    Tubularia indivisa is a large hydroid reaching 10 to 15 cm in height. Living in small clumps, the unbranched stems, gathered at the base, are pale horn coloured and bear a single pale pink polyp. The tentacles form two concentric circles: those of the external circles are longer than those of the oral one.
    It lives attached to rocks, or sometimes among seaweeds' haptera in current-swept areas. Tubularia indivisa lives in the North-East Atlantic Ocean, the English Channel, the North Sea and the Norwegian Sea.

    Given that the presence of Tlx appears to be ubiquitous in bilaterians, Tlx was likely present in the last common ancestor of Bilateria and Cnidaria and then secondarily lost multiple times in cnidarians, including at the base of Anthozoa, Endocnidozoa and independently several times in Hydrozoa.
    Although no expression patterns were documented in reproductive medusa of Pelagia due to its large size, Tlx expression in the reproductive medusa of Podocoryna was found to be localized to the manubrium, both in cell populations distinct from the germline as well as in mature oocytes in the medusae.
