ghost nets

Loose commercial fishing nets – called ghost nets – can weigh thousands of pounds and are estimated to make up 10% of all marine trash.

They collect everything in their path as they sink.

Indra's Net

Richard and Judith Lang used a ghost net to create their art exhibit, Indra's Net. The net represents how we're all interconnected. The promises on the net – like the jewels on Indra's Net in Hindu legend – hold our wishes, dreams and visions for a healthy ocean habitat for all marine life.

Read how our team of veterinarians and volunteers rescued and rehabilitated him before releasing him back into the wild. Read more

The Ghost Net Monster

Sperm whales dive to depths of 10,000 feet to feed. Sometimes, what seems like food isn't.

Richard and Judith Lang created The Ghost Net Monster sculpture from 450 pounds of ghost net pulled from the belly of a dead sperm whale. Watch their story.

never-ending cycle

When the net is freed of fish and debris, it rises again to the surface and repeats the cycle.

"This thing is rising and falling in the ocean, silently moving and capturing anything and everything."
