“…It has been demonstrated that egg size is correlated with both the duration of embryogenesis and the size of hatchlings (Steele and Steele 1975;Wehrtmann and López 2003). Regarding thalassinideans, the available information demonstrate that species with an abbreviated larval development such as Callianassa kraussi (Forbes 1973), C. tyrrhena (Thessalou et al 1999) and L. sinuensis (Nates et al 1997) produce larger eggs than those with extended larval development (C. filholi: 0.68 mm, Berkenbusch and Rowden 2000). According to Aste and Retamal (1983), the larval development of C. seilacheri consists of five larval stages; thus our egg volume data confirm that relatively small eggs indicate a prolonged larval period.…”

“…It is a useful indicator of the duration of embryogenesis and larval size at hatching (Steele and Steele 1975). Moreover, several studies on thalassinidean shrimps showed a clear relation between egg size and type of larval development (Forbes 1973;Felder and Griffis 1994;Thessalou et al 1999). Such information, however, is restricted to just a few thalassinidean species.…”

Egg production of the burrowing shrimp Callichirus seilacheri (Bott 1955) (Decapoda, Callianassidae) in northern Chile

The thalassinidean shrimp Callichirus seilacheri is a common species in the intertidal zone of the South American Pacific coast. However, our knowledge of its reproductive ecology is rather limited. The present study was carried out between January and December 2003 at Las Machas, northern Chile. Although ovigerous females were encountered almost throughout the study period, they were particularly abundant between May and September when water temperatures were lowest and sediment coverage of the burrow entrances was highest. Females of C. seilacheri produced numerous (17,450 ± 3,796 eggs) and small (0.884 ± 0.080 mm; 0.262 ± 0.054 mm 3 ) eggs when compared to other thalassinidean shrimps for which such information is available. Fecundity was positively correlated with female size; however, correlations were allometric, which might be related to the elasticity of the abdomen. Egg volume increased by 41.2% during embryogenesis, and egg loss during the incubation period was on average 8%. Females inverted on average 14.9% of their dry weight into egg production.

Thalassinidean shrimp construct species-specific burrows which vary in morphology from simple 'U' or 'Y' shaped tubes to more complex tiers of galleries or reticulate branches. Data on the burrow architecture of 44 species in 10 genera indicates that the morphological patterns of thalassinidean burrows are more diverse than previously recognized. Based on a review of these data and the existing information on thalassinidean feeding, we propose several generalizations in the form of a heuristic model relating burrow architecture and trophic mode in these fossorial decapods. Despite moderate levels of morphological variation between species, thalassinidean burrows can be categorized into 6 major groups based on their morphological characteristics The 6 burrow types are distinguishable based on the presence or absence of (1) surface sediment mounds at excurrent openings, (2) seagrasses in chambers or the burrow lining, and (3) a simple 'U' shaped burrow design. Although relatively little is known about the functional significance of the different architectural patterns, each burrow type may be indicative of one of the 3 general trophic modes utilized by burrowing shrimp: (1) deposit feeding, (2) drift catching, and (3) filter/suspension feeding. Two different types of burrows are discernible within the mound-producing, deposit-feeding group, 3 distinct burrow morphotypes are associated with filter/suspension feeding, and the 6th burrow morphotype is produced by the drift catchers. The ecological significance of these 6 burrow types is discussed in addition to the effects of various environmental parameters on mtraspecific variation in burrow morphology.

This investigation explored the effect of the heavy metals Pb (Pb 2+ ) and Zn (Zn 2+ ) individually and in combination (i.e. three metal solutions) on both the brood and larval development of the burrowing crustacean, Callianassa kraussi. Egg and larval mortalities at factorial (4x7) combinations of salinity (20, 24, 30, 35 mg/l) and seven respective metal concentrations were examined. The results provided various statistically significant trends. Individual concentrations of Pb and Zn at various salinities impacted negatively upon the brood and larval development of Callianassa kraussi. Increasing the specific concentrations of both metals further demonstrated a negative influence, especially on brood development and to a lesser extent on larval development of Callianassa kraussi. Comparing the toxicity of the three concentrations of metals to Callianassa kraussi brood and larval development, it was found that individual Pb concentrations exhibited the least mortality (LC 50 Pb-eggs-35ppm = 1.580 mg·l -1 whilst individual Zn concentrations displayed considerably higher mortality (LC 50 Zn-eggs-35ppm =0.066 mg/l) but that the combination of Zn and Pb concentrations produced the highest mortality =0.036 mg·l -1). Varying salinities in permutation with varying metal concentrations exhibited a significant detrimental influence on the brood and larval development of Callianassa kraussi, notably at the lowest salinities in combination with the highest metal concentrations.
