A common dolphinarium design for public performances consists of stands for the public around a semi-circular pool, sometimes with glass walls which allow underwater viewing, and a platform in the middle from which the trainers direct and present the show.
Though animal welfare has improved significantly over the last few decades, many animal rights and welfare groups such as the WSPA still consider keeping dolphins at dolphinariums a form of animal abuse. The lifespan of dolphins in captivity is another subject of debate.
