Dear student, Sponges have many pores in their body through which water enters their body and they captures food. Due to the presence of these pores sponges are known as porous animals.

Is a sponge an animal?

sponge, any of the primitive multicellular aquatic animals that constitute the phylum Porifera. They number approximately 5,000 described species and inhabit all seas, where they occur attached to surfaces from the intertidal zone to depths of 8,500 metres (29,000 feet) or more.

What are the 4 types of sponges?

Calcarea, Hexactinellida, Demospongiae, and Homoscleromorpha make up the four classes of sponges; each type is classified based on the presence or composition of its spicules or spongin. Most sponges reproduce sexually; however, some can reproduce through budding and the regeneration of fragments.

What are the 3 types of sponges?

Most sponges fall into one of three categories, based on their canal systems - asconoid, syconoid and leuconoid.

What are the examples of Ovoviviparous animals?

Some examples of ovoviviparous animals are sharks, rays, snakes, fishes, and insects. Oviparity is different from ovoviviparity in a way that the eggs in oviparity may or may not undergo internal fertilization but are laid and depend on the yolk sac to get nourished till the time they hatch.

Is jellyfish an animal?

jellyfish, any planktonic marine member of the class Scyphozoa (phylum Cnidaria), a group of invertebrate animals composed of about 200 described species, or of the class Cubozoa (approximately 20 species).

What animal has 32 brains?

Leech has 32 brains. A leech's internal structure is segregated into 32 separate segments, and each of these segments has its own brain. Leech is an annelid.

Are bath sponges alive?

The natural sponges we use in our baths are actually animal skeletons. Bath sponges consist of a highly porous network of fibres made from a collagen protein called spongin. The skeletons are obtained by cutting the growing sponges and soaking the cut portions in water until the flesh rots away.

What kind of animals are sponges?

Sponges constitute the phylum Porifera, and have been defined as sessile metazoans (multicelled immobile animals) that have water intake and outlet openings connected by chambers lined with choanocytes, cells with whip-like flagella.

Is a sea sponge a fish?

When you look at a sponge, the word "animal" might not be the first that comes to mind, but sea sponges are animals. There are over 6,000 species of sponges; most live in the marine environment, although there are also freshwater sponges. ... It is through these pores that the sponge draws in water from which it feeds.

What kind of sea sponge is SpongeBob?

He filter-feeds in "I Had an Accident" and reproduces by budding in multiple episodes, including "Pressure." In The SpongeBob Musical, SpongeBob's exact species of sea sponge is identified: Aplysina fistularis, a yellow sea sponge commonly found in open waters.

What makes a sponge porous?

The walls of these sponges are thin, lack canals, and are perforated by pores, which actually are openings through cells (porocytes). ... Water enters very small pores found among the cells (pinacocytes), which line the outer surface of the sponge.

What are two species of sponges?

The approximately 8,550 living sponge species are scientifically classified in the phylum Porifera, which is comprised of four distinct classes: the Demospongiae (the most diverse, containing 90 percent of all living sponges), Hexactinellida (the rare glass sponges), Calcarea (calcareous sponges), and Homoscleromorpha ...

What is a marine sponge?

Marine sponges are sessile animals that look like plants. They attached themselves to a rock, shell or seafloor when they are young and there live for the rest of their lives. They filter water through their porous body for the food they eat.
