flee an attacker by jetting away, and then try to camouflage itself on the sandy bottom.
