Activities like deep-sea mining could disrupt these remote environments as well as the species that live there-both the ones we know about and the ones we don’t. There’s still a lot more to learn about harp sponges, but they seem to thrive in the extremely stable environment of the flat, muddy seafloor in a relatively narrow depth range. What internal organs do sponges have Sponges do not have internal organs. What type of symmetry does this animal have This animal is asymmetrical. The feeding strategy is more efficient for animals adapted to the food-poor deep-sea environment, where filter-feeding costs valuable energy. What is the name of the cavity of a sponge Central cavity. The harp sponge is not the first carnivorous sponge scientists have discovered in the deep sea, although carnivory remains an exception among sponges. The sponge’s elegant structure, which it likely evolved to maximize the area available for snaring food, inspired scientists to name the carnivorous deep-sea predator the harp sponge ( Chondrocladia lyra). But in 2012, scientists on a research voyage off the coast of northern California discovered a sponge that uses small hooks along its vertical branches to entrap and devour larger, more nutrient-dense prey, like small crustaceans. Most sponges are simple filter feeders-they eat small plankton and bacteria that they ‘filter’ from the surrounding water which they pump through their bodies. The most important structure is the system of canals and chambers, called a water-current system, through which water circulates to bring food and oxygen to the sponge. The particles are taken in by the cells through phagocytosis, and they are subsequently digested and wastes are expelled. Sponges accomplish digestion by digesting food particles within specialized cells, a process known as intracellular digestion. There’s nothing angelic about this covert predator. How do sponges move - Answers Subjects > Animals & Plants > Mammals How do sponges move Wiki User 23:13:52 Study now See answer (1) Best Answer Copy sponges don't. Amoebocytes are able to move through the sponges body & transfer digested food from the choanocytes to porocytes & the epidermal cells that. Form and function Sponges are unusual animals in that they lack definite organs to carry out their various functions. Filter feeding or filtering food particles from water is how they get food.
