The graceful clam shrimp (Lynceus gracilicornis) is a species of clam shrimp found in Texas , northern Florida and possibly other regions in between.[1]
Characteristics
This large clam shrimp presents a body colouration varying from orange to rose, and a dark maroon shell; the eggs carried by the female are yellow to orange.[1] The species is distinguished from other Lynceidae members because the males have a pair of large claspers, with the right clasper being larger than the left. There are no growth marks on the carapace, as in other clam shrimp.[1] Graceful clam shrimp swim upside down or on their side, using legs and antennae for backward propulsion.[1]
Ecology
Lynceus gracilicornis is usually found in the shallow grassy parts of temporary ponds.[1] When oxygen levels are high, some individuals may be found in deep water. Graceful clam shrimp feed on plankton that they collect while swimming.[1]
Reproduction
The male clasps the lower margin of the female's shell and swims while holding her above him. Females carry up to 200 eggs under the carapace.[1]
