What features distinguish grantia as an animal?
Grantia are a type of simple sponge-like animals that belong to the phylum Porifera. They lack true tissues and organs, and their bodies are organized into simple layers of cells surrounding a central cavity. One distinctive feature of grantia is their filter-feeding mechanism, where they draw in water through pores in their bodies to obtain food.
What types of spicules give a sponges body support?
Sponges have different types of spicules that provide support to their bodies. These can be made of calcium carbonate, silica, or spongin. Calcium carbonate spicules are needle-like and provide rigidity, while silica spicules are more delicate and form intricate structures. Spongin spicules are organic fibers that give flexibility to the sponge's body.
What function might spicules provide?
Spicules in some marine organisms, such as sponges, provide structural support and protect against predators. They can also aid in capturing food particles by creating a mesh-like structure that traps prey. Additionally, spicules can serve as a defense mechanism by deterring or injuring potential predators.
How would you test the hypothesis that spicules deter predators?
To test the hypothesis that spicules deter predators, I would conduct a controlled experiment comparing predator behavior toward prey with and without spicules. This could involve offering both types of prey to a variety of predators in a controlled environment and observing the frequency and duration of predation attempts. Additionally, measuring any physical damage or feeding success on both prey types would provide further evidence. Analyzing the data statistically would help determine whether the presence of spicules significantly affects predator behavior.
Name some sponges?
Hexactinellida, Calcarea, Demospongiae, andSclerospongiaeTechnically, however, the Sclerospongiae are not considered sponges. They are very similar, but they are not the same. Like bats and birds who have both evolved the ability to fly but are not the same types of animals, Slerospongiae have evolved and became very similar to sponges, but they are not sponges.
What class do Grantia belong to?
Grantia belong to the class Calcarea, a class of marine sponges characterized by their calcareous (calcium carbonate) spicules. They are filter feeders that are commonly found in shallow coastal waters.
When was Grantia compressa created?
Grantia compressa was created in 1780.
What phylum does the grantia belong to?
Porifera. http://en.wikipedia.org/wiki/Grantia
Bodies of sponges contain sharp structures?
Yes, they are called spicules, not pores or spiracles as many people think.

What are the functions of spicules in sponges?
Spicules provide structural support.
What type of symmetry does a grantia have?
It's asymmetrical.
What is the role of spicules sponges?
Spicules, like our skeleton, give the sponge structure. Without spicules, Sponge Bob would be Sponge Blob.
