Egg size and clutch size in three species of Nihonotrypaea (Decapoda: Thalassinidea: Callianassidae) from western Kyushu, Japan

Abstract: Three species of the callianassid genus Nihonotrypaea occur in the Ariake Sound estuarine system, southern Japan; they consist of two tidal-flat species (N. harmandi; N. japonica) and one boulder-beach species (N. petalura), with maximum population densities of 1440, 343, and 12 ind m−2, respectively. Nihonotrypaea harmandi and N. petalura are distributed along the coastline from the outermost part of the sound to the open sea, while N. japonica occurs in the middle part of the sound. Nihonotrypaea japonica ha… Show more

“…This supports by greater than 5º in latitude which is similar to the degree of separation between the sites sampled by Rotherham and West (2009) and the sites sampled in the current study. Kubo et al (2006) also found a latitudinal gradient in the size of ghost shrimps (Nihonotrypaea japonica and N. harmandi) embryos, again with the smaller embryos at higher latitude. summarised literature that showed that food availability may be a driving factor of latitudinal differences in embryo size.…”

“…summarised literature that showed that food availability may be a driving factor of latitudinal differences in embryo size. In contrast, Kubo et al (2006) attributed latitudinal differences in embryo size to differences in temperature. For example, the higher the latitude the cooler the water and therefore the larger the embryo size [as seen for N. japonica (cooler waters) and N. harmandi (warmer waters)] (Kubo et al, 2006).…”
