What is the meaning of Euplectella?

Euplectella aspergillum

Likewise, what is the phylum of Euplectella?

Kingdom: Animalia
Phylum: Porifera
Class: Hexactinellida
Order: Lyssacinosida

Also to know, is Euplectella sessile?

aspergillum is found at such great depths the information about its active life is limited. This is a sessile animal that protrudes from the rocky ocean bottoms also making it a benthic (bottom dweller) animal (Buchsbaum and Pearse 1987; Hickman, Roberts, and Larson 1997; Kaestner 1967).

Why Venus flower basket is given as a wedding gift?

Known as the Venus Flower Basket, this artefact is actually the skeleton of a deep ocean sponge. In traditional Asian cultures it was given as a wedding gift (in its dead, dry state) because the sponge symbiotically houses two small shrimps, a male and a female, who live out their lives inside the sponge.

How do sponges reproduce?

Sponges may reproduce sexually and asexually. After fertilization in the sponge, a larva is released into the water. It floats around for a few days and then sticks to a solid to begin its growth into an adult sponge. Sponges are also able to reproduce asexually through budding.

How much water can a sponge filter?

A sponge that is 4 inches (10 centimeters) tall and 0.4 inch (1 centimeter) in diameter pumps about 23 quarts (22.5 liter) of water through its body in one day. To obtain enough food to grow by 3 ounces (100 gram), a sponge must filter about 275 gallons (1,000 kilograms) of seawater.

What are the characteristics of Spongilla?

They are generally marine aquatic organisms, with a few freshwater species. Their bodies are asymmetrical. Body shape can be cylindrical, vase-like, rounded or sac-like. They are diploblastic animals with two layers, the outer dermal layer and the inner gastral layer.

Where are glass sponges found?

Glass sponges in the class Hexactinellida are animals commonly found in the deep ocean. Their tissues contain glass-like structural particles, called spicules, that are made of silica (hence their name).

What do Venus flower basket eat?

Euplectella species feed on organic debris and microscopic organisms that are drawn into its central cavity through numerous holes in the body wall. The skeleton of Venus’s flower basket is a prized curio.

How many germ layers does a Euplectella have?

two germ layers

What type of spicules does grantia have?

Spicules are the mineral parts that form the skeleton of the grantia and are often composed of calcium carbonate or silica.

Which is the example of sessile animals among following?

Sessile animals such as sponges, corals, and anemones attach themselves to the bottom or substrate. This sessile lifestyle is advantageous to these organisms, because they do not have to expend large amounts of energy to move through the water to get food.

Which is the example of sessile animal among?

Sessile animals are animals that attach to a surface and stay in the same place for most of their time, sometimes not moving at all (e.g. stony corals, sponges), sometimes moving rarely and extremely slowly (e.g. anemones, some soft corals).

Is chiton a sessile animal?

IV POLYPLACOPHORA (CHITONS) Chitons are untorted, bilaterally symmetrical molluscs with a distinct head and a shell composed of a longitudinal series of eight shingle-like, overlapping plates. The majority of chiton species inhabit marine rocky shores, where they graze on encrusting algae and sessile animals.

Which sponge is commonly known as glass rope sponge?

The Hexactinellida are commonly known as the glass sponges and include the Venus’ flower basket (Euplectella spp.)
