Unusual scaled preservation samples on freshwater decapods (Crustacea, Decapoda) from the Pleistocene (Late Cenozoic) of Turkey and Kazakistan

We report two rare examples of preservation by calcareous incrustation of two specimens of decapod crustaceans, discovered in continental carbonate deposits from the Pleistocene (Late Cenozoic) of SW Turkey (W Anatolia) and S Kazakistan (“Caucasian Area”) respectively. The specimen from Turkey is assigned to <em>Potamon</em> Savigny, 1816 (Potamidae) while the specimen from Kazakistan is assigned to <em>Austropotamobius</em> Skorikov, 1907 (Astacidae).

Freshwater Decapods

Direct physical evidence for predation upon decapod crustaceans is extremely limited in the fossil record. Although it is well recognized that decapods serve as a food resource for a wide variety of vertebrate and invertebrate predators and that the remains of decapods, in the forms of molts and corpses, are readily scavenged, direct evidence for these activities is limited (Tshudy et al., 1989). Bishop (1975) summarized evidences for predation in the fossil record and, although he frequently referred to decapods as predators, cited only one example (Bishop, 1972) of the group as prey. Thus, the discovery of three specimens of freshwater decapods, referable to the crayfish family Cambaridae, that clearly exhibit the effects of predation is significant.

Scanning Electron

Sperm of decapod crustaceans are formed by a round or cup-shaped body, a complex acrosome and one a few appendages emerging from the main body. Although this sperm does not have motility, it has some components of the cytoskeleton like microtubules, which are found inside the appendages. Actin filaments have been found in the spike of penaeidae sperms. The actual participation of the crustacean decapod sperm cytoskeleton during fertilization is not well understood. Actin is supposed to play an active role in drawing the penaeidae shrimp sperm closer to the egg after bending of the spike. The present study was aimed at the localization of actin filaments in sperm of the Robinson Crusoe island lobster, Jasus frontalis and in the crayfish Orconectes propincus, by fluorescent probes and low voltage scanning electron microscopy.
