The Scolicia burrows are interpreted as being inhabited by spatangoid echinoids (Scolicia; Fig.
Larval growth and perimetamorphosis in the echinoid Echinocardiwv cordalum (Echinoder-mata): the spatangoid way to become a sea urchin.
Unfortunately, there is no other local spatangoid available with which to compare Brisaster larvae.
latifrons was similar to descriptions by MacBride (1914), Fenaux (1961, 1969, 1972), and Rees (1953) for other, obligate-feeding spatangoid larvae, and by Runnstrom (1929) for larvae of B.
This might be more problematic for larvae settling on hard substrata and in high-energy environments such as the wave-swept intertidal habitat of Stomopneustes and less problematic for spatangoid larvae settling in soft-sediment habitats.
To do this, we will reconstruct the phylogenetic pattern of relationships for the spatangoid sea urchin Echinocardium, and explore, through shape analysis, the evolutionary processes involved in the differentiation of the species within the genus.
Numerous gregarines indeed parasitize holothuroids and spatangoid echinoids, with 22 known species, including D.
a sexually dimorphic amphiurid brittle star (Echinodermata: Ophiuroidea), epizoic on a spatangoid sea urchin.
Thus, glycine-rich repeat structure remains a common trait of the bindin of the Echinoida, although, as the data from the spatangoid Moira indicate, it is not a characteristic limited to this order or even to a closely aligned clade.
jacobyi lowers the center of mass, presumably facilitating upright orientation (Pennington and Strathmann, 1990; Young, 1995), but this is a feature also found in shallow-water spatangoid larvae (Mortensen, 1921).
The aims of the article are to give (1) an overview of the true direct development of this brood-protecting spatangoid that is endemic to the Kerguelen Islands (South Indian Ocean, 70 [degrees] 12 [minutes] E, 49 [degrees] 21 [minutes] S) and (2) preliminary evidence for a new mode of gastrulation.
