• Each species is identified with two names:
a Genus name and the Species name.
• Ex. Atlantic Cod

Idenitifying Marine Organisms
• Some things we know by sight: fish, crab
• These words are different in other
languages: poisson, fisch, pescado, pesce.
• Scientists all over the world know that
Gadus morhua is Atlantic cod.
• There are many types of cod in the Genus
Morhua but only one species:
• Gadus morhua
Scientific Naming
• Scientists identify organisms by comparing
them to ones which are already known.
• If they are similar enough, they might be
in the same Genus, less similar in the
same Family. For example corals are in
the Phylum Cnidaria and lobsters are in
the Phylum Arthropoda because they are
very different from each other.
• A group of organisms that look alike and
can interbreed under natural conditions to
produce fertile offspring.
• When similar species are in close contact,
interbreeding can take place for example,
dolphin and whale to produce a wolphin.
These animals are infertile and can’t have
offspring so they are not new species.
Bottlenose Dolphin + False Killer Whale = Wholphin or wolphin
Tursiops truncatus (mother) + Pseudorca cracrassidens
