Brachiopods , phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two … See moreIRMNG (2021). Glyptoglossella Cooper, 1960 †.

Brachiopods are a phylum of small marine shellfish, sometimes called lampshells. They are not common today, but in the Palaeozoic they were one of the most common types. They lived near the shore ( littoral zone ), but now they have been pushed into deeper water by competition from bivalve molluscs .Lamp shells, any member of the phylum Brachiopoda, a group of bottom-dwelling marine invertebrates. They are covered by two valves, or shells; one valve covers the dorsal, or top, side; the other covers the ventral, or …Correct option is C) Trematoda is a class within the phylum Platyhelminthes. It is a flatworm which is triploblastic in nature. These are acoelomate and has flame cells for excretion. These are parasitic in nature. So, the correct answer is option C. Was this answer helpful?

The structural organisation in all the brachiopods is more or less similar except the articulation of two shell valves. Here Magellania has been described as a typical example of the phylum Brachiopoda. 2. Habit and Habitat of Brachiopoda: Magellania is a marine and benthonic animal like all other brachiopods.

Brachiopods were much more diverse and common in the past than they are today. They live attached to surfaces on the seafloor and filter the food they need from passing water. Because they have two valves, they are sometimes mistaken for bivalves (Phylum Mollusca), but are not at all similar in terms of their soft part anatomy. black and pink juicy couture purse But brachiopods are no mollusks at all, but bivalved sea creatures with tentacles that belong to a separate phylum. Their ventral and dorsal valves are opened and closed by a complicated system of muscles. Brachiopods without hinges (the former Inarticulata, now Linguliformea) have phosphatic shells and live within muddy seafloors or as epizoans. doctorate of clinical nutritionkansas university sportsannie in kc A phylum is a taxonomic rank that divides the three kingdoms into more specific groups of organisms with related characteristics.
