Constructed in 1972 The Water Mammal Exhibit displayed bottle-nosed dolphins.
A Review of Dolphinaria states:
Pools: A: roughly boomerang-shaped outdoor pool; max. length 19.0 m, max. width 5.0 m, 3.4 m deep. B: trapezium-shaped indoor pool; max. length 13.0 m, max. width 5.0 m, 3.4 m deep. C: rectangular indoor isolation pool with stranding shelf; 6.0 x 4.8 m; shelf 4.8 m x 2.0 m x 1.0 m deep, rest 2.5 m deep. Surface areas approx. 95, 65, 20 m2 ; total 180 m2 All pools can be operated and drained separately. Partly indoor, salt mix water.The Society has always exhibited a wide range of species and in the early 1970's it was decided that a representative of the Order Cetacea would enhance the educational value of their collection. A small unit was opened in May 1972, after extensive consultations with other establishments to determine the requirements for 'best practice' of the day. It was intended to be the beginning of a complex showing members of the Order (Manton, 1974), but no further development of the exhibit had been carried out by the end of 1985.
Photos were taken in 2008 with the exhibit now housing sea lions.
