Shape and Symmetry of Brachiopoda: Brachiopoda are marine animals with a large lophophore consisting of a pair of coiled or folded arms bearing ciliated tentacles. The animal is enclosed in a bivalved shell. So they are commonly known as ‘Lamp shells’. The name Brachiopoda was coined by Dumeril (1806) (brachion-arm, podos-foot).P. S.

The Branchiopoda are separated as a distinct class of Crustacea based primarily on the form of the larvae, which eclose as a nauplius or metanauplius. The larvae have reduced, undifferentiated first antennae, the second antennae are elongated and used for swimming, and the mandible is uniramous.Branchiopod, any of the roughly 800 species of the class Branchiopoda (subphylum Crustacea, phylum Arthropoda). They are aquatic animals that include brine shrimp, fairy shrimp, tadpole shrimp, water fleas, and other small, chiefly freshwater forms. Branchiopods are generally regarded as primitive. P. S.

Palaeoecol. 317–318, 134–152 (2012). Fossils from this deposit are found in chips and nodules of silica thought to have precipitated from a silica saturated hot spring or geyser pool. If the habitat that these silica fossils were formed in was indeed a hot spring, it is not surprising that Lepidocaris rhyniensis is the only animal that is abundant in the deposit. Brachiopod Habitat Preference and Mode of Life All articulate brachiopods are sessile, benthonic suspension filter feeders. The inarticulate forms are rare and are either attached sessile, benthonic suspension filter feeders, or like the modern genus Lingula, live in holes bored into the bottom muds (Figure 3).Branchiopod, any of the roughly 800 species of the class Branchiopoda (subphylum Crustacea, phylum Arthropoda).
