100

The oceanic crust is primarily made of this type of rock

Basalt

100

Organisms evolve soft, squishy bodies in response to this condition of the deep sea 

Pressure

100

Cephalization is a key feature of this class of mollusks 

Cephalopods 

100
Choanocytes, the cells that generate internal water currents and catch  of a sponge also go by this name

Collar cells

100

Lampreys and Hagfish lack this feature, putting them into the group known as "Agnatha"

Jaws

200

Species who live up in the open water column 

Pelagic

200

Organisms in the deep sea depend on these large deliveries of nutrients from the surface to sustain themselves

Whale Falls

200

Echinoderms display this type of symmetry in their body plan

Pentamerous Radial Symmetry

200

Sponges have this type of symmetry

Asymmetry

200

Lampreys and Great White Sharks share this in common

Cartilaginous Skeleton

300

The section of the continental crust that extends out into the ocean

Continental Shelf

300

The depth of the deep sea and the turbid (murky) waters of estuaries, mean that organisms in these environments must adapt to a lack of this environmental condition

Light 

300

Snails belong to this class of Mollusks 

Gastropoda 

300

These two body plans are displayed by Cnidarians at some point in their life cycle

Polyp and Medusa

300

The difference between rays and skates

Rays have stingers (venomous barbs) skates do not

400

An immobile benthic organism

Sessile

400

Due to the absence of sunlight, this process replaces photosynthesis in the deep sea

Chemosynthesis

400

Echinoderms of the class Asteroidea are more commonly known as

Sea Stars or Starfish

400

Jellyfish digest their prey in this body chamber

Gastrovascular Cavity

400

Sharks have this many gills located on this area of their bodies (give two anatomical terms of direction)

5-7, Lateral, and Cranial/Anterior

500

The 5 major ocean basins of the world 

Pacific, Atlantic, Indian, Southern, Arctic


500

These estuarine organisms deal with large swings in salinity by actively maintaining internal salt concentrations

Osmoregulators

500

Many Mollusks have a radula for eating, but all Mollusks share these three traits in common

Mantel, Foot, and Calcium Carbonate Shell

500

True jellyfish belong to this class of Cnidarian

Scyphozoa

500

This camouflage pattern, where the belly is lightly colored and the back is dark colored, is displayed by many fish including sharks

Dorsal Ventral Counter Shading
