“…Sponges of the Netherlands were the subject of a number of scientific studies in the recent past: van reporting 15 marine species; Buizer & van Soest (1977) reassigning a previously reported species to a species new to science. This was later on done also for a species previously identified as Prosuberites epiphytum (Lamarck, 1814), which was found to be an obligate Australian epiphyte of algae.…”

Continuous monitoring by scientists and volunteers of the Biological Working Group of the Dutch SubAqua Union and the ‘Anemoon’ Foundation over the past four years, yielded a surprising six new records of sponges for Dutch coastal waters. Oscarella lobularis, Celtodoryx girardae, Suberites virgultosus, Haliclona (Haliclona) simulans, Halisarca aff. dujardini, and a species identified as Leucosolenia somesii were unknown from Dutch coastal waters before 2000. The latter is a giant calcareous sponge, seemingly belonging to the common Leucosolenia variabilis, but here assumed to be an invader as well, as it has spicular characters well outside the variation found in the majority of Dutch L. variabilis specimens. It is likely a member of a ‘forgotten’ species, L. somesii. Habit photographs, SEM images of the spicules, and for O. lobularis and H. aff. dujardini, photographs of histological sections are provided to substantiate these new records. With the exception of C. girardae, most of the species resemble previously described widespread north-east Atlantic species, occurring in the area to the south and west of the Netherlands, so it is assumed pending future genetic research that at least several of the invaders comprise range extensions related to rising winter temperatures. Possibly, recent shellfish imports may be an additional causal agent. We also report the occurrence of unprecedented spicular deviations observed in three sponge species commonly occurring in Dutch waters, Halichondria (Halichondria) panicea, Hymeniacidon perlevis and Haliclona (Soestella) xena, which grew in small inland water bodies. Possibly, the limited space in these inland waters with possible stress factors for sponges such as reduced water exchange, and deviating chemistry, have caused the sponges to form stunted growth in spicules varying from rhabds with rounded endings to silica spheroids. We provide an updated list of sponges found in Dutch waters and a list of suspected or proven invaders of Dutch waters.

“…Material described below and all other collected specimens (together belonging to approximately 100 species) have been equally divided between three institutions: the Zoologisch Museum Amsterdam (ZMA), the British Museum (Natural History) London (BMNH), and the Zoologisk Museum K(Ilbenhavn (ZMUC), where they have been incorporated in their respective sponge collections. Methods employed in dealing with the specimens are the same as described in BUiZER & VAN SOEST (1977).…”

“…Section and spicule mounts for light microscopic study were made according to methods described by Riitzler (1978). SEM preparations of spicules were made as described by Buizer & Van Soest (1977). "In toto" SEM preparations were treated with 20% HNOj for 3-12 h, after which they were coated with a thin layer of gold.…”

Various records of A. simplex Carter, 1879 from the Atlantic are assigned to three new species of the sponge genus Asteropus Sollas, 1888, viz.: A. brasiliensis sp. n., A. vasiformis sp. n., and A. niger sp. n., whereas A. simplex s.s. is restricted to the Indo-Pacific. A worldwide study of Asteropus specimens resulted in the conclusion that two species groups exist, namely “simplex ”- like species (with true sanidasters), and “sarasinorum”- like species (with spiny microrhabds), as previously observed by Bergquist (1965, 1968). A newly discovered microsclere complement of trichodragmata in the first group strengthens the need for generic distinction of both lineages, and accordingly the name Melophlus Thiele, 1899 is reinstated for the “sarasinorum” species group. A key to the West Atlantic species of Asteropus is provided. The family allocation of Asteropus and associated genera in the Coppatiidae Topsent, 1898 is discussed, with the conclusion that the family is undoubtedly a polyphyletic assemblage related to various astrophorid groups (Hooper, 1986; Van Soest, 1991).
