Classifying Marine Animals Cnidaria ( stinging celled ): Stingers in the Ocean Plankton = jellies & Portuguese man-of-war Benthic = coral, sea whip, & sea anemone http://toimage.blogspot.com/2012/06/sea-whip-coral-wallpaper.html http://www.hellobc.com/activitylisting/4556347/shaw-ocean-discovery-centre.aspx https://www.diversalertnetwork.org/health/hazardous-marine-life/portuguese-man-of-war
Classifying Marine Animals Phyla of Worms Many worms - are benthic; crawling or burrowing in sediment - swim or float - build tubes out of cemented sand grains & small shells - are parasitic & survive living on the gills or bodies of other marine animals. Some noteworthy & numerous groups are the flatworms (phylum Platyhelminthes) & segmented worms (phylum Annelida).
Classifying Marine Animals Phyla of Worms Flatworms (Platyhelminthes) - Flat, ribbonlike worms that have solid body cavity & one body opening. - Many survive as parasites on vertebrates. - Others are free-living & must search for food. http://poster.4teachers.org/view/poster.php?poster_id=37977 http://www.sealifeimages.net/hawaii/nudibranchs-flatworms/i-br9vmbh
Classifying Marine Animals Phyla of Worms Segmented worms (Annelida) - Most advanced of the worms & can be fairly large. - Round bodies that are elongated & divided internally & externally into repeating segments. - They have a body cavity, circulatory system with blood vessel, nerve cord, & entrance & exit to their digestive system. https://www.treknature.com/gallery/europe/greece/photo186150.htm http://www.divegallery.com/tubeworm.htm
Classifying Marine Animals Mollusks ( soft bodied ): Soft Bodies Protected by Shells Sometimes referred to as shellfish. Many have a mantle that secretes some kind of shell. Another distinctive characteristic is the muscular foot used to move.
Classifying Marine Animals Mollusks ( soft bodied ): Soft Bodies Protected by Shells Shelled mollusks are divided into those with - one shell (univalves) = snails - two shells (bivalves) = mussels, clams, & oysters Squid & octopus belong to a different group because they lack an external shell & have a well developed head.
Classifying Marine Animals Arthropods ( joint footed ): From Lobsters to Spiders Most numerous in the animal kingdom. Share some very distinct traits. - Jointed feet or legs. - Segmented bodies - hard outer shell (exoskeleton) Periodically shed their shells (molting) & secrete a new shell to accommodate growth.
Classifying Marine Animals Arthropods ( joint footed ): From Lobsters to Spiders Many are in the subgroup crustaceans - Use gills to breathe. - Have pairs of sensory appendages on their head (antennae). - Have paired limbs adapted to their specific function. (e.g. shrimp - walking, barnacle - filtering food, etc.) Widest variety of organisms in the ocean.

Classifying Marine Animals Echinoderms ( spiny skinned ) They have spiny, bumpy external cover. Radial symmetry (circular design) with five body parts.. Endoskeleton (test) - Plates or bumps of calcium carbonate. Have numerous tube feet. - Enables them to crawl slowly. - Also function in sensing their surrounding & in feeding.
Chordata Classifying Marine Animals All have the following traits at some point during development even if not apparent as adults. - Notochord, thin flexible rod to support their body. - Nerve cord running down their back. - gill slits; respiration for fish & develop into pharyngeal arches aiding in circulation for reptiles, birds, & mammals. - E.g. Humans have gil slits visible only in the embryonic stage.
Chordata Classifying Marine Animals All lower chordates are marine animals. More advanced chordates belong to subphyla vertebrata; have a backbone & are divided into five groups: - Fish - Amphibians - Reptiles - Birds - Mammals https://quantumbiologist.wordpress.com/2011/06/22/v-for-vanadium/ https://www.montereybayaquarium.org/animal-guide/fishes/rockfish
Classifying Marine Animals Chordata Fish = three types are jawless, cartilaginous, & bony Amphibians = live in both water & land Reptiles = adapted to living on the land Birds = have wings Mammals = largest creatures on earth
