“…All major groups of freshwater Decapoda, the atyid and palaemonid shrimps, aeglid anomurans, crayfish, and freshwater crabs, have some reproductive traits in common, namely, the reduction of egg number compared to their marine relatives, the increase of egg size accompanied by extensive deposition of yolk, and the tendency to abbreviate larval development (Jalihal et al, 1993;Bond-Buckup et al, 1996;Sternberg et al, 1999;Shy et al, 2001;Reynolds, 2002). These features are interpreted as specific adaptations to riverine habitats or even as a preadaptation to the colonization of freshwater (Scholtz, 2002).…”

Prolonged brood care is one of the evolutionary clues for the successful colonization of freshwater habitats by freshwater crayfish (Astacida). By means of macrophotography, light microscopy, and scanning electron microscopy we investigated all phases of brood care in freshwater crayfish, with particular emphasis on the morphological structures involved. We selected the recently discovered parthenogenetic marbled crayfish (species identity not yet known) as a model organism due to its fast reproduction and high resistance to handling stress. In order to examine if there is a causal relationship between brood care and the developmental status of the offspring's sensory apparatus, we additionally investigated major sense organs of juvenile Stages 1-5 in comparison with those of the adults. Brood care in the marbled crayfish is characterized by initial and final "active" phases dominated by specific maternal or juvenile behavior and a medial "passive" phase based more on the action of temporarily developed structures rather than on behavior. The most remarkable feature of this period, which includes permanent carrying of the eggs and the first two juvenile stages under the mother's abdomen, is safeguarding of hatching by a telson thread that keeps the helpless newborn hatchlings linked to the egg cases on the maternal pleopods and thus prevents them from being lost. Further important transient structures are the recurved hooks on the first pereiopods of Stage 1 and 2 juveniles that are used to firmly attach these nonfeeding stages to the mother's abdomen. In hatchlings all sense organs necessary for an independent life, such as eyes, olfactory aesthetascs, gustatory fringed setae, hydrodynamic receptor hairs, and statocysts are not developed or are underdeveloped, making brood care indispensable. Most of these sense organs appear in Stage 2 juveniles, but only from Stage 3, the first freelancing and feeding stage, are all sense organs well developed and operating, thus reducing brood care in this final period to temporary provisioning of shelter. Brooding of the eggs and postembryonic brood care are to some extent also found in other freshwater Decapoda like freshwater crabs and aeglid anomurans, but safeguarding of hatching is confined to the Astacida only. This sophisticated mode of passive brood care is unique in the animal kingdom and is apparently related to the sensory deficiencies of the first juvenile stage.

“…The large ova are similar in size to the ova of C. formosae Hung, Chan & Yu, 1993 (ova 1.04 × 0.68 mm), a species with highly suppressed, larval development and an almost fully formed, benthic hatchling (Shy et al 2001).…”

Caridina biyiga sp. nov. is described from Leichhardt Springs, Kakadu National Park, Northern Territory, Australia, based on morphological and molecular data. The new species is highly distinctive among its congeners in having the dactylus of pereiopod 5 similar to the dactyli of pereiopods 3–4 and lacking the comb-like row of spiniform setae typical of the genus. The branchial formula is also distinctive for the genus in lacking an arthrobranch at the base of pereiopod 1 and in having a vestigial epipod on maxilliped 1. Despite the distinctive morphology of the new species, the molecular data did not provide strong support for the recognition of a new genus. Phylogenetic analyses of Australian Caridina using the mitochondrial 16S rDNA gene fragment placed the new species in a well-supported clade containing at least one typical species of Caridina. Within this clade, referred to as the ‘thermophila’ group, Kimura 2-parameter (K2P) genetic distances of 16S rDNA between the new species and sister taxa ranged from 5.1–6.0%. Analyses using the mitochondrial 3’ COI gene fragment from species of the ‘thermophila’ group yielded K2P genetic distances between the new species and its sister taxa ranging from 10.4–15.1%. A preliminary illustrated key to Northern Territory Caridina is provided. The conservation significance of Leichhardt Springs and its aquatic fauna are also briefly discussed.

“…All of the materials used for identification and eggs measurement were kept in the Laboratory of Animal Biosystematic and Evolution, Department of Biology, Faculty of Sciences, Tadulako University, Palu, Indonesia. The eggs size of ovigerous females were measured from the longest and shortest axis [11] using a digital caliper (0.2 mm). Water temperature measurement was made using a mercury thermometer.…”

Notes on the distribution of Caridina sulawesi, an endemic freshwater shrimp from Sulawesi, Indonesia

Caridina sulawesi Cai and Ng, 2009, an endemic freshwater shrimp, has been described based on the type locality in Maros, South Sulawesi. Surprisingly, this species was reported from two rivers in Central Sulawesi. Here, we provided the data about ecological aspects and the recent distribution of the species on Sulawesi Island. The specimens were collected using a hand net in 2018 and 2019, from a small natural spring in Bobo and two creeks in Napu. Water temperature varied between 17 to 22°C. Our finding shows C. sulawesi inhabited almost all freshwater habitat exclude lake system, with high variation in elevation and water temperatures.
