“To the dolphin alone, nature has given that which the best philosophers seek: friendship for no advantage. Though it has no need of help from any man, it is a genial friend to all and has helped mankind.”  –Plutarch
While the benign behavior by cetaceans towards humans hasn't changed since the philosopher Plutarch penned those words nearly two thousand years ago, the oceans have changed dramatically and cetaceans now need our help as never before.
When they come up on our shores - whether entangled, sick, lost, injured, or confused by navigational errors - our impulse is to help them get back into the water, or to send them for rehabilitation.
Rescuers are faced with daunting choices:

Return to the sea


Rehabilitation and release

"Rehabilitation of stranded marine mammals elicits polarized attitudes: initially done alongside display collections, but release of rehabilitated animals has become more common.

  • Justifications include animal welfare, management of beach use conflict, research, conservation, and public education.

  • Rehabilitation cost and risks have been identified that vary in degree supported by data rather than perception.

  • These include conflict with fisheries for resources, ignorance of recipient population ecology, poor understanding of long-term survival, support of the genetically not-sofit, introduction of novel or antibiotic-resistant pathogens, harm to human health, and cost.

  • Thus facilities must balance their welfare appeal against public education, habitat restoration, human impact reduction, and other conservation activities.

  • Benefits to rehabilitating marine mammals are the opportunity to support the welfare of disabled animals and to publish good science and so advance our understanding of wild populations.

  • In specific cases, the status of a population may make conservation the main reason for rehabilitation.

  • These three reasons for rehabilitation lead to contrasting, and sometimes conflicting, management needs.


We therefore outline a decision tree for rehabilitation managers using criteria for each management decision, based on welfare, logistics, conservation, research, and funding to define limits on the number of animals released to the wild."

Some rescued cetaceans are unable to be released and remain in captivity
