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.
