Manta Ray diving can be an unforgettable experience.  These gentle giants are both graceful and magnificent Manta Ray Divingreminders of the wonders in our oceans.  Come dive with us off the coast of Hawaii and enjoy these magnificent creatures.

This Manta Ray video was shot off the coast of Kona in Hawaii. It was a marvelous dive. We saw 54 Manta Rays on two dives. 17 on a later afternoon dive and another 37 on the night dive. It was quite an experience.

Manta Ray diving can be an awesome experience.  The magnificent Giant Oceanic Manta Ray, Manta birostris, is something special to experience.  The largest recorded Oceanic Manta Rays was more than 25 ft (7.6m) across from wing-tip to wing-tip and weighed over 5,300 pounds (2,400 kg).  Manta Rays have a short tail and no stinging spine.

Manta Rays are very acrobatic and on this dive you will be able to see them perform aerobatic flips and rolls as they glide through the water all about you.

Manta Rays were first described by Dondorff in 1798 and named Manta birostris. Other synonyms for Manta Rays include Cephalopterus vampyrus Mithchell 1824, Cepahalopterus manta Bancroft 1829, Manta americana Bancroft 1829, Ceratoptera johnii Müller & Henle 1841, Ceratoptera alfredi Krefft 1868, Brachioptilon hamiltoni Hamilton & Newman 1849, Raja manatia Bloch & Schneider 1801, Manta hamiltoni Hamilton & Newman 1849, and Manta alfredi Krefft 1868.

The Manta Ray is one of the largest fishes, and has been know to reach 9 m (29.5 ft) and weigh as much as 1,350 k (3,000 lb).  The Manta Ray’s lifespan is thought to be about 20 years.  They are close relatives of sharks, which are also one of their main predators along with certain types of whales.  They are a close relative to the stingray, but they do not have a stinging tail.

What do you think of when you hear the term “Coral Reefs” or when someone asks “What are coral reefs”?. Some may think of the Great Barrier Reef in Australia while others may think of the reefs

surrounding the Caribbean islands or yet someone else may think of aqua-blue water and long sandy beaches surrounding their favorite island or tropical get away.

Coral reefs are definitely related to each of these but they are much, much more.

While Coral reefs cover less than one tenth of one percent of the earth’s oceans these same reefs are estimated to contain one quarter of known marine fish species (Smithsonian Institute).

Corals are tiny animals which belong to the group cnidaria (the “c” is silent). Other cnidarians include hydras, jellyfish, and sea anemones. Corals are sessile animals, meaning they are not mobile but stay fixed in one place. As corals grow and expand, they will form one three reef types:

  • Fringing
  • Barrier or
  • Atoll

All three reef types of coral reefs—fringing, barrier and atoll—share similarities in their bio-geographic profiles.

This series of articles we will answer the following questions:

What are Coral Reefs?
Where are they located and How were they formed?
What are the different types of Coral Reefs?
What types of creatures inhabit them?
What are the threats to Coral Reefs?
What are the potential impacts of these threats on us from the impacts to our economy, to food supplies, to medicines and more?
What if anything should we be doing to help the reefs?
How can you help?

So come join in the discovery of our coral reefs and the underwater world that is so amazing and important to each and everyone one of us.

Be sure to follow on our continuing series of articles as we explore the amazing world of coral reefs.

The world of coral reefs contains one of the most diverse environments on our planet, supporting

more species per square meter than any other ocean ecosystem. Creatures of the Coral Reef examines the phenomenal diversity of our coral reefs which are sometimes called the rain forests of the sea.  From the microscopic to the gigantic, coral reefs support and nurture a tremendous variety of creatures.

These reef systems have been built up over thousands of years by tiny  calcium-producing organisms.  These Creatures of the Coral Reef have constructed a haven for countless forms of life, some of which seem totally alien in form. It is a “Star Wars” world of bright colors, ever changing patterns and odd shaped creatures that look as though they came directly from central casting. Only on the coral reef can one find living examples from nearly every group of organisms.

Scuba Diving on a coral reef gives you some idea about what it would be like to explore another planet. Drifting weightless across this diverse landscape enables you to appreciate some of the tremendous complexity and simplicity that makes up the coral reef.

Man has spent a relatively modest effort scientifically exploring the world’s oceans compared to the time and money that has gone into exploring the surface of the Moon and other planets. Yet, the growing and ongoing exploration of our oceans continues to bring the discovery of new species, the identification of different environments where marine life flourishes and a little more understanding of our underwater world.

It is a place of never-ending wonders. The world of the coral reef is also an extremely fragile environment, and it is under considerable pressure and facing real dangers to its continued existence. The distress and destruction of coral reefs has a noticeable impact on our lives from the foods we eat to the air we breathe.   From the Florida

Keys to the Great Barrier Reef in Australia, to the atolls of the Pacific and islands of the Indian Ocean our coral reefs need our help. If we wish to leave a healthy and thriving reef system to our children and their children we need to understand the threats to this amazing environment and understand actions that can be taken to preserve and restore our reefs.  These are our oceans and the first step to helping protect coral reefs is education.

This segment provides a high-level overview of the basic types of Creatures of the Coral Reef, including:
