In home aquaria, size constraints mean that only the smallest sharks are typically viable as pets. ==Public aquaria== Until recently only a few benthic species of shark, such as hornsharks, leopard sharks, catsharks, and zebra sharks, had survived in aquarium conditions for up to a year or more. This gave rise to the belief that sharks, as well as being difficult to capture and transport, were difficult to care for. A better knowledge of sharks has led to more species (including the large pelagic sharks) being able to be kept for far longer. At the same time, transportation techniques have improved and long distance movement of sharks is becoming easier.〔(【引用サイトリンク】 title= Whale Sharks in Captivity )〕 One shark that never had been successfully held in captivity for long was the great white. But in September 2004 the Monterey Bay Aquarium successfully kept a young female great white shark for 198 days before releasing her back into the wild. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sharks in captivity」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
