classification system?

• Carolus Linnaeus

How do you correctly write the binomial nomenclature of an

organism?

Classifying Marine AnimalsPhyla 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 AnimalsPhyla 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.

Phyla of Worms

• Flatworms (Platyhelminthes)

Classifying Marine AnimalsPhyla 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.

Classifying Marine AnimalsMollusks (“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 AnimalsMollusks (“soft bodied”): Soft Bodies

• Shelled mollusks are divided into

- 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.

Mollusks (“soft bodied”): Soft Bodies Protected by Shells

• Shelled mollusks are divided into those with…

Classifying Marine AnimalsArthropods (“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 AnimalsArthropods (“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.

Log into goggle classroom & complete the formative

assessment “Unit_14 Classifying Marine Animals Formative

Assessment 1” on your own.

• No notes

• This will not affect your grade, it is a measure of what you

currently know about the Nature of Seawater.

• This will inform you & I about what areas we need to focus on

Classifying Marine AnimalsEchinoderms (“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.

Classifying Marine AnimalsChordata

• 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.

Classifying Marine AnimalsChordata

• 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

Classifying Marine AnimalsChordata

• 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
