It’s official: The southern tidewater goby is a thing. And it’s chubbier and nubbier than its northern cousin.
Endangered tidewater gobies live in California’s seaside lagoons. Ranging roughly the entire length of the state, the fish used to be considered one species. But a new study confirms that gobies living in Northern and Southern California are physically different, and now the southern swimmer has its own name: Eucyclogobius kristinae.
