Protection

4.

Match each eye adaptation to its purpose.

Draggable itemarrow_right_altCorresponding Item
Large eyes
arrow_right_alt
Uses eyes to see food
Small eyes
arrow_right_alt
Likely feeds off the bottom and relies on barbells/whiskers to detect food

Match each mouth adaptation to its purpose.
Very small mouth
Feeds throughout the water
No teeth
"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
Terminal (at the end of the snout)
Feeds on other (and bigger) fish
Very Large mouth
Grasps its prey
Angled upward/longer lower jaw
spears food
Strong jaws and well-developed teeth
Eats Plankton
Sword on front upper jaw
Swallow prey whole, shrimp, crabs, small fish
Duckbill Jaw
Eats small food like Zooplankton
Lies flat on bottom of water
Eyes on top of head
sits on bottom and looks up
Match each body adaptation to its purpose.
Non- Venomous and Venomous Spines
Protection from predators
Extra fat in cell membrane
Can look like a plant or a venomous organism to avoid predators
Bioluminescence
Attracts mates or prey in darker waters
Efficient Enzymes
Navigation, prey location, and communication. Some can produce strong electric fields to stun potential prey.
Slower Metabolism
Can poison predators, so predators stay away
Mimicry
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 the body shape to the type of swimmer.
hump backed
Horizontal disk, flat from top to bottom
Round Body
Triangle shaped
Oval, very Long, eel like, body
Fusiform, torpedo shaped body
Thin side to side, shorter, disk shaped
Rounder back, flat belly
Horse shaped
Oval, Long body
Box Shaped
Slow swimmer
Rests on the bottom
Open water swimmer
Fast swimmer/stable in fast water/Agile
Hides in weeds for protection or to ambush prey
Horizontal or Vertical Stripes
Hides in rocks or on the bottom
Uniform, no markings
Less visible to predators above it, predators have difficulty seeing it from above
Light colored belly
Less visible to predators below it, predators have difficulty seeing it from below
Protected by adults
Floating eggs
Dispersed in high numbers
Egg deposited in nests
Stable until hatching
Egg deposited in bottom
Few babies, but high survival rate
Rounded lobed caudal fin
Strong, fast continuous swimmer
Large Torked or Tri-lobe caudal fin
able to swim in and around cracks and crevices.
Double truncated caudal fin
Fastest swimming fish and maintain a rapid speed for long durations
Truncated/Straight caudal fin
Strong, but slow, swimmers and can do quick burst of speed
Continuous caudal fin with dorsal and pelvic fins
Strong, slow swimmers
Lunate/Concave 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.
Spines on fins
For protection or to stiffen fins for swimming
Wing-like pectoral fins
Bottom Dwellers
Finlets
Open water swimmers
Dorsal fin acts like a lure
Able to provide an upward lift, can jump out of water
Strong pectoral fins
Gives superior control in the water, moving forward and backward with a minimum of wasted energy.
Anal fin attached 2/3 length of body and fused with caudal fin
To attract prey
Large Pelvic fins
a cooling and heating system after or before high-speed bursts.
Small pelvic fins
To improve swimming speed
High dorsal fin that covers most of back
To walk along the bottom of the ocean
