Note the inverted commas, pincer-like, around the title. In this episode, we discuss 'crabs' - the various animals that end up under the 'crab' umbrella. Tom chats 'crabs' with Mark Losavio, diver, eduactor and marine biologist. We talk all things crab, and also discuss working in aquariums, teaching children about the ocean, and Mark shares his perspective on being a black man in marine science.
