| Summary: | Species Tjalfiella aff. tristoma (2022) Fig. 5, 6, 12 Material— Nine samples of T. aff. tristoma collected by the ROV Deep Discoverer on the NOAA Okeanos Explorer and stored in the Smithsonian National Museum of Natural History (EX2205_D05_04B_A03; USNM-IZ-1674065). Additional pictures of living specimens observed during the same dive were used for morphological analyses and host availability. Description Body— Benthic ctenophore, compressed in the stomodeal plane, “U” shaped in the tentacular plane; two extendable aboral arms that lack oral grooves on opposing sides of body; distal ends of arms are flattened with a malleable outer margin that is capable of folding inwards, contains two openings, a singular gastric accessory opening, and a single smaller tentacular opening; overall body surface is smooth with no warts or visible papillae, exceptions are two to four pairs of globular gonads on the aboral face (number of gonads vary between individuals). Size— 5mm in height, 7.6mm in tentacular length, 3mm in ... : Published as part of Bezio, Nicholas & Collins, Allen G., 2024, Redescription of the deep-sea benthic ctenophore genus Tjalfiella from the North Atlantic (Class Tentaculata, Order Platyctenida, Family Tjalfiellidae), pp. 241-266 in Zootaxa 5486 (2) on page 261, DOI: 10.11646/zootaxa.5486.2.4, http://zenodo.org/record/13209847 ... |
