"The best way to observe a fish is to become a fish."
Marine life is the essence of why we dive, so in this section we explore information on the biology, morphology, behavior, ecological relationships, taxonomy, and conservation status of the fascinating marine life that inhabits the ocean from nanoplankton to blue whales.
Enrich your dive experience with practical knowledge of the life you will encounter below the surface of the water.
The plant kingdom is made up of multi-cellular, photosynthetic Eukaryotas. These multi-cellular organisms contain specialized cells that perform different tasks. Algae are some of the simplest aquatic plants, often referred to as seaweed in the marine environment. Marine algae are abundant throughout the ocean and can either float freely or cling to substrate such as…Read More
Vertebrates Vertebrata are among the most structurally complex organisms. Marine vertebrates, classified under the phylum Chordate and class vertebrata, are among the most structurally complex organisms. The seven main classes in Vertebrata are: Agnatha, Chondrichthyes (“Chondree-ICK-thees”), Osteichtheyes (“Ostee-ICK-thees”), Amphibian, Reptilian, Aves, and Mammalia. The first three classes in Vertebrata are all a form of fish. In class Agnatha…Read More
Animals that lack backbones are known as invertebrates. Over 98% of species on earth are invertebrates that rely on other strategies for support such as hydrostatic pressure, exoskeletons, and in some, even glass spicules. Some invertebrate phylum’s have only one species while others like Arthropoda include more than 800,000 species. The most common marine invertebrates…Read More
