Do anti cruelty laws affecting animal care cover marine mammals?

In most jurisdictions yes, marine mammals are covered under anti-cruelty laws. For example, the United States' Animal Welfare Act (AWA) specifically lists marine mammals as animals covered under the law, and the act's regulations include specific standards for the care and handling of marine mammals in captivity. Similar laws exist in many other countries.

However, it's important to note that the specific details and scope of anti-cruelty laws can vary between jurisdictions, so it's always a good idea to consult with local animal welfare authorities or legal professionals for the most up-to-date information.
