Marine Life
Marine life is the essence of MarineBio, so in this section we explore the science, biology, taxonomy, morphology, behavior, and ecological relationships of marine life that inhabits our ocean.
Search/browse our growing database of endangered, threatened, and the most common marine species…
Marine biology is the study of life in the oceans and other saltwater environments such as estuaries and wetlands. All plant and animal life forms are included from the microscopic picoplankton all the way to the majestic blue whale, the largest creature in the sea—and for that matter in the world….
It wasn’t until the writings of Aristotle from 384-322 BC that specific references to marine life were recorded. Aristotle identified a variety of species including crustaceans, echinoderms, mollusks, and fish…

Taxonomy, Nanoplanktonic Flagellates, Cnidarians, Rotifera, Chaetognatha, Marine Gastropods, Polychaeta, Copepods, Cladocerans, Krill, Insect Larvae, Tunicates…
Marine vertebrates, classified under the Kingdom Animalia, Phylum Chordata and Subphylum Vertebrata, are among the most structurally complex organisms. The seven main superclasses and classes in Vertebrata are: Agnatha, Amphibia, Aves, Chondrichthyes (“Condr-ICK-thees”), Mammalia, Osteichthyes (“Ostee-ICK-thees”), and Reptilia.
Jacks, cod, sailfish, scorpionfish, tuna, marlin, parrotfish, angelfish, barracuda, sea horses, eels, etc.
Basking sharks, blue and bull sharks, the goblin sharks, great whites, hammerheads, lemon sharks, mantas and stingrays, nurse sharks, oceanic whitetips, tiger sharks, salmon sharks, threshers, whale sharks, wobbegongs, etc.
For generations, whales and other marine mammals have intrigued humans. 2,400 years ago, Aristotle recognized that whales are mammals, not fish, because they nurse their young and breathe air like other mammals. There are numerous myths and legends surrounding marine mammals. The Greeks believed that killing a dolphin was as bad as murdering a human.
Fur seals, sea lions, seals, polar bears, walruses and sea otters.
Find out about 16 species of rare beaked whales, 28 species of dolphins, 6 species of porpoises, 6 species of baleen whales, the dwarf and pygmy sperm whales, 4 right whales, the gray whale, 6 river dolphins, the narwhal, beluga, and sperm whales.
They’re the acrobats and court jesters of the sea, troops of aerial spinners and wave dancers. Their long sleek bodies jet high into the air as they perform a grand ballet with tails propelling them as they skim each wave against the continuous horizon. Mesmerizing to watch, dolphins have been gliding, flipping and dancing into our hearts for centuries.
Here we look at the development and uses of marine body types, common characteristics like fins, scales and shells. We’ll see how “different” marine life really is…
Let’s look at the different roles of marine life. We’re familiar with grazers and predators on land, how do they behave in the sea..?
We have fission, budding, eggs that hatch internally, eggs that hatch externally, live births, some start as plankton (zooplankton), some are born in fresh water, some are born on land…
Every form of interaction between different species is seen in the sea. Some creatures depend on each other for food, protection or a just a safe place to lay eggs. A parasite isn’t always bad… see examples of cooperation that we humans could learn from…
Marine life habitats, populations and interactions among organisms and their environment…
All organisms in an ecosystem can be placed in trophic levels depending what energy source they rely upon and how they provide energy for other organisms in their food web…
The way organisms interact within ecosystems. Food webs vs food chains, trophic levels, symbiosis, predators…
Complex webs of factors that fit together to form balanced life systems capable of withstanding most changes…
