Sponges typically have a biphasic (pelagobenthic) life cycle in which embryogenesis results in a free-swimming lecithotrophic larva, which then settles and metamorphoses into a sessile, filter-feeding juvenile that grows into a mature adult (reviewed by Ereskovsky [2010] ).

Do sponges show metamorphosis?
Metamorphosis occurs in at least 17 phyla of the animal kingdom, including Porifera (sponges), Cnidaria (jellyfish and others), Platyhelminthes (flat-worms), Mollusca (mollusks), Annelida (segmented worms), Arthropoda (insects and others), Echinodermata (sea urchins and others), and Chordata (vertebrates and others).
What is metamorphosis in sponges?
Sponge metamorphosis Definition
The process of modification in the body pattern of certain organisms during their stage of development from an immature stage to an adult is termed as Metamorphosis. The primitive organism which is multi-cellular in nature and belongs to the phylum Porifera is known as Sponges.
What is metamorphosis in reproduction?
Reproduction in Animals | Exercise
The transformation of the larva into an adult through drastic changes is called metamorphosis. Metamorphosis is a biological process which involves sudden and abrupt changes in the body structure of the animal by cell growth and differentiation.
In which organisms does metamorphosis take place?
Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior.
What are examples of metamorphosis?
Metamorphosis occurs in animals such as amphibians, insects, and fish. The most common (and popular) examples of metamorphosis are the transformation of a tadpole to a frog and a caterpillar to a butterfly.
Why are sponges still classified as metazoans?
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.
What is the larval stage of sponges called?
Parenchymula is the larval stage in sponges. So, the correct answer is 'Parenchymula'.
What is the larva of a sponge called?
After reproduction, sponge produces larva called as stomoblastula. It has a mouth and feeds on nurse cells within mesogloea and grows for a few days. Stomoblastula develops into an amphiblastula by inverting inside out and brings the flagellated cells on the outer surface, so that the larva can swim in water.
What is metamorphosis in geography?
met·a·mor·phism. (mĕt′ə-môr′fĭz′əm) The process by which rocks are altered in composition, texture, or internal structure by extreme heat, pressure, and the introduction of new chemical substances.
What is metamorphosis give explain?
metamorphosis, in biology, striking change of form or structure in an individual after hatching or birth. Hormones called molting and juvenile hormones, which are not species specific, apparently regulate the changes.
What is metamorphosis and their type?
Metamorphosis is the change in the body form and habits during the development cycle of animals. Complete metamorphosis and incomplete metamorphosis are two growth types of insects where the body form of insects changes during their lifecycle. ... Complete metamorphosis consists of four stages: egg, larva, pupa, and adult.
How does evolution explain metamorphosis?
Complete metamorphosis likely evolved out of incomplete metamorphosis. ... They point out that insects that mature through incomplete metamorphosis pass through a brief stage of life before becoming nymphs—the pro-nymphal stage, in which insects look and behave differently from their true nymphal forms.
What is metamorphosis explain with the help of example?
The change that takes place when the larva is transformed into an adult is called as metamorphosis. This change takes place in stages in an organism's life. Metamorphosis can be observed in animals like frog and silk moth. The tadpole stage of frog and an adult frog is different. It metamorphosed into an adult frog.
What are two examples of metamorphosis which metamorphosis shows?
Example of metamorphosis:
The adult frog develops legs and other organs from the simple tailed tadpole stage. Insects: metamorphosis takes place from egg to larva to pupa and then to adult butterfly. The adult butterfly complete with wings and other organs look entirely different from the larval stage .
