我们最熟悉的软甲纲动物是 真虾总目 （Eucarida）十足目（Decapoda）的成员，特别是那些做熟后会变成鲜艳的橙红色，揭开头胸甲，里面是绵软滑嫩的膏和黄；剥去腹壳，露出紧致爽弹的白肉……的大中型种类。 囊虾总目虽然种类不少，但是体小（一般就是潮虫那么大，最大的是大王具足虫 Bathynomus giganteus），肉少，味道差，没什么经济价值，人们自然也就不屑一顾了。 十足目应该是和人们的生活关系最密切的节肢动物了。 人们脑海中“甲壳动物”的形象和认识，基本 …

2015年1月1日 · Syncarida (Figure 31.4) are mostly small to minute eumalacostracan crustaceans, closely related to Peracarida, that have cylindrical bodies and lack a carapace, and today are represented by fewer than 300 described species. They have an extensive fossil record of extinct forms from the Carboniferous, when they exhibited substantial diversity.

shellfish, any aquatic invertebrate animal having a shell and belonging to the phylum Mollusca, the class Crustacea (phylum Arthropoda), or the phylum Echinodermata. The term is often used for the edible species of the groups, especially those that are fished or raised commercially.

Syncarida are malacostracan crustaceans that live exclusively in fresh and brackish waters all over the world. With the exception of a few Anaspidacea that live in free freshwater (streams, ponds, superficial lakes and caves) the great majority inhabit the interstitial groundwater (they are stygobiont that live in groundwater in the wide sense).

Superorder Syncarida. The crustacean Superorder Syncarida is composed of only two, strictly-fresh (and brackish) water orders: Anaspidacea and Bathynellacea. Anaspidaceans are represented by 21 species (12 genera) in Australia and the Neotropics. The order is …

Syncarida is a superorder of typical crustaceans. There are 13 species of Syncarida, in 7 genera and 4 families. They rely on drag powered swimming to move around. Drag swimmers use a cyclic motion where they push water back in a power stroke, and return their limb forward in the return or recovery stroke.
