    HOW CAN I MATE WITHOUT AN APPENDIX MASCULINA? THE CASE OF SPHAEROMA TEREBRANS BATE, 1866 (ISOPODA, SPHAEROMATIDAE) BY GIUSEPPE MESSANA1) CNR-Istituto per lo Studio degli Ecosistemi, Via Madonna del Piano, I-50019 Sesto Fiorentino, Firenze, Italy ABSTRACT Several hours mating behaviour of the woodborer isopod, Sphaeroma terebrans were recorded using a video camera. S. terebrans, the only species in the genus to lack an appendix masculina, has a peculiar way of mating that is completely different from that in other Isopoda. Instead of introducing the sperm into the genital opening of the female, the male releases it into the water current created by the beating of the female pleopods. The origin of this adaptation is discussed. RIASSUNTO Il comportamento sessuale dell’isopode Sphaeroma terebrans, è stato filmato per diverse ore, attraverso una telecamera. S. terebrans, l’unica specie del genere ad essere sprovvista di una appendix masculina, ha un modo di accoppiarsi del tutto particolare che è completamente differente da quello degli altri isopodi. Il maschio invece di introdurre lo sperma nella apertura genitale femminile, lo rilascia nella corrente d’acqua creata dal battito dei pleopodi. L’origine di questo adattamento viene discussa. INTRODUCTION Isopods colonize almost every environment on earth, from deep seas to desert mountains. Their long evolutionary history, the first fossil dating from the Car- boniferous (Schram, 1986), has led to great morphological variety. Despite such a wide diversity of morphotypes, the species share a common character: a copula- tory organ, constituted by a modified endopod of the male pleopod II (Brusca & Wilson, 1991). The appendix masculina (= male stylet) is used to transfer sperm to the female during mating.

  • Basal Position of Two New Complete Mitochondrial Genomes of Parasitic
    Hua et al. Parasites & Vectors (2018) 11:628 https://doi.org/10.1186/s13071-018-3162-4 RESEARCH Open Access Basal position of two new complete mitochondrial genomes of parasitic Cymothoida (Crustacea: Isopoda) challenges the monophyly of the suborder and phylogeny of the entire order Cong J. Hua1,2, Wen X. Li1, Dong Zhang1,2, Hong Zou1, Ming Li1, Ivan Jakovlić3, Shan G. Wu1 and Gui T. Wang1,2* Abstract Background: Isopoda is a highly diverse order of crustaceans with more than 10,300 species, many of which are parasitic. Taxonomy and phylogeny within the order, especially those of the suborder Cymothoida Wägele, 1989, are still debated. Mitochondrial (mt) genomes are a useful tool for phylogenetic studies, but their availability for isopods is very limited. To explore these phylogenetic controversies on the mt genomic level and study the mt genome evolution in Isopoda, we sequenced mt genomes of two parasitic isopods, Tachaea chinensis Thielemann, 1910 and Ichthyoxenos japonensis Richardson, 1913, belonging to the suborder Cymothoida, and conducted comparative and phylogenetic mt genomic analyses across Isopoda. Results: The complete mt genomes of T. chinensis and I. japonensis were 14,616 bp and 15,440 bp in size, respectively, with the A+T content higher than in other isopods (72.7 and 72.8%, respectively). Both genomes code for 13 protein-coding genes, 21 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and possess a control region (CR). Both are missing a gene from the complete tRNA set: T. chinensis lacks trnS1 and I. japonensis lacks trnI. Both possess unique gene orders among isopods.

  • Juvenile Sphaeroma Quadridentatum Invading Female-Oœspring Groups of Sphaeroma Terebrans
    Journal of Natural History, 2000, 34, 737–745 Juvenile Sphaeroma quadridentatum invading female-oŒspring groups of Sphaeroma terebrans MARTIN THIEL1 Smithsonian Marine Station, 5612 Old Dixie Highway, Fort Pierce, Fla 34946, USA (Accepted: 6 April 1999) Female isopods Sphaeroma terebrans Bate 1866 are known to host their oŒspring in family burrows in aerial roots of the red mangrove Rhizophora mangle. During a study on the reproductive biology of S. terebrans in the Indian River Lagoon, Florida, USA, juvenile S. quadridentatum were found in family burrows of S. terebrans. Between September 1997 and August 1998, each month at least one female S. terebrans was found with juvenile S. quadridentatum in its burrow. The percentage of S. terebrans family burrows that contained juvenile S. quadridenta- tum was high during fall 1997, decreased during the winter, and reached high values again in late spring/early summer 1998, corresponding with the percentage of parental female S. terebrans (i.e. hosting their own juveniles). Most juvenile S. quadridentatum were found with parental female S. terebrans, but a few were also found with reproductive females that were not hosting their own oŒspring. Non-reproductive S. terebrans (single males, subadults, non-reproductivefemales) were never found with S. quadridentatum in their burrows. The numbers of S. quadridentatum found in burrows of S. terebrans ranged between one and eight individuals per burrow. No signi® cant correlation between the number of juvenile S. quadridentatum and the numbers of juvenile S. terebrans in a family burrow existed. However, burrows with high numbers of juvenile S. quadridentatum often contained relatively few juvenile S.

The biodiversity associated with cultivated mussel assemblages depends partly on the source of the mussels and on the new habitat created by the method of cultivation. To date, no study has been made of the macrofauna associated with mussels in the habitats created by different methods of mussel cultivation in the Black Sea.

A marine isopod, S. laevidorsalis must be submerged in water to breathe. S. laevidorsalis grows to about 3 cm in length and can be found on docks and pilings among seaweed and hydroids. This isopod is classified as an omnivorous scavenger, eating both dead and living material, particularly hydroids. The camouflage pattern on its body allows it to blend in with its environment, and the tiny claws on each leg help it cling to surfaces.
