Euplectella comprises marine sponges. They have silica spicules, which are also known as glass sponges. Euplectella has Venus flower baskets and is widely found in the deep ocean and marine water. They are associated with shrimp and offered as a wedding gift in Japan, as it is the epitome of togetherness.

Euplectella is a genus that contains sponges from the sea. Syconoid is the canal system that helps them to control and regulate the water. The water circulation occurs through the canal system. They are in a basket-like structure, which looks like a vase. Euplectella is classified under the phylum Porifera. The aspergillum is the widely known species of Euplectella.

Amebocytes connected to the disintegrating sponge show asexual reproduction. The epithelial cells enclose the amoebocytes, and once the decaying sponge vanishes, the new organism comes from the clump of cells.
In sexual reproduction, the sperm enters the sponge and fertilises the egg. The fertilisation is completed by amebocyte. Both the amebocyte and the sperm enter the ovum, which becomes a cytostome that intakes the sperm and the carrier cell. Once the zygote undergoes radial holoblastic cleavage, it results in new cells of the same size and shape. The evenly mature embryo becomes a new sponge.
Q1. Euplectella is classified under ___________ class.
a. Animalia
b. Porifera
c. Hexactinellida
d. Lyssacinosida
Ans: Hexactinellida
Euplectella is a Hexactinellida with six-rayed silica spicules, classified under Porifera phylum.
Q2. Euplectella is classified under ___________ Kingdom.
a. Animalia
b. Porifera
c. Hexactinellida
d. Lyssacinosida
Ans: a. Animalia
Euplectella is a heterotrophic multicellular eukaryotic creature that belongs to the Animalia kingdom. It has multicellularity, no cell walls, and specialised tissues and organs in common with other animals.
Q3. Which of the following is the reason for the glassy appearance of Euplectella?
a. Flagellum
b. Sponges
c. Silica spicules
d. Triaxon spicules
Ans: c. Silica spicules
The glassy look of Euplectella is caused by the silica spicules that make up its skeleton. Triaxon spicules contribute to the intricate lattice-like structure.
Q1. Where does Euplectella live?
Answer: Euplectella mostly lives deep in the sea at approximately 100m to 1000m under the surface. They are commonly found in areas near Japan and also in the Indian Ocean.
Q2. What are the applications of Euplectella?
Answer: Euplectella takes silicon acid from saltwater and transforms it to silica, and becomes into complex glass fibre. The skeletal structure of a new form of structural lattice employed in engineering applications.
Q3. What is meant by Animal Kingdom?
Answer: The animal kingdom is a classification of various species that are eukaryotic, multicellular species. All the animals have their unique structure, characteristics and habitat.
