Their members feed by digesting copepods, and lack a canal system and choanocyte chambers.

Prey decomposition times strongly suggest the activity of extracellular enzymes, but there is currently no direct evidence for their involvement, or for their potential bacterial or poriferan origin.

Particles are subsequently phagocytosed and intracellularly digested by archaeocytes and so-called bacteriocytes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
