Bryozoa anatomy.

Bryozoans make excellent model colonial animals. Their life histories range from ephemeral to perennial.

The colonies usually have a skeleton of calcium carbonate. Bryozoans have a long fossil history, starting in the Ordovician. In their life-style they resemble the polyps which form coral. Bryozoa are known informally as moss animals or sea mats. The spine is the backbone of the human skeleton. It is made up of 24 bones known as vertebrae, according to Spine Universe. The spine provides support to hold the head and body up straight. It is also flexible enough to prevent injury and a...

Identification: Pectinatella magnifica is a species of freshwater bryozoan in the class Phylactolaemata. Like other species of bryozoans (also known as Ectoprocta or commonly as moss animals), the individual microscopic aquatic invertebrates (called a zooid) live directly on submerged surfaces in a colony (Ricciardi and Reiswig 1994, Wood 2010).Study with Quizlet and memorize flashcards containing terms like Nematomorphora, Nematomorphorma characteristics, Nematomorphora Reproduction and more.

They have mineralized exoskeletons and form single-layered sheets which encrust over surfaces, and some colonies can creep very slowly by using spiny defensive zooids as legs. Each zooid consists of a "cystid", which provides the body wall and produces the exoskeleton, and a "polypide", which holds the organs.View full document. Students also studiedPhylum Bryozoa.

A Anatomy and Physiology. A bryozoan colony is composed of identical linked animal units ( zooids ). An individual zooid consists of a partially protrusible organ system (= polypide) surrounded by a body wall. The polypide bears a large retractable lophophore with cilated tentacles used to collect food.

Their skeletons have many tiny openings. Each opening is the home of zooid. They have a body with a U-shaped gut, opening at the mouth and at the anus. They feed with their lophophore. The tentacles of the bryozoans are ciliated. The beating of the cilia creates a current of water which drives food (mainly phyto plankton) towards the mouth.
