Eugastrozoa

## Taxonomy

Anthostoma

Gastrozoa

**Eugastrozoa**

The **Eugastrozoa** (lit. "true Gastrozoans") are a clade of Gastrozoa.

## Decription

Eugastrozoans, like early anthostomes, are sessile and radially symmetrical animals. However, their tentacles are adapted to more actively ensnare prey from the water rather than passively strain it. They also possess a larger feeding cavity, granting them comparatively greater feeding efficiency.

Their free-floating nymph stage is sexless, while their sessile form is hermaphroditic.

### Larvae

Eugastrozoa larvae, while still considered zooplankton, grow up to several centimeters in length before maturing. As a result, they fill a similar role to jellyfish, hunting smaller zooplankton such as Tachypods or smaller Anthostome larvae.

Eugastrozoan larvae themselves are prey to nektonic filter feeders, such as Ptilopods or Isopterygians.
