Almennt

Planispirinoides bucculentus (Brady, 1884)

Miliolina buculenta Brady, H.B. 1884, Report on the Foraminifera dredged by H.M.S. Challenger during the years 1973–1876, Zoology, v. 9, pp.170-171, pl. 114, fig.3. 

Description: Initial whorls closly coiled, in an equable spiral; later chambers are semi-globuluar, added in a spiral sequence of a single plane, perpendicular to the initial spiral tubular chamber; three semi-globular chambers are externally visible. Surface is smooth and polished; sutures are depressed and distinct. Aperture in globular chambers is an elongated, somewhat irregular slit with an apertural flap. Diameter of largest specimens nearly 5 mm but specimens around 2 mm are common.

Diagnosis. Relatively large specimens, with three successively larger semi-globular chabers added in a single plane.

Hæð stöpla svarar til fjölda sýna þar sem tegundin er: fágæt (1-2 eintök); sjaldgæf (3-8 eintök); alltíð (9-32 eintök); algeng (>32 eintök). Gögn úr botndýraverkefninu (Bioice). (ENGLISH- Column height represents number of samples in bins where the species is: rare (1-2 specimens); occasional (3-8 specimens); common (9-32 specimens); and abundant (>32 specimens.) Data from the Bioice programme.) – Ljósm. Guðmundur Guðmundsson

Dreifing tegundar eftir dýpi, seltu og sjávarhita, innan þess breytileika sem allar sýnatökustöðvar ná yfir, sýnt sem heildarspönn lóðréttra ása. Gögn úr botndýraverkefninu „BIOICE“. (ENGLISH – Occurrence zone of the species within the range of water depth, temperature, and salinity, spanned by the "Bioice" samples; demarcated by respective y-axes.) – Ljósm.
