Thus, the simple structure of these poríferas is reduced to the capture of particles dissolved in the water, which can be organic matter, unicellular algae, debris and bacteria that are digested through the phagocytosis. In advance it is discarded that of complex beings, since having no digestive system can not"eat"as other marine animals. It is not possible to talk about how sponges feed themselves without saying what it is that they feed on. It is in the ostiolos where the water is absorbed and that is why this vital liquid passes to the ossicles, where it is expelled, not before passing through the coanocitos, which is the place where the current is maintained in which the particles Of the food is trapped. If there is something that makes it possible to feed the sponges, it is the presence of channels that, having flagellated cameras, connect the ostiolos, which are mostly covered by the coanocitos. The sponges do not have an active feeding, since they are sessile animals, that is to say, they are attached to the substrate where they live, like the bed of the sea, reason why they can not move of its surroundings.Īs a result, sponges have a passive diet which, in other words, means that they obtain their nutrients by taking them from the surrounding environment Environment in which they float freely. Since sponges do not have real tissues or organs (therefore they have no digestive system, such as that of more complex living things), their only means of survival is in their pores. It consists of a cell mass in the form of a sac through which the water circulates, in which is the oxygen that allows it to breathe and the food with which it subsists.
What is the process by which sponges feed?įeeding Sponges, Responds to its anatomical structure, which is quite simple.
