incudate

The incudate trophi of Asplanchna are massive forceps quite free from an inclosing mastax, and capable in consequence of even plunging down into the oesophagus; but the forcipate trophi of Sacculus are feeble hooks and blades, inclosed in a grape-shaped mastax, and admitting of only a slight protrusion from the mouth.

FIGURE 140.[…]A-E with a malleate mastax in the Brachionidae and a malleo-ramate in the Flosculariaceae, mainly feed by sedimenting; F and G with virgate or incudate mastax, respectively, are more selective and raptorial.

Asplanchna priodonta (Asplanchnidae) is a planktonic predator with incudate trophi, showing a wide trophic spectrum, feeding on rotifers, protists, and various unicellular algae (Jose de Paggi, 2002).

In Asplanchnidae, rami are large and hooked and constitute incudate mastax, but reduced rami may be present.
