Branchiopoda

[‚braŋ·kē′äp·ə·də]
(invertebrate zoology)
A subclass of crustaceans containing small or moderate-sized animals commonly called fairy shrimps, clam shrimps, and water fleas.

Branchiopoda

 

a subclass of the class Crustacea. The head is not fused with the front thoracic segments. There is no mandibular palp, and both the maxilla and mandible are weakly developed. The thoracic limbs are foliate and nonsegmented as a rule; they are used for locomotion, breathing, and bringing food to the mouth. The nerve stems of the ventral nerve cord are widely spaced. There are from four to 11 (rarely as many as 19) thoracic segments. The cephalothoracic carapace is shaped like a shield or a bivalve shell or is entirely absent. The animals live mainly in fresh water. The subclass comprises three orders: Anostraca, Phyllopoda, and Lipostraca (represented only by extinct forms).

And I realized that this brain actually comprises three successive neuropils in the optic regions, which is a trait of malacostracans, not branchiopods," he said.
The brain was also composed of three fused segments, whereas in branchiopods only two segments are fused.
In branchiopods, there are always only two visual neuropils and they are not linked by crossing fibers.
As a group, branchiopods are united by the presence of gills on their legs and various appendages used for swimming.
All the shrimp-like branchiopods feed themselves by filtering algae and detritus out of the water.
These days, branchiopods fare best in pools that periodically dry up, making it harder for those predatory aquatic insects to get established.
Indeed, generations of branchiopods never have to leave the pool at all, which means they've got the home-court advantage.
The occurrence of large branchiopod crustaceans in perennial pans: a research note.
After the first subsequent rains, the invertebrate fauna in these particular pans consisted of many "typical" temporary pan invertebrates, including various large branchiopods like: Anostraca (Fairy shrimp), Conchostraca (Clam shrimp), and Notostraca (Tadpole shrimp).
