Aquarium where you walk through transparent tunnels underwater. It's small compared to Istanbul Aquarium in Yeşilköy, an hour will be plenty, and their combi-tickets with Madame Tussauds (in Beyoğlu) and Legoland indicate their target audience.
The TurkuaZoo also called Sealife is a public aquarium located in Bayrampaşa in Istanbul, Turkey. It was the first public aquarium in Turkey, and is one of the largest aquariums in Europe. In addition to being a major tourist attraction for Istanbul, the aquarium is a centre for marine research and conservation.

Hava Kuvvetleri Müzesi
A military-based museum with various warplanes, helicopters, and weapons used by Turkish Air Force, and also civilian air transport and examples of Turkish aeronautics from Ottoman era onward.
formerly San Stefano or Ayastefanos
A mostly upscale suburb on the coast of the Sea of Marmara, just south of the former airport. It was a multicultural village during the Ottoman period — the legacy of which still lives on in numerous churches of different Christian denominations dotting its streets — and later a seaside resort. Town centre has colourful wooden houses with highly decorative exteriors from the turn of the 20th century, especially around the railway station (itself a historic building) and the main street leading to it (which has many restaurants and cafes.) One mansion was where the Treaty of San Stefano was signed in 1878, ending the war with Russia — the frontline had extended this close to Constantinople. Town's main sights are the Aviation Museum and Istanbul Aquarium (not related to Sea Life). Get here on the Marmaray. Traffic in Yeşilköy is often congested, and parking is very hard to find.
An Olympic venue. Home court of the national team.
Much bigger aquarium than Sea Life, with over 1,500 species. 3 cafes and large parking lot.
