What is a sponge?
Sponges, the members of the phylum Porifera ( / pəˈrɪfərə /; meaning 'pore bearer'), are a basal Metazoa (animal) clade as a sister of the Diploblasts.
What is the body of a sponge made of?
A sponge's body is hollow and is held in shape by the mesohyl, a jelly-like substance made mainly of collagen and reinforced by a dense network of fibers also made of collagen . The inner surface is covered with choanocytes, cells with cylindrical or conical collars surrounding one flagellum per choanocyte.
How tall is a leuconoid sponge?
For example, in Leuconia, a small leuconoid sponge about 10 centimetres (3.9 in) tall and 1 centimetre (0.39 in) in diameter, water enters each of more than 80,000 intake canals at 6 cm per minute.
What is the skeleton of a sponge?
Skeleton. In zoology a skeleton is any fairly rigid structure of an animal, irrespective of whether it has joints and irrespective of whether it is biomineralized. The mesohyl functions as an endoskeleton in most sponges, and is the only skeleton in soft sponges that encrust hard surfaces such as rocks.
How fast can a sponge move?
Although adult sponges are fundamentally sessile animals, some marine and freshwater species can move across the sea bed at speeds of 1–4 mm (0.039–0.157 in) per day , as a result of amoeba -like movements of pinacocytes and other cells.
Which cell transports food from a sponge to the vesicles?
Since the smallest particles are by far the most common, choanocytes typically capture 80% of a sponge's food supply. Archaeocytes transport food packaged in vesicles from cells that directly digest food to those that do not.
What are the steps of the sponge loop?
Steps of the sponge loop pathway: (1) corals and algae release exudates as dissolved organic matter (DOM), (2) sponges take up DOM, (3) sponges release detrital particulate organic matter (POM), (4) sponge detritus (POM) is taken up by sponge-associated and free-living detritivores.
What is a sponge?
Sponges are invertebrate, aquatic animals belonging to the Phylum Porifera. They are filter feeding organisms, meaning that their bodies are specialised to separate suspended food particles out of the water. They spend their adult lives attached to the seabed (i.e., they are sessile benthic organisms). As the name Porifera (‘pore bearers’) ...
How is water pumped through the body?
Water is pumped through the body in a system of flagellated canals where food and other metabolites are extracted by the sponge. Sponges are thought to be the oldest living animal group: they are known to have existed for over 600 million years.
How deep are sponges?

Where are sponges found?
These are found globally on continental shelves, slopes, seamounts, and mid-ocean ridges, and in submarine canyons and fjords.
Where is the giant barrel sponge found?
It is one of the most commonly found sponges on the Coral reefs in the Caribbean region. It is also referred to as the “Redwood of the Sea” because of its large size and long life span.
What is the role of giant barrel spoons in the ecosystem?
Giant Barrel Sponges play a vital ecological role. It helps improve water clarity, supports reef regeneration, and provides a habitat for other invertebrates, benthic fish, and bacteria. It plays a vital role in the food chain and also recycles nutrients for all the reef organisms.
Why is a sandbox important to the reef?
It helps improve water clarity, supports reef regeneration , and provides a habitat for other invertebrates, benthic fish, and bacteria. It plays a vital role in the food chain and also recycles nutrients for all the reef organisms.
How big can a giant barrel sponge get?
Known to be one the largest species of sponge, Giant Barrel sponges can grow up to several meters in diameter. The smallest individual sponges observed are about one centimeter in size, while the largest ones can reach up to 2 meters in diameter.
What are the physical characteristics of a giant barrel sponge?
It is typically shaped like a barrel, with a hole at the top of the central cavity known as the osculum. Small sponges are cone-shaped.
Is a giant barrel sponge a sessile organism?
Some are smooth, while some are rough or rugged and may also have small spikes. The Giant Barrel Sponge is a sessile organism, which means it is fixed in one place. In some areas, the sponge can account for about 9% of the total reef substrate.
What is the color of a sponge?
Due to the presence of Cyanobacteria symbionts, its color ranges from salmon pink to purple. The most common colors are brown, reddish-brown, grey, and purple.
How deep is the ocean?
Since the ocean is on average 3 miles deep, it may not surprise you that the water column is not uniform. In fact, sections of the water column in the ocean are differentiated by pressure, light, temperature, oxygen and mineral nutrients.
Why is the water column not uniform?
Since the ocean is on average 3 miles deep, it may not surprise you that the water column is not uniform. In fact, sections of the water column in the ocean are differentiated by pressure, light, temperature, oxygen and mineral nutrients. It is because of these elements that certain sections of the ocean only contain certain marine animals.
What are the elements that make up the water column of the ocean?

How many zones are there in the ocean water column?
The ocean water column is made up of 5 zones. The sunlight zone, the twilight zone, the midnight zone, the abyss and the trenches.
What is the sun zone?
Sunlight Zone. This zone extends from the surface down to about 700 feet. This is where most of the visible light is and with light comes heat. This is where the wide range of temperatures occur. Most marine animals live in this zone and feed off of photoplankton (the basis of the ocean food chain) and smaller fish.
What do marine animals eat?
Most marine animals live in this zone and feed off of photoplankton (the basis of the ocean food chain) and smaller fish. Photoplankton is responsible for almost half of the earth’s oxygen released in the atmosphere.
How deep is the Twilight Zone?
Twilight Zone. This zone extends from 700 feet down to about 3,280 feet. The light that reaches this zone is pretty faint. Larger fish like, whales and giant squid dive to these depths to feed. It is in this region that we start to see bioluminescent fish and all sorts of bizarre looking fish.
Summary
Overview
Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells. Unlike other animals, they lack true tissues and organs. Some of them are radially symmetrical, but most are asymmetrical. The shapes of their bodies are adapted for maximal efficiency of water flow through the central cavity, where the water deposits nutrients and t…
Etymology
The term sponge derives from the Ancient Greek word σπόγγος (spóngos 'sponge').
Distinguishing features
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. However, a few carnivorous sponges have lost these water flow systems and the choanocytes. All known living sponges can remold their bodies, as most types of their cells can move within their bodies and a few can change from one type to an…

Vital functions
Although adult sponges are fundamentally sessile animals, some marine and freshwater species can move across the sea bed at speeds of 1–4 mm (0.039–0.157 in) per day, as a result of amoeba-like movements of pinacocytes and other cells. A few species can contract their whole bodies, and many can close their oscula and ostia. Juveniles drift or swim freely, while adults are stati…
Ecology
Sponges are worldwide in their distribution, living in a wide range of ocean habitats, from the polar regions to the tropics. Most live in quiet, clear waters, because sediment stirred up by waves or currents would block their pores, making it difficult for them to feed and breathe. The greatest numbers of sponges are usually found on firm surfaces such as rocks, but some sponges …
Systematics and evolutionary history
Linnaeus, who classified most kinds of sessile animals as belonging to the order Zoophyta in the class Vermes, mistakenly identified the genus Spongia as plants in the order Algae. For a long time thereafter sponges were assigned to a separate subkingdom, Parazoa ("beside the animals"), separate from the Eumetazoa which formed the rest of the kingdom Animalia. They have been reg…
