“…Thus, maternal care of this species under natural conditions probably lasts up to 10 days. This estimate matches observations by Lim and Alexander (1986). In C. scaura, the presence of the mother enhanced growth of the young, but was not effective for survival.…”

“…Second, the mother gathers her young and carries them to another place in cases of emergency. This is common behavior in C. decipiens, C. monoceros, and C. scaura (see Lim and Alexander, 1986;Aoki and Kikuchi, 1991). The two behavioral characteristics suggest communication between mother and young in maternal care caprellids.…”

“…In Caprella scaura typica Mayer, 1890(=C. scaura Templeton, 1836, young emerge from the brood pouch, cling onto their mother for about a week, and the mother takes care of them (Lim and Alexander, 1986). During ecological studies of caprellids in a bed of Sargassum (Aoki, 1988;Aoki and Kikuchi, 1990a;Edgar and Aoki, 1993), we found another maternal care species, Caprella mnnoceros Mayer, 1890, which showed behavior similar to C. scaura.…”

“…mitigation of physical stresses in the environment (Clutton-Brock, 1991). According to behavioral descriptions of maternal care in caprellid amphipods (Lim and Alexander, 1986;Aoki and Kikuchi, 1991), such care should not include providing food. Until now, however, no study has tested the ecological implications of maternal care in caprellids.…”

“…The former is the period of maternal care for eggs and the latter for juveniles. Moreover, in caprellid amphipods, prolonged cohabitation of mother and young emerged from her brood pouch have been observed in some species (Montagu, 1804;Harrison, 1940;Lim and Alexander, 1986;Aoki and Kikuchi, 1991).…”

Mother-young association was examined in 9 species of caprellid amphipods in the genus Caprella. Five species: Caprella arimotoi, C. danilevskii, C. glabra, C. okadai, and C. penantis showed no interaction between mother and young after emergence from her brood pouch, but various degrees of prolonged cohabitation of young with their mother were observed in the other four species. In Caprella subinermis, though no maternal care was observed, the first instars remained on the body of the mother for up to 4 days, and then dispersed before the first molt. Aggregations of young protected by the mother were observed in the other 3 species. Aggregations of a mother with multiple cohorts of young were found in Caprella decipiens, while C. monoceros and C. scaura had single cohorts of young on or around the body of the mother. Based on field data and results of field-rearing experiments, the cohabiting period is up to 30 days in C. decipiens and up to 20 days in C. monoceros. For 5 species having different degrees of mother-young association, one-month field-rearing experiments under predator-free conditions were conducted. The results showed that the presence of the mother increased both the survival and growth rate of the young in C. monoceros, but the presence of the mother increased only the growth rate in C. scaura. In the other 3 species, C. danilevskii, C. decipiens, and C. subinermis, the presence of the mother did not positively affect either survival or growth of the young.
