SIMRbase Organisms
The worm anemone has an elongated column measuring up to 14 cm in length and 12 mm in diameter. The tentacles are relatively stout, very long and up to 16 in number. Tentacles are transparent becoming strongly tinted with brown in the outer half, spotted with opaque white or cream, the spots becoming larger towards the tips where they tend to form transverse bars. The disc is pale buff or cream, with a well-defined pattern of rich, often purplish-brown. 
Smed flatworms are bilaterally symmetric, triploblastic animals that possess a wide variety of differentiated cell types and organ systems. Smed are stable diploids that exist as two biotypes: asexual animals that reproduce by fission, and obligate cross-fertilizing hermaphrodites that reproduce sexually (Newmark and Sánchez Alvarado, 2002; Newmark et al., 2008). Smed embryos are direct developers: newborn hatchlings grow and mature into adult worms without an intervening larval stage (Sánchez Alvarado, 2003). At hatching, juveniles are sexually immature but otherwise possess a body plan grossly similar to the adult hermaphrodite (Sánchez ... 
Western Brook Lamprey (Lampetra richardsoni): Many lamprey species have a prolonged larval period, after which they metamorphose into a parasitic adult phase that attaches to and feeds on various fish species. The Western brook lamprey is a freshwater resident species that has evolved to forgo the parasitic lifestyle and instead spawn shortly after metamorphosis. Most species that have lost a parasitic stage have close relatives (or “paired species”) that are parasitic. In the case of the Western brook lamprey, this is the Western river lamprey (Lampetra ayresii). Thus far the Western brook lamprey is the only nonparasitic specie... 
Pacific lamprey (Entosphenus tridentatus): The Pacific lamprey is an anadromous parasitic lamprey species native to the West Coast of North America. The species is an important cultural food resource to the Columbia River Treaty Tribes of the U.S. Pacific Northwest and has been since time immemorial. The Columbia River discharges to the Pacific Ocean, is the largest river of the Pacific Northwest region of North America occupying a basin size of 258,000 square miles, and is the center of abundance of Pacific lamprey. The genome was sequenced in part to support ongoing conservation efforts of the species which has been heavily impacte... 
SIMRbase Genome
Welcome Public
SIMRbase is the place for assembled genomes and genome related data at the Stowers Institute for Medical Research. Here you can find tools to search sequences with BLAST, keywords, GO terms, tools to browse genomes, and tools to manually curate gene models. Currently SIMRbase has public access to Petromyzon marinus, the sea lamprey and its germline genome assembly, Nothobranchius furzeri, African killifish or turquoise killifish, Scolanthus callimorphus, the worm anemone, and Nematostella vectensis the starlet sea anemone. For more information or to get help contact Sofia Robb (simrbase@stowers.org).
