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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Propallene Longiceps
''Propallene longiceps'' is a species of sea spider in the family Callipallenidae. It is found in shallow water in the western Pacific Ocean. Description ''Propallene longiceps'' has a compact body, the male being slightly more slender than the female. The propodus of the claw is slightly curved and has a number of elongate spines on its heel, and both males and females have hairy legs. The female is distinguishable by the swollen femurs of the walking legs, and the male is notable for the high number of cement gland ducts present, which is usually more than ten. Distribution ''Propallene longiceps'' is native to the tropical Indo-Pacific region. Its range extends from the Red Sea and the Horn of Africa to India, Malaysia, southern China and Japan. Biology In Pycnogonids, the female lays the eggs onto her walking legs, and in most species, the male transfers the eggs to his s (legs adapted for the care of eggs and young), where he fertilises them. This arrangement ensures that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
