Mote Marine Laboratory & Aquarium
The Mote Marine Laboratory is a not-for-profit group of research and rehab centers with a pretty darn cool aquarium.
An aquarium is a haven for both the scientific minded and casual viewers alike, and everyone in between. I haven't yet met anyone who dislikes aquariums, and I don't expect to because they're such wondrous places. Walking into an aquarium is like stepping into an entirely new world filled with some of the largest and smallest, brightest and dullest, most fascinating and most commonplace creatures in existence, and the dark ambiance and reflections from the water dancing on the walls create a wholly unique atmosphere in which to view them.
Living in Florida, one would expect aquariums to be relatively ubiquitous, but such is not the case. They're certainly more common than in other non-coastal states, but chances are you will have to drive out of your way to get to one. The largest aquarium in Florida is, fittingly, The Florida Aquarium, but that's certainly not your only option. If you're into Marine Biology and its tangential fields, you might want to check out the Clearwater Marine Aquarium. If you're looking for an upscale family experience, Sea World would likely be your best option. If you want a great time where you can see some of the state's most unique and interesting creatures without walking three miles from end to end, I'd suggest the Mote Marine Laboratory's Aquarium.
Mote Marine Laboratory was founded in 1955, so they're not exactly new to the game. Nor have they gone the route of most commercial aquariums, trying to get bigger and more famous by modifying quantity, rather than quality. Mote doesn't have the glitz and glamor of your Shedd Aquarium or Monterey Bay Aquarium, but they're very professional and very knowledgable, and serious about what they do. The volunteers at the aquarium are not afraid to address you if you're looking at an exhibit, and aren't afraid to impart a bit of knowledge about what you're looking at, either.
Though they may be lacking in size, they're certainly not lacking in variety. Mote includes most of the best exhibits that the Florida Aquarium has, with a bunch more that they don't. They have saltwater fish, freshwater fish, octopi, seahorses, giant spiny lobsters, various snails and slugs, sharks, eels, grouper, sharks, Tarpon, Snook, the majestic Cuttlefish, and, here's the kicker: a dead Giant Squid. If you're into squids or mysterious sea life in any aspect, this is something you should not miss.
Furthermore, there's another building across the street. This is where they keep the big guns. It contains a few Manatee, a couple Sea turtles (big ones), an albino Loggerback turtle, and a few Dolphins. It's less formal than most aquariums also, so it's somewhere you can go and spend hours just watching what the animals do. I had a fantastic time for at least half an hour just watching the Dolphins race back and forth, doing 180 degree turns on a dime, jumping out of the water, and generally playing around with each other.
The Mote Marine Aquarium includes on its campus the largest marine wildlife rehabilitation center in the country. Further, it has seven associated centers for marine research. Sea World and the Florida Aquarium are great, but sometimes it's better to support the little guy, even if they are a not-for-profit.
The aquarium has various levels of membership, each of which allows a certain number of people to piggyback onto your membership. There's Duo ($50, unlimited free visits for you and a guest), Friend ($90, three guests), Sponsor ($125, five guests), Sustaining ($300, seven guests), Patron ($500, nine guests), and Benefactor ($1000, 11 guests). If you want to visit an aquarium that's more focused on integrity and education rather than flashiness and size, then look no further than Mote. Where else are you gonna see a real Giant Squid?
