Nymphon Brevirostre
''Nymphon brevirostre'' is a species of sea spider first described by George Hodge in 1863. The species highly resembles other members of the genus ''Nymphon ''Nymphon'' is a genus of sea spiders in the family Nymphonidae. 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 fo ...'' (e.g. ''N. rubrum''), and species identification from morphological traits alone is therefore a complex task.King, P.E., 1974. British Sea Spiders. Synopses of the British Fauna (New Series), 5. Morphology Early life stage morphology White, translucent or reddish, occasionally with violet bands. Slender body (2.5-3.0 mm) and legs that are three and a half times as long. The proboscis is relatively short. The abdomen is thick, and the thoracic segments are broader than long. The palps have five joints. The propodus is longer than the tarsus, which is covered with numero ...

Sea Spider
Sea spiders are marine arthropods of the order Pantopoda ( ‘all feet’), belonging to the class Pycnogonida, hence they are also called pycnogonids (; named after ''Pycnogonum'', the type genus; with the suffix '). They are cosmopolitan, found in oceans around the world. The over 1,300 known species have legs ranging from to over . 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. Although "sea spiders" are not true spiders, or even arachnids, their traditional classification as chelicerates places them closer to true spiders than to other well-known arthropod groups, such as insects or crustaceans. This is in dispute, however, as genetic evidence suggests they may be the sister group to all other living arthropods. Description Sea spiders have long legs in contrast to a small body size. The number of walking legs is usually eight (four pairs), but the family Pycnogonidae hav ...

Nymphon
''Nymphon'' is a genus of sea spiders in the family Nymphonidae. 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. 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. This genus may also contain bioluminescent species. Distribution 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 speci ...
