Tidewater Goby
Tidewater Gobies are endangered fish found only in California, living in the calm, brackish waters of lagoons, salt marshes, and eelgrass beds. Pollution and coastal development have pushed them toward extinction. Marsh restoration is helping populations bounce back. 100% of profits from these sustainable greeting cards support San Francisco Baykeeper, a local nonprofit partner using science, advocacy, and the law to defend the Bay.

Meet the Artist
Anna Costanza
🏡 Habitat: San Francisco, CA (Richmond District)
🐠 Fun Fact: My favorite job was working on a boat in San Francisco Bay teaching kids about the wonders of plankton, fish, and mud critters.
🚲 Hobbies: Long bike rides, running in the fog, dancing, thrifting for lamps, making soup for friends, floating in the ocean and of course, making art.
About Anna's artwork on the card:
The inspiration for my painting is the shallow waters of eelgrass beds of San Francisco Bay and the special habitat they provide to many species, one being the tidewater goby. I am drawn to nature’s organized chaos, playing with perspectives, and depicting smallness in big worlds.
"I believe art is the most powerful tool in growing human appreciation, awe, and awareness to the natural world. The CACC project is very wholesome, effective, and unique with a clear mission and impressive impact. I care deeply about being connected and connecting folks to the beauty and value of local and far away environments, especially those more nuanced or underappreciated, arguably the salt marsh as an example. As a previous M.S. student in Interdisciplinary Marine Sciences, and time working at a Marine Science educator, I have an intimate understanding of the bay area salt marshes and the important protection they serve our bayside communities, large avian populations, and nursery species in the early stages of life. I think this project is both clever, cool, (yes I said cool!) and meaningful work."

Tidewater Goby
Eucyclogobius newberryi
🏡 Habitat: Coastal lagoons, estuaries, eelgrass beds, and salt marshes along California’s coastline
🌱 Fun Facts: I am a tiny (2 inches long), fierce protector of my burrow and eggs!
🦐 Hobbies: Digging cozy burrows in soft sediment, weaving through swaying eelgrass (pictured in my greeting card), snacking on tiny crustaceans, and guarding my territory in calm, brackish water.
"Hey there! I’m the Tidewater Goby — a small but mighty fish found only in California! In 1994 I was listed as endangered. I make my home where freshwater streams meet the sea, in salt marshes, lagoons, and eelgrass beds that teem with life. These habitats protect the coast, filter pollution, and provide nurseries for countless species. But pollution, coastal development, and wetland loss have destroyed much of my habitat, leaving many of us isolated in small pockets along the shore. Thanks to restoration efforts, eelgrass and salt marshes are slowly returning, which help us, too! Every healthy wetland brings new hope for the future of California’s coasts (and little fish like me)."
Meet SF Baykeeper
our nonprofit partner
🏡 Habitat: San Francisco Bay
🛥️ Fun Fact: I'm the only organization that regularly patrols the San Francisco Bay, by boat and by air, to investigate pollution.
🌎 Hobbies: We love to restore the wetlands, patrol the waters, and even take polluters to court—keeping the Bay clean and safe for fish, birds, and people alike!
"For 36 years we've patrolled the Bay, stood up to polluters, and defended the Bay and local communities from major threats. The Bay faces unprecedented threats from the federal government and corporate polluters. We’re holding them accountable—People and wildlife deserve to thrive. We use science, advocacy, and law to hold polluters accountable and stop destructive activities throughout the Bay and its watershed."
DID YOU KNOW? San Francisco Baykeeper has been taking legal action against the City of San Francisco for releasing millions of gallons of mixed sewage and stormwater into the Bay, especially during heavy rains when the city's combined system becomes overwhelmed. Recent legal developments include the Supreme Court siding with San Francisco in a dispute that could weaken the Clean Water Act, and a joint lawsuit against the city by the EPA, California, and Baykeeper to force system upgrades. Baykeeper also points to outdated infrastructure as a major cause and encourages public action to minimize pollution.
