“…Thus, based on this, the species described by Mello-Leitão should be moved to the genus Ceriantheomorphe . Carlgren (1931) mentions that the species (with this name) as described by him in that publication may be a junior synonym of C. brasiliensis Mello-Leitão 1919 , as Lopes et al (2019) have shown. Hertwig (1882) recorded a specimen of Cerianthus americanus from the Uruguayan coast whose external shape appeared to be very similar to that of Ceriantheomorphe brasiliensis .…”

“…A very large species, which for many years was considered to be synonymous with C. brasiliensis even without biogeographic justification. Recently, Lopes et al (2019) have indicated morphological differences that support the distinction between both species. Apparently, this is a species with very low incidence, since several sampling attempts have been unsuccessful (S. Stampar pers.…”

The diversity of Ceriantharia is known from studies formally describing species from the late 18th Century onwards. However, no nomenclators including a list and discussion of all valid species have been produced since a list discussed by Carlgren in 1912. The present nomenclator presents a complete list of adult species of Ceriantharia of the World, including a discussion on each species. It includes the three families (Arachnactidae, Botrucnidiferidae, Cerianthidae) and the currently accepted 54 species based on their adult form. This study serves as a presentation of the “state-of-the-art” list of species of Ceriantharia, and includes a species identification key to support taxonomic identification. Additional in-depth species-by-species investigations for almost all cerianthid species is still needed, as the information available for most of these species is quite superficial.

“…Ceriantharians are morphologically distinguishable from other anthozoans by synthetizing a type of cnida, the ptychocyst, a unique feature of the group ( Mariscal, 1974 ). Tube-dwelling anemones exhibit two ranks of external and internal tentacles, the marginal and labial tentacles respectively ( Carlgren, 1912 ), and pores may occur throughout this structure ( ØVan Beneden, 1924 ; Lopes et al, 2019 ). The organization of mesenteric filaments is also different in Ceriantharia, the trilobed shape of the filaments is uncertain; and new mesenteries emerge from the multiplication chamber ( Stampar et al., 2016 ).…”

Background Ceriantharia is a subclass of the phylum Cnidaria, which comprises tube-dwelling marine invertebrates. This subclass is composed of three families, including Arachnactidae, with two known genera. Currently, the genus Arachnanthus has five valid species recorded from Australia, the Mediterranean Sea and both the Southern and Northern Pacific Ocean. However, at the moment, there is no record of organisms of this family from the South Atlantic Ocean. Besides that, the life cycle of any species of the genus Arachnanthus is known. The present study describes a new species of the genus Arachnanthus and its life cycle, based on specimens from Uruguay and South of Brazil. Methods Larvae were collected by plankton net in Rio Grande—Brazil and the development and external morphology of these specimens were observed in the laboratory during two years, and subsequently described. Additionally, nine adult ceriantharians correspondent to the larvae from Rio Grande were collected in Uruguay and their external and internal anatomies, and cnidome were described. Results Arachnanthus errans sp. nov. exhibited a free-swimming, short-lived cerinula larvae that spent short-time on the plankton. The larva developed into small and translucent polyps with a short actinopharynx, one pair of mesenteries attached to a siphonoglyph, and a medium first pair of metamesenteries. Further, the adult polyp displayed an unprecedented locomotion behavior in Ceriantharia that is first reported here, it can crawl under and in between the sediment.
