Christ the King Catholic School seventh grader, Isabella Smith, carefully holds a blue crab at the Dauphin Island Sea Lab, while classmates, Olivia Barter, left, and Claire Tomberlin look on. The annual seventh grade field trip to the Sea Lab included the hands on experience at the touch tanks, a discussion on invertebrates, the dissection of a squid, and a visit to the Estuarium, where they were able to see fish, turtles, alligators and other native species up close.
