Tardibase — The Tardigrade Genomics Knowledgebase

Alba Tull

A dedicated tardigrade genomics database tracking species, genome assemblies, stress tolerance genes, and sequencing runs across all known tardigrade species. Part of the ExtremoDex extremophile ecosystem.

What makes Tardibase unique

While ExtremoDex catalogs all extremophile organisms as dex cards, Tardibase goes deep on tardigrades — tracking individual genome assemblies, T2T completion status, stress tolerance genes like Dsup, CAHS, and SAHS, species-level taxonomy with cryptobiosis types, and all associated sequencing runs from NCBI SRA and ENA.

Tardigrade Stress Tolerance Genes

Tardigrades possess unique molecular adaptations for surviving extreme conditions. These genes encode proteins that protect DNA (Dsup), vitrify cytoplasm (CAHS), shield extracellular structures (SAHS), and defend against oxidative damage. Many are tardigrade-unique — not found in any other animal lineage.
