Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 7.1 cm TL male/unsexed; (Ref. 101681)
Maximum length based from data in Tortugas, Florida, USA (Ref. 101681). Maximum depth from Ref. 79713. Found in the coast (Ref. 121706) and offshore (Ref. 106823); occasionally enters estuaries (Ref. 106823). On mouth of bays to 60 m, rarely observed to 420 m (Ref.79470). In the continental shelf, on fine and silty sand (Ref. 121706). Associated with muddy sediments; abundant in sediments with high amounts of silt and clay (Ref. 104233). Also occurs on organic debris and calcareous algae (Ref. 106549).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Spawns during spring and summer; continuous reproduction at lower latitudes, with increased seasonality of the breeding period at higher latitudes (Ref. 101677). Mating behavior: First contact, if the male was behind the female it immediately began to push under the female with its cephalothorax, but if from any other position, the male moved behind the female before pushing below it. The male then followed behind the female, it grasped or contacted the female's abdomen with its long antennal flagella, which quivered or vibrated during this "following" behavior. The dorsal cephalic region of the male, with the rostrum, eyes, and antennules, touched and prodded the female's genital area or thelycum, where the apertures to the female's seminal receptacles
are located. The male pushed upwards, tilting the female's body forward so that the genital region on the posteroventral cephalothorax was lifted well off the substratum. The male assumed the copulatory position by rolling upside down below the female, with the male's body perpendicular or slightly oblique to that of the female. In the copulatory position, the genital regions of the male and female were opposed. Copulation usually terminated when the male rolled back to an upright position and backed away slightly from the female, although the female sometimes broke off the copulation with sudden retrograde swimming by rapid abdominal flexion. After a copulation, the male frequently initiated following behavior again (Ref. 101680).
