How do a giant barrel sponge defend itself?
The oldest known Giant Barrel Sponge was 2300 years old and died of the Sponge Orange Band in a few weeks. The larvae produced by the Giant Barrel Sponge have chemical defenses against predators and derive nutrition from the yolk.
What color is the giant barrel sponge?
It is typically brownish-red to brownish-gray in color, with a hard or stony texture. The giant barrel sponge has been called the “redwood of the reef” because of its size and estimated lifespan of hundreds to a thousand or more years.
What kingdom does the giant barrel sponge belong to?
AnimalGiant barrel sponge / KingdomAnimals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and Wikipedia

What makes giant barrel sponge unique?
Giant barrel sponges can live hundreds or even thousands of years. They reproduce throughout the year by releasing sperm and egg cells from their osculums into the water column or in the bodies of other sponges, which then fuse to form embryos. Sponges are hermaphroditic, meaning they produce both sperm and egg cells.
How do barrel sponges breathe?
Sponges are animals that belong to the phylum Porifera, which means “pore-bearing.” Sponges breathe by moving water through pores, called ostia, which cover their body.
How old does a barrel sponge have to be?
The oldest giant barrel sponge measured in the study was estimated to be 127 years old. The team also estimated, from a photograph, that a giant barrel sponge discovered off of the Caribbean island of Curacao in 1997 was about 2,300 years old.
How are sponges used in medicine?
When scientists have screened cells from sponge tissues they found compounds with the potential for an incredible range of medicinal properties including: antibacterial, antiviral, antifungal, antimalarial, antitumor, immunosuppressive, and cardiovascular activity.
How do sponges defend themselves?
Sponges do not have nervous systems that would allow them to respond to changes in their environment. However, many sponges protect themselves by producing toxins that make them unpalatable or poisonous to potential predators.
Can sponges breathe out of water?
Sponges Respire Through Diffusion Sponges do not have complex digestive, circulatory or respiratory systems to move nutrients and oxygen around their bodies. Rather, each cell is independent and performs its own oxygen, food and waste processes using diffusion.
How much water can a giant barrel sponge pump?
Giant barrel sponges can filter up to 50,000 times their own volume in water in a single day. They also provide habitat to several small fish and other invertebrates that can be found living inside or on the surface of the sponge.
How much is black coral worth?
When the main trunk is wider, longer, more branches, etc, good solid black color with no problems the price can go upwards of $20. Select pieces that are cut for specific purposes can be worth $2-5. Antipatharian coral of same size and quality can go upwards of several hundreds of dollars.
What is Apple coral?
APPLE CORAL, is part of the species of corals known as melithaea ochracea, which is commonly found on the ocean floors around the waters of Taiwan, Indonesia and southern China. It brings good luck to its owner.
Do sponges have antibacterial properties?
Sponge-derived or other marine microorganism’s associated bioactive substances have possessed antibacterial, antiviral, antifungal, antimalarial, anthelminthic, immunosuppressive, muscle relaxants and anti-inflammatory activities. Sponge substances have remarkable chemical diversity.
How are sponges beneficial to humans?
Many of these natural products from sponges have shown a wide range of pharmacological activities such as anticancer, antifungal, antiviral, anthelmintic, antiprotozoal, anti-inflammatory, immunosuppressive, neurosuppressive, and antifouling activities.
Do sponges have a defense mechanism?
Sponges have evolved a variety of chemical and structural defense mechanisms to avoid predation. While chemical defense is well established in sponges, studies on structural defense are rare and with ambiguous results.
What do sponges uses as a line of defense against predators?
Because sponges are sessile they cannot flee from predators. Their sharp spicules provide some defense. They also produce toxins that may poison predators that try to eat them.
What do sponges often have for protection?
Sponges that reproduce asexually produce buds or, more often, structures called gemmules, which are packets of several cells of various types inside a protective covering.
Why is the barrel sponge important to the reef community?
The giant barrel sponge is an important member of the reef community. Sponges filter large amounts of water, and are a predominant link in benthic-pelagic coupling on reefs and they harbor diverse assemblages of bacteria that can take part in nitrification and carbon fixation.
Is a barrel sponge a dioecious animal?
The giant barrel sponge is probably dioecious, and spawns its eggs or sperm directly into the water column. Clouds of sperm from males are emitted from the osculum, while females produce flocculent masses of eggs that are slightly negatively buoyant.
What is the shape of a giant barrel sponge?
The giant barrel sponge is variable in form. It is very large and firm, typically being barrel-shaped, with a cone-shaped cavity at the apex known as the osculum. However, some individuals within the same population may be low and squat or relatively tall and thin.
What gives a barrel sponge its color?
The tissues of the giant barrel sponge contain photosynthetic symbiotic cyanobacteria, Synechococcus Spongiarum, which give the sponge its color. Individuals may undergo periodic bleaching, but this is a cyclic event, and the sponge recovers its normal coloration over time.
