Ammotheidae is the most diversified group of the class
Pycnogonida
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, fou ...
, 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.
