Entoprocta

Entoprocta (Gr. entos inside + proktos anus) is          Entoprocts
a phylum of small aquatic animals, ranging in     Scientific classification
size from 0.5 mm to 5.0 mm. They have a
lophophore, and as their name suggests, are      Kingdom: Animalia
distinguished from other lophophorates by the    Phylum:  Entoprocta
position of the anus inside the ring of cilia
rather than outside. Other names include goblet           Families
worm and kamptozoan.                             Barentsiidae (Urnatellidae)
                                                 Loxokalypodidae
Entoprocts are filter feeders, their tentacles   Loxosomatidae
secreting a mucus that catches food particles,   Pedicellinidae
which is then moved towards the mouth by cilia
on the tentacles. Nearly all species are sedentary, attached to the
substrate by a stalk, with the body being cup-shaped. Some species are
colonial, with multiple animals on branching systems of stalks.

Entoprocts can reproduce either by budding, or sexually. They are unusual in
being sequential hermaphrodites.

The phylum includes about 150 species in several families. While most
species are marine, the freshwater species Urnatella gracilis is widespread.
