With climate change happening around the world, now more than ever it is important to understand the critical role oceans play in our everyday lives. Celebrate our ocean planet and learn simple ways you can make a difference during Mystic Aquarium’s World Oceans Day on Saturday, June 5.

With assistance from the Association of Zoos & Aquariums and The Ocean Project, this year’s celebration honors the 50th anniversary of Dr. Seuss’ “One Fish, Two Fish, Red Fish, Blue Fish” book. From 11 a.m. to 3 p.m., kids will receive activity booklets related to the book, can participate in an ocean-themed spelling bee and will receive special prizes, such as bookmarks, pins or fake tattoos. Kids can also get their faces painted, color their very own fish crown and make an estuary in a bottle, which contains oil, water, food coloring and plastic fish to show how estuaries are formed. Kiki Latimer, author of the new book, Bubble Butt!, about Charlotte the green sea turtle that lives at Mystic Aquarium, will be reading in front of Charlotte's exhibit on the main exhibit floor. Illustrator Bunny Griffeth will join her.

Adults will learn about rain collection barrels and ways to halt the flow of pollutants to Long Island Sound during EnviroScape demonstrations. Aquarium staff will also share conservation-minded home improvement ideas and ways water can be reused and conserved. In the Marine Theater, guests will see a special "Cat in the Hat"-themed sea lion show.

All activities are free with aquarium admission.
