Finger Coral (Acropora humilis) Dimensions & Drawings

What does coral eat?

Most corals have a symbiotic relationship with algae living in their tissues. These algae provide them with the right nourishment or energy that they generate from the sun. Still, others feed on small fish, plankton, and even cetaceans by stinging and capturing them with their long tentacles. Most corals feed at night.

How does Anthozoa reproduce?

Anthozoa can reproduce sexually or asexually. Asexual reproduction can be transverse, pedal laceration, longitudinal fission, or autotomy of tentacles. Members of this group release sperm and eggs into the water. When the egg is fertilized, it transforms into a larva, and then the last stage, which is polyps.

What gives Anthozoa its internal color?

Anthozoa has soft body tissues. To protect these soft tissues, it secretes a hard and tall nonliving substance. Algae love this substance as it offers them protection and components for photosynthesis. The algae are what gives the Anthozoa its color, which can be pink, yellow, red, and many more.

What do cnidarians use for defense?

Cnidarians are aquatic animals with two body forms (the ectoderm and endoderm separated by a mesoglea). To capture prey or even defend themselves, cnidarians have unique and well-developed specialized cells in their mouths and tentacles for stinging attackers. These cells, called cnidocytes, have toxins that are released when their body is touched.

How do cnidarians reproduce?

Sexual and asexual reproduction are the forms of reproduction seen among cnidarians. Besides, some are hermaphrodites — capable of producing both eggs and sperms at the same time. However, asexual reproduction is the most common in this species. Sexual reproduction may occur only in one phase of a cnidarian’s life cycle.

Do cnidarians have brains?

What cnidarians have are diffuse nets of nerves that coordinate messages around their bodies. Research shows that these nets of nerves are just as complex as that of human beings. In addition, some like jellyfish, have no heart or eyes. Most cnidarians also have a transparent body covered in a chitinous exoskeleton.

How do invertebrates protect their soft bodies?

Invertebrates can effectively protect their soft bodies through an outer hard casing that is referred to as the exoskeleton. Invertebrates like spiders, crustaceans, and insects have their exoskeletons made through sections of jointed legs. Others like mollusks like snails and clams have a hard shell in which they can hide when danger is present.

What is the difference between an invertebrate and a vertebrate?

The difference between an invertebrate and a vertebrate is that invertebrates have no backbones while vertebrates have a developed internal skeleton with cartilage and bones as well as a developed brain that is protected by a skull. Vertebrates also cannot make their food, while invertebrates make their food.
