Fairy Shrimp

Eubranchipus bundyi

Ancient crustaceans that hatch in Michigan's vernal pools each spring and vanish weeks later. No genome exists for any of the 21 species in this genus. We intend to sequence the first.

Paused

This project is on hold while we coordinate with the Michigan Natural Features Inventory on vernal pool access and specimen collection protocols. Vernal pool habitats are ecologically sensitive and we want to do this right.

Project paused pending MNFI coordination

Vernal pools are ecologically sensitive habitat. Pausing collection efforts until we hear back from MNFI on appropriate protocols and partnership opportunities.

Milestone
Mar 2026

Confirmed: zero Eubranchipus genomes exist worldwide

NCBI search confirms no nuclear genome assembly for any of the 21 species in the genus. Only mitochondrial genomes for two Japanese species.

Vernal Pool Field Collection

Pending coordination with MNFI and the Vernal Pool Patrol. Once partnerships are established, we'll organize community collection events at appropriate sites.

Why fairy shrimp matter

Fairy shrimp are among the oldest living lineages of crustaceans, largely unchanged for hundreds of millions of years. They survive in one of the most unpredictable habitats on Earth — temporary pools that form in spring and vanish by summer. Their eggs, called cysts, can remain dormant in dried mud for years or even decades.

Michigan is home to at least two species: Eubranchipus bundyi (the knobbed-lip fairy shrimp, common and widespread) and E. neglectus (less common). They are ecological indicators of healthy vernal pool habitat — pools that also support breeding salamanders, frogs, and invertebrate communities.

Despite their ecological importance, fairy shrimp are genomically invisible. A reference genome would open the door to population genetics, conservation genomics, and evolutionary biology across the entire genus.
