Through an ethnographic analysis of an obscure commodity-the Maine sea cucumber-I explore entrepreneurship as a practice, rather than a set of attitudes. The sea cucumber trade creates a transnational network that reaches from rural Honduran villages, to Maine, to Asia. Many participants in this network might be called "entrepreneurs." I address two key questions: What do entrepreneurs do? And, how is entrepreneurship different from other forms of capitalist activity? I locate the source of entrepreneurial agency at the systemic level, challenging the hagiographic view of the individual entrepreneur as a dynamic source of economic growth.
