Animal Adaptations in Aquatic Environments

Predator Adaptations

• Sharp Teeth/Claws: Predators like sharks use sharp teeth to cut through prey.
• Camouflage: Animals like octopuses change color and texture to hide from prey or predators.
• Speed and Agility: Dolphins swim fast to catch fish or escape danger.
• Keen Senses: Sharks have a strong sense of smell to track prey.

Prey Adaptations

• Camouflage: Flounders blend into the sea floor to avoid predators.
• Speed and Hiding: Sea turtles swim away quickly and hide in shells.
• Schooling Behavior: Fish swim in schools to confuse predators.
• Defensive Structures: Sea urchins have spiny bodies to deter predators.

Trophic Levels

• Primary Producers: e.g., phytoplankton, seaweed (capture sun's energy).
• Herbivorous Consumers: e.g., zooplankton, cockles.
• 1st Level Carnivorous Consumers: e.g., juvenile fish stages, jellyfish, small fish, crustaceans, sea stars.
• 2nd Level Carnivorous Consumers: e.g., larger fish.
• 3rd Level Carnivorous Consumers: e.g., squid.
• Top Carnivores: e.g., shark, dolphin, albatross (experience heat energy loss).
