Match each mouth adaptation to its purpose.

Draggable item		Corresponding Item
Very small mouth		Feeds throughout the water
Duckbill Jaw		"Vacuums" up food off the bottom; eats aquatic insects, vegetation
Sucker - Shaped		Feeds on prey it sees above it or at surface of water ; small fish, aquatic insects
Strong jaws and well-developed teeth		Feeds on other (and bigger) fish
Angled upward/longer lower jaw		Grasps its prey
Sword on front upper jaw		spears food
Terminal (at the end of the snout)		Eats Plankton
Very Large mouth		Swallow prey whole, shrimp, crabs, small fish
No teeth		Eats small food like Zooplankton

Match each scale adaptation to its purpose.

Draggable item		Corresponding Item
Small or non-existent scales		Used for protection; speed not needed to catch food
Bony armored scales		Fish more streamlined and fast-moving to catch prey
Large scales		Protection

Match each eye adaptation to its purpose.

Draggable item		Corresponding Item
Eyes on top of head		Uses eyes to see food
Small eyes		Likely feeds off the bottom and relies on barbells/whiskers to detect food
Large eyes		Lies flat on bottom of water
Eyes on same side of head		sits on bottom and looks up

Match each body adaptation to its purpose.

Draggable item		Corresponding Item
Extra fat in cell membrane		Protection from predators
Efficient Enzymes		Can look like a plant or a venomous organism to avoid predators
Bioluminescence		Attracts mates or prey in darker waters
Mimicry		Navigation, prey location, and communication. Some can produce strong electric fields to stun potential prey.
Non- Venomous and Venomous Spines		Can poison predators, so predators stay away
Slower Metabolism		Help speed up chemical reactions in the body in very cold waters
Poison skin		Less energy needed in very cold waters
Electric Organs		Insulation to prevent cells from freezing

Match each color adaptation to its purpose.

Draggable item		Corresponding Item
Horizontal or Vertical Stripes		Swims in open water
Light colored belly		Hides in weeds for protection or to ambush prey
Dark on top		Hides in rocks or on the bottom
Uniform, no markings		Less visible to predators above it, predators have difficulty seeing it from above
Mottled (a lot of pattern)		Less visible to predators below it, predators have difficulty seeing it from below

Match each reproductive adaptation to its purpose.

Draggable item		Corresponding Item
Egg deposited in bottom		hidden from predators
Egg deposited in nests		Protected by adults
Floating eggs		Dispersed in high numbers
Eggs attached to vegetation or rocks		Stable until hatching
Live bearers		Few babies, but high survival rate

Match each caudal fin adaptation to its purpose.

Draggable item		Corresponding Item
Truncated/Straight caudal fin		Strong, fast continuous swimmer
Double truncated caudal fin		able to swim in and around cracks and crevices.
Continuous caudal fin with dorsal and pelvic fins		Fastest swimming fish and maintain a rapid speed for long durations
Rounded lobed caudal fin		Strong, but slow, swimmers and can do quick burst of speed
Lunate/Concave caudal fin		Strong, slow swimmers
Large Torked or Tri-lobe caudal fin		Slow swimmer able to make sharp turns and to move in short bursts very fast from a standstill.

Match each other fin adaptation to its purpose.

Draggable item		Corresponding Item
High dorsal fin that covers most of back		For protection or to stiffen fins for swimming
Large Pelvic fins		Bottom Dwellers
Wing-like pectoral fins		Open water swimmers
Dorsal fin acts like a lure		Able to provide an upward lift, can jump out of water
Finlets		Gives superior control in the water, moving forward and backward with a minimum of wasted energy.
Spines on fins		To attract prey
Strong pectoral fins		a cooling and heating system after or before high-speed bursts.
Anal fin attached 2/3 length of body and fused with caudal fin		To improve swimming speed
Small pelvic fins		To walk along the bottom of the ocean
