Lophophorate PhylaShelby Schmeltzle

Phylum Names and Examples of AnimalsLophophorate Phyla= Brachiopoda,

Phoronida, and BryozoaPhylum Brachiopoda- lampshells are solitary

marine animals that inhabit cold water.Northern lamp shells (Terebrauline septentrioalis)

Phylum Phoronida- Horseshoe wormsPhylum Bryozoa- “moss animals”,

Crawling yellymossanimal; Cristatella Mucedo

Northern Lamp Shells Horseshoe Worms

Crawling Yellymossanimal

CharacteristicsMarine animals adapted for life on the ocean

floor

Lophophore- a ciliated ring of tentacles that surround the mouth and is specialized for capturing suspended particles in the water.

Often asexual reproduction

U shaped gut

Body formsBrachiopods

Resemble clams and other bivalve mollusks because the body is enclosed between two shells

Differ because shells are dorsal and ventral instead of lateral.

Attach to substrate by a long stalkLophophore

Brachiopoda Phoronida

Body forms cont.Phoronids and Bryozoa

A “crown” of tentacles-lophophore build upright tubes of chitin to support and

protect their soft bodies.

FeedingCilia on the lophophore beat, this brings

water laden with food into the mouth or opening. This allows them to filter the food they need out of the water.

Secretion and Gas ExchangePhoronids secrete tubes of sediment and live

in them, extending their lophophores from their tubes for feeding

Nearly all secrete outer casings (shells, tubes, exoskeletons)

Bryozoa: gasses are exchanged through body surface, especially the tentacles

ReproductionBryozoa form sessile colonies by asexual

budding or by statoblast production. Statoblast- small seedlike structure

Reproduction in all lyphophorate phyla is often asexual reproduction.
