Sea Pens: Not the Panacea They Are Perceived.

"Numa" the first purposed acquired captive killer whale being moved in the sea-pen in 1966.

Perhaps one of the most irksome comments that come from the animal-rights community and self-styled marine mammals expert is that of the use of sea pens.   

This has again been muted with the fanciful idea that 'Lolita' -  the killer whale at Miami's Seaquarium - will be given over to animal-rights activists to be moved to a proposed but yet unbuilt sea pen in Washington State - due to her possible listing as an 'endangered' species.
