Maintaining the line of defense: regeneration of Cuvierian tubules in the sea cucumber Holothuria forskali (Echinodermata, Holothuroidea).
Cuvierian tubules constitute a very efficient defensive mechanism: their large number, sparing use, and particular regeneration dynamics make them an almost inexhaustible line of defense maintained at limited energy cost.
Cuvierian tubules of the holothuroid Holothuria forskali (Echinodermata): a morphofunctional study
Quiescent Cuvierian tubules of Holothuria forskali have a pseudostratified mesothelium made of ciliated cells that cover elongated cells containing lipoproteie granules that is suggested that slippage of collagen fibers in elongating tubules is nervously mediated.
Focus stacking: Comparing commercial top-end set-ups with a semi-automatic low budget approach. A possible solution for mass digitization of type specimens
The system is inexpensive compared to high-end commercial focus stacking solutions, composed of commercial photographic equipment and enables institutions to purchase multiple solutions or to start digitising the type collection on a large scale even with a small budget.
A revision of Antarctic and some Indo-Pacific apodid sea cucumbers (Echinodermata: Holothuroidea: Apodida)
A revision of Antarctic and some Indo-Pacific apodid sea cucumbers (Echinodermata: Holothuroidea: Apodida) and some Taeniogyrinae species is provided.
Review of the millipede family Haplodesmidae Cook, 1895, with descriptions of some new or poorly-known species (Diplopoda, Polydesmida)
Th e polydesmoid family Haplodesmidae Cook, 1895 is reviewed and shown to be a senior subjective synonym of the family DoratodesmidAE Cook, 1896, which encompasses six genera and 30 recognizable species, all keyed here, including the following six new species: Eutrichodesmus basalis sp.
Review of the millipede genus Eutrichodesmus Silvestri, 1910 (Diplopoda, Polydesmida, Haplodesmidae), with descriptions of new species
Eutrichodesmus, the largest genus in the Oriental family Haplodesmidae, is reviewed and shown to encompass 24 recognizable species, all keyed, including the following nine new species: E. regularis
Sea cucumbers of the Comoros Archipelago
Sea cucumbers have been harvested for centuries in the Far East. Overexploitation, coupled with increasing demand has led to local depletion of certain standing stocks. De novo investigation at
A first phylogenetic analysis of Giant Pill‐Millipedes (Diplopoda: Sphaerotheriida), a new model Gondwanan taxon, with special emphasis on island gigantism
The current phylogeny of Giant Pill‐Millipede families mirrors perfectly the suggested break‐up of Gondwana fragments 160–90 Ma, and no evidence for a dispersal event could be found, highlighting the importance of Giantpill‐millipedes as a potential model taxon.
The asteroid fauna (Echinodermata) of Singapore, with a distribution table and an illustrated identification to the species
Twenty-seven species of asteroids have been collected over the period 1991-1995 by dredging, SCUBA-diving, and hand-collecting in the territorial waters of Singapore. They include fourteen species
