Tardigrade phylogeny constructed from 18S rRNA. Phylogeny produced using maximum likelihood analyses under a GTR+I+Γ model using 884 bases of 18S rRNA. Numbers at nodes are support values generated from 1000 bootstrap pseudoreplicates. Terminal labels associated with unique numbers were identified as: Macro 001–008 – Macrobiotus furciger, Macro 048-52,68-077 – Macrobiotus sp. (hufelandi type), Dacty – Dactylobiotus sp., Acut – Acutuncus antarcticus, Diph – Diphascon sp., RamO – Ramazzottius oberhaeuseri, Isohyp – Isohypsibius asper, MilnT – Milnesium tardigradum, MilnC – Milnesium sp. "charcot", Bryod – Bryodelphax sp., EchinC – Echiniscus sp., EchinT – Echiniscus testudo.
