Summary  Euryarchaea from the genus   H   alorhabdus  have been found in hypersaline habitats worldwide, yet are represented by only two isolates:   H   alorhabdus utahensis   AX ‐2 T  from the shallow  G reat  S alt  L ake of  U tah, and   H   alorhabdus tiamatea   SARL 4 B  T  from the  S haban deep‐sea hypersaline anoxic lake ( DHAL ) in the  R ed  S ea. We sequenced the   H   . tiamatea  genome to elucidate its niche adaptations. Among sequenced archaea,   H   . tiamatea  features the highest number of glycoside hydrolases, the majority of which were expressed in proteome experiments. Annotations and glycosidase activity measurements suggested an adaptation towards recalcitrant algal and plant‐derived hemicelluloses. Glycosidase activities were higher at 2% than at 0% or 5% oxygen, supporting a preference for low‐oxygen conditions. Likewise, proteomics indicated quinone‐mediated electron transport at 2% oxygen, but a notable stress response at 5% oxygen.   H   alorhabdus tiamatea  furthermore encodes proteins characteristic for thermophiles and light‐dependent enzymes (e.g. bacteriorhodopsin), suggesting that   H   . tiamatea  evolution was mostly not governed by a cold, dark, anoxic deep‐sea habitat. Using enrichment and metagenomics, we could demonstrate presence of similar glycoside hydrolase‐rich   H   alorhabdus  members in the  M editerranean  DHAL M edee, which supports that   H   alorhabdus  species can occupy a distinct niche as polysaccharide degraders in hypersaline environments.
