Phelps and his wife, Nicole Johnson, took their little guy on a trip to the OdySea Aquarium on Thursday, and the adorable 1-year-old was absolutely fascinated by the different sea creatures on display -- including a stingray that came up to the glass to give Boomer a close look at its unique features.
"I think @boomerrphelps love for sea life might be as great as our is," Johnson wrote, tagging her husband in the caption to a slideshow of Boomer's cutest moments from the visit. "Lil man ran from tank to tank to see what was next laughing and yelling! I told him stingrays were one of my favorites and he happened to find one he could stand face to face with!"
"During my shark week experience, I was lucky to meet some seriously cool people! However, one stands out, ‘Doc’ Dr. Samuel Gruber a legend of shark science," Phelps captioned a pic of himself and his wife sitting on the deck of a boat with Gruber, who is one of the co-hosts of Shark School.
Johnson also wrote that, during her husband's Shark Week experience, she too developed a love for the oft-maligned ocean predators, thanks to Shark School's other host, Tristan Guttridge.
"While @m_phelps00 was filming I was able to pick @tristanguttridge brain about the amazing sharks in Bimini... at one point they even allowed me to sit on the bottom watching MP free dive with reef sharks," she wrote, alongside a photo of her and Phelps in wet suits, sitting on a boat in the ocean. "Needless to say I'm in love with sharks and I can't wait to dive with Hammers #bucketlist #sharkweek."
