Larval development and follicle structure of a representative of the Calcinea (Calcispongiae) Guanchaarnesenae from the White Sea have been studied for the first time at the ultrastructural level. The follicle in G.arnesenae has an unusual structure: it consists of trapezoid cells rich in phagosomes and a surrounding dense collagen layer. Follicular cells differentiate from choanocytes. Cleavage results in formation of a hollow, equal, non-polarized coeloblastula. Larval morphogenesis occurs by… Expand

Embryogenesis and larval ultrastructure in Paraleucilla magna (Calcarea, Calcaronea), with remarks on the epilarval trophocyte epithelium (“placental membrane”)
TLDR
The embryogenesis and ultrastructure of the amphiblastula of Paraleucilla magna (Porifera, Calcaronea) is described and the possibility of cross-cells being precursors of the germ cell lineage and the vertical transmission of bacteria found in the larva are discussed. Expand
Some aspects of the oogenesis of three species of clathrinid sponges (Calcarea, Porifera)
  • E. Lanna, M. Klautau
  • Biology
  • Journal of the Marine Biological Association of the United Kingdom
  • 2015
TLDR
The phylogenetic character mapping analysis indicated that egg development in the mesohyl is the ancestral state for Calcinea, while the ancestral condition of the vitellogenesis is still uncertain. Expand
Kinetid structure in larval and adult stages of the demosponges Haliclona aquaeductus (Haplosclerida) and Halichondria panicea (Suberitida)
TLDR
Detailed structure of the flagellar apparatus (kinetid) in larval cells and choanocytes of Haliclona aquaeductus and Halichondria panicea demosponges is described and schemes of its organization are attached, based on longitudinal and transversal ultrathin serial sections. Expand
Kinetid in larval cells of Spongillida (Porifera: Demospongiae): tracing the ancestral traits
TLDR
It is suggested that spongillids retain the plesiomorphic characteristics of roots and an accessory centriole, but they possess the peculiarities of the transition zone, transverse cytoskeleton and MTOC structure. Expand
Oogenesis and spermatogenesis in Paraleucilla magna (Porifera, Calcarea)
TLDR
The gametogenesis of Paraleucilla magna (Porifera, Calcarea) is described using light and electron microscopy and shows a compact electron-dense nucleus and a homogeneous granulated body in its cytoplasm. Expand
Ultrastructure of the ciliated cells of the free‐swimming larva, and sessile stages, of the marine sponge Haliclona indistincta (Demospongiae: haplosclerida)
We provide a detailed, comparative study of the ciliated cells of the marine haplosclerid sponge Haliclona indistincta, in order to make data available for future phylogenetic comparisons at theExpand
Matrotrophy and placentation in invertebrates: a new paradigm
TLDR
It is reported that regardless of the degree of expression, matrotrophy is established or inferred in at least 21 of 34 animal phyla, significantly exceeding previous accounts and changing the old paradigm that these phenomena are infrequent among invertebrates. Expand
Integrative systematics of clathrinid sponges: morphological, reproductive and phylogenetic characterisation of a new species of Leucetta from Antarctica (Porifera, Calcarea, Calcinea) with notes on the occurrence of flagellated sperm
TLDR
Sperm is reported here for the first time in the whole Calcinea subclass and possess a typical spermatic mid-piece, which is usually observed in cnidarians. Expand
Some Like It Fat: Comparative Ultrastructure of the Embryo in Two Demosponges of the Genus Mycale (Order Poecilosclerida) from Antarctica and the Caribbean
TLDR
Compared the embryogenesis and yolk formation in two species inhabiting contrasting latitudinal areas: M. acerata from Antarctic waters and M. laevis from the Caribbean, the general morphological feature of embryos and larvae of both species were very similar, but the main difference resided in the yolk nature. Expand
Ectyoplasia ferox, an Experimentally Tractable Model for Vertical Microbial Transmission in Marine Sponges
TLDR
This work proposes E. ferox as a model system for vertical transmission owing to the ease of experimental access to all sexual reproductive stages, and to experimental tractability in the laboratory including the possibility of rearing symbiont-free juvenile sponges. Expand

Larval development in the Homoscleromorpha (Porifera, Demospongiae)
TLDR
The presence of a basement membrane and a true epithelium in the larva of Homoscleromorpha—unique among poriferan clades and shared with Eumetazoa—suggests that Demospongiae could be paraphyletic. Expand
Morphology and fine structure of the swimming larvae of Ircinia oros (Porifera, Demospongiae, Dictyoceratida)
TLDR
The fine structure of the free-swimming larvae of the sponge Ircinia oros from the northern Mediterranean was studied using light and electron microscopy to show that the study of sponge larvae is a source of diagnostic characters at the order level. Expand
Metamorphosis of Coeloblastula Performed by Multipotential Larval Flagellated Cells in the Calcareous Sponge Leucosolenia laxa
TLDR
Gl glutinous granules were found in these three principal cell types of juvenile sponges, thus indicating the multipotency of the flagellated cells of the coeloblastula. Expand
Larval development, ultrastructure and metamorphosis in Chondrilla australiensis Carter, 1873 (Demospongiae, Chondrosida, Chondrillidae)
TLDR
The cleavage, development and ultrastructure of larvae and settlers in the oviparous sponge Chondrilla australiensis are investigated, and the monophyly of order Chondrosida is confirmed. Expand
Metamorphosis of calcareous sponges II. Cell rearrangement and differentiation in metamorphosis
TLDR
Electron microscopic observations of metamorphosing larvae reveal the rearrangement and differentiation of larval cells as well as the cell lineage in the metamorphosis of the calcareous sponge. Expand
Metamorphosis of calcareous sponges I. Ultrastructure of free-swimming larvae
TLDR
Free-swimming larvae of two calcareous sponges were studied by electron microscopy and it is suggested but not concluded that the cruciform cells participate in photoreception. Expand
Metamorphosis of the larva of Halisarca dujardini (Demospongiae, Halisarcida)
TLDR
It is proposed that Oagellatcd cells of the larva and their derivatives are the main source of all rhagon structures. Expand
Flagellar basal apparatus and its utility in phylogenetic analyses of the porifera
TLDR
The flagellar basal apparatus of sponges is more similar to that found in choanoflagellates than it is to that observed in eumetazoans, and a robust similarity in structure of the basal appartus is observed among the three species of halichondrids studied to date. Expand
Embryogenesis and larval differentiation in sponges
TLDR
Original data on the mode of cleavage, timing of cellular differentiation, and the mechanisms involved in the organization of differentiated cells to form the metazoan body plan are reviewed. Expand
Ultrastructure of the oocyte and embryo of the calcified sponge,Petrobiona massiliana (Porifera, Calcarea)
TLDR
In the spongePetrobiona massiliana, a Calcarea related to “pharetronid” fossils, the oocyte and the embryo both receive an unusual amount of maternal nurse cells and the cruciform cells of the embryo appear to degenerate at an early stage. Expand
