Study Notes
Adaptations for Swimming in Marine Organisms
- Swimming mechanisms of marine organisms include muscular contractions, water entering and forced out of their cavities
- Medusas, like Portuguese man-of-war, use a sail-like structure for directional movement
- Different swimming organisms include fish, squid, sea turtles, and marine mammals
- Flying squids trap water in their mantle cavity for propulsion
- Fish use different fin designs for stabilization, steering, balance, and thrust
- Different swimming motions include S-shaped and L-shaped, used by various organisms
- Predatory fish have different muscle tissue colors for different swimming strategies
- Swimming speed is generally proportional to the size of the fish
- Cold-blooded fish are typically not fast swimmers, while warm-blooded fish are more efficient
- Deepwater nekton have adapted to perpetual darkness by using bioluminescence to attract prey and mates
- Deepwater nekton have large, sensitive eyes, sharp teeth, expandable jaws, and a large belly for scarce food
- Schooling is an adaptation used by smaller fish to confuse predators and appear larger in numbers
