Are corals porifera?

no! that is just not possible. corals are cnidarians. when the minute creatures called polyps die, they secrete a hard exoskeleton consisting of calciumcarbonate. they secrete it around them to form a hardened structure called corals. corals are basically dead and hardened polyps.


What are the organisms that live in colonies of polyps and secrete an exoskeleton of calcium carbonate?

Corals are organisms that live in colonies of polyps and secrete an exoskeleton of calcium carbonate. These structures form the framework of coral reefs, providing habitat for a diverse array of marine life.


An anthozoan that lives in colonies that sectetes a hard outer skeleton?

The anthozoan that fits this description is a coral. Corals are colonial animals that secrete a hard exoskeleton made of calcium carbonate. This exoskeleton provides structure and support for the coral colony.


Are corals invertebrate?

Does Coral Have Bones?

Corals produce a calcified mineral exoskeleton that is white in appearance. Dead coral from thousands of years ago is dug up in the ground, crushed, and sold as a healthy calcium supplement for humans and animals. Corals are symbiotic with Algeas that give brilliant colors on top of the exoskeleton. They need one another to survive. Recently higher water temperatures have been killing the algaes, leading to the phenonmenon known as coral bleaching. In time, the bleached corals also die. This is a threat to the entire reef ecosystem and has repercussions across all marine ecosystems and perhaps the entire world ecosystem.

Differences between hermatypic and ahermatypic corals?

Hermatypic corals contain zooxanthellae (a symbiotic algae), whereas ahermatypic corals do not. It is like saying that hermatypic corals are photosynthetic, where ahermatypic corals are non photosynthetic.
