Classification:
Kingdom: Animalia
Phylum: Arthropoda
Class: Branchiopoda
Order: Ctenopoda
Family: Sididae
Description:
The organism exhibits an almost oblong carapace, featuring a rectangular posterodorsal corner. The posteroventral corner is adorned with a series of small denticles, typically numbering between 12 to 20, followed by small setae. The dorsal margin is more arched compared to the almost straight or slightly ascending ventral margin. The shell duplicature is broad on the distal end. Its head is well-defined, relatively narrow, lacking a rostrum, and slightly tapers distally, with an almost obliquely truncated frontal end. The eye is notably large and positioned near the anterior margin of the head. Its antennae are short, not extending to the hind edge of the carapace. The postabdomen is narrow, with setae on the lateral side and lacking anal spines. Claws feature three basal spines. In terms of reproduction, it utilizes parthenogenesis. The parthenogenetic female progresses through a series of adult instars and produces batches of eggs. Instead of being released into the exterior environment, the eggs are incubated within the brood pouch of the mother. Embryonic development takes place within the brood pouch, and the offspring are eventually released as juveniles.
