Nymphon is a genus of sea spiders in the family Nymphonidae. [1] [2] The species of sea spiders within the genus Nymphon are all benthic organisms and are found in abyssal and bathyal areas of the ocean. This is a fully marine group and can be found at various depths ranging from the littoral zones to the deep sea. They are found in most major oceans across the globe with a strong distribution around polar regions: Arctic and Antarctic waters. [3] Out of the sea spider genus, Nymphon is the most rich, with a majority of the species within the genis being found in the Southern Ocean region. [4] This genus may also contain bioluminescent species. [5]
Sea spiders in general are found all around the globe. The Nymphon genus has been commonly found in waters of higher latitudes and is associated with polar regions and having a more circumpolar distribution than other genus of sea spider. They are extremely abundant within polar regions, with Nymphon having the most species found in polar waters. [6] In relation to the benthos, mainly inhabit marine fauna and are often found around sessile communities. [7]
Generally, it is thought that Nymphon feed on hydroids, actinians, bryozoans, molluscs, annelids, crustaceans, and detritus. They have strong associations with corals and algae. However, feeding behavior in relation to coral and algae has not been observed and there is no current evidence of finding coral or algae material in their gut. [8]

Sea spiders are marine arthropods of the order Pantopoda, belonging to the class Pycnogonida, hence they are also called pycnogonids. They are cosmopolitan, found in oceans around the world. The over 1,300 known species have leg spans ranging from 1 mm (0.04 in) to over 70 cm (2.3 ft). Most are toward the smaller end of this range in relatively shallow depths; however, they can grow to be quite large in Antarctic and deep waters.
Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Colossendeidae is a family of sea spider. Like most sea spiders, species in this family have four pairs of legs, except for three species with five leg pairs, including the first polymerous sea spider discovered, and one giant species that was the first sea spider discovered with six leg pairs.
Hedgpethia is a genus of sea spider, in the family Colossendeidae. The genus was named after the marine biologist and sea spider specialist Joel Hedgpeth.
Nymphonidae is a family of sea spiders which has representatives in all the oceans. This family contains some 250 species, most of which are found in the genus Nymphon. Nymphonid bodies are between 1 and 15 mm long, the extent between the points of the legs reaching 150 mm. Most species are predators of hydroids. Like most sea spiders, species in this family have four pairs of legs, except for Pentanymphon antarcticum, which has five pairs, and Sexanymphon mirabilis, which has six pairs.
Thurles Sarsfields is a Tipperary GAA club which is located in County Tipperary, Ireland. Both hurling and Gaelic football are played in the "Mid-Tipperary" divisional competitions. The club is centred in the town of Thurles at Semple Stadium. The club was founded in 1881 and is the most honoured club in the history of the county championship with 36 County Titles.
Cyclaspis is a genus of cumacean crustaceans in the subfamily Bodotriinae, containing the following species:
Pycnogonum is a genus of sea spiders in the family Pycnogonidae. It is the type genus of the family.
Ammotheidae is the most diversified group of the class Pycnogonida, with 297 species described in more than 20 genera, of which only Nymphopsis and Sericosura were found to be monophyletic. Despite its internal taxonomic uncertainty, studies on 18S rRNA supports its monophyly, and the subdivision on Achelinae and Ammotheinae subfamilies.
Achelia is a genus of pycnogonids in the family Ammotheidae.
Tanystylum is a genus of pycnogonids in the family Ammotheidae.
Colossendeis is a genus of sea spider belonging to the family Colossendeidae.
Callipallene is a genus of sea spiders in the family Callipallenidae. There are more than 30 described species in Callipallene.
Phoxichilidium is a genus of sea spiders within the family Phoxichilidiidae. Members of this genus can be found in all oceans at depths up to 1074 meters.
