Why giant clams are at the center of our work
- Every species is threatened
- All giant clam species are threatened, and many reefs have lost theirs to overharvesting.
- They build habitat for the reef
- Giant clams provide habitat structure, contribute to nutrient cycling, and support reef calcification. Each clam is a microhabitat of its own.
- They carry the algae corals lose
- Giant clams host zooxanthellae, the same symbiotic algae bleached corals have lost. That link drives our coral research.
- They filter the water around them
- We're exploring giant clams as natural filters for microplastics.
- They can be grown out and returned
- We grow clams out in our mariculture tanks to reseed reefs where wild populations have declined.
Programs built around open questions
Can giant clams help bleached corals recover?
Testing whether zooxanthellae from giant clams can speed the recovery of bleached corals.
Micronesia, SpainTurning giant clams into carbon sinks
Testing whether raising seawater pH above 8.5 tips clam shell formation from carbon neutral to a true carbon sink.
JapanGiant clams as microplastic filters
Exploring clams as natural filters for microplastics, and growing them out to reseed reefs.
JapanMangrove conservation
Evaluating mangrove conservation for its carbon sequestration potential and biodiversity impacts.
BelizeThe first captive-reared carpet anemones
We've spawned S. haddoni in captivity and are working to rear the larvae to juveniles.
JapanRearing flowerpot coral
Rearing Goniopora for conservation and potential medical research.
JapanA clownfish genomic study
An ongoing genomic study of our breeding pairs and their offspring.

Giant clams, corals, and carbon
Carbon sinks Japan
Under natural conditions, giant clam shell formation is roughly carbon neutral, because CO₂ released during calcification offsets carbon uptake. We're testing whether raising seawater pH to levels typical of reef flats (8.5 or higher) can tip that balance and turn clams into true carbon sinks.
Microplastic filtration and reef reseeding Japan
We're exploring giant clams as natural filters for microplastics, and growing clams out in our mariculture tanks to reseed them onto reefs.
Coral bleaching recovery Micronesia, Spain
Using samples collected in Micronesia and our University of Barcelona lab, we're testing whether zooxanthellae from giant clams can improve the thermal tolerance of corals and speed the recovery of bleached corals.
Mangrove conservation in Belize
Mangroves sequester at least five times more carbon than tropical forests. They're also hotspots for biodiversity and key enablers of coral reef health, with many reef species using mangrove root systems as nurseries.
We're evaluating ongoing mangrove conservation activities in Belize, with specific attention to their carbon sequestration potential and biodiversity impacts.
Red, black, white, and buttonwood mangroves
Captive breeding and rearing in Japan
Clownfish
Our breeding pairs anchor school visits and our free classroom curriculum, and an ongoing genomic study of the pairs and their offspring. Every pair we breed takes pressure off wild collection.
Carpet anemone, S. haddoni
Nearly every one in the aquarium trade is wild collected. We've spawned it in captivity and are working on settling the larvae and rearing them to juveniles, which to our knowledge hasn't been documented.
Flowerpot coral, Goniopora
Among the most heavily traded corals and one of the hardest to keep. G. columna alone made up about 7.2 million pieces, 18 percent of the coral trade, from 2010 to 2020 under CITES records.

Stewardship, not passive preservation
We practice stewardship, not pure preservation: wise use, not passive protection. People are part of the natural world, not separate from it, and ecosystems intended to be protected in isolation are still shaped by everything happening around them.
When a species is farmed and used sustainably, it gains an economic reason to exist, funding for its recovery, and less pressure on wild populations.
