About Deep Sea World
Deep Sea World is a significant aquarium located in the village of North Queensferry, Fife, Scotland. Established on April 9, 1993, it occupies the site of the former Battery Quarry, situated beneath the iconic Forth Rail Bridge. The aquarium is operated by the Spanish Aspro Ocio Group, which also manages other aquariums across Europe.
Key Features and Exhibits
A primary highlight of Deep Sea World is its extensive underwater viewing tunnel, measuring 112 meters (367 ft) in length. This transparent acrylic structure is recognized as one of the longest of its kind worldwide. The 6.5-centimeter (2.6 in) thick acrylic walls create a de-magnifying visual effect, reducing the perceived size of the aquatic inhabitants by approximately one-third. The main exhibition tank holds 1,000,000 imperial gallons (4,500,000 l; 1,200,000 US gal) of seawater drawn from the River Forth. The water temperature typically hovers around 14 °C (57 °F) and fluctuates seasonally. Due to this cooler temperature, many of the animals displayed in the tunnel are native to British waters, which helps reduce their metabolic rates.
The aquarium also showcases a variety of other tanks and rock pools featuring exotic fish and marine life. In 2005, a dedicated seal enclosure was added, serving as a home for resident seals and providing refuge for injured seals rescued by the Scottish Society for the Prevention of Cruelty to Animals (SSPCA).
