  1. Adaptations

  2. Protection from predationby: • Camouflage • Venom, poison, stinging cells • Armor • Specialized appendages • Symbiotic relationships • Detection

  3. Camouflage • Camouflageis a method of concealment that allows an otherwise visible animal to remain unnoticed by blending with its environment.

  4. Mimic Octopus

  5. Venom, poison, stinging cells • Venom is the general term referring to any variety of toxins used by certain types of animals that inject it into their victims by the means of a bite or a sting. • Poisons are substances that cause disturbances to organisms, usually by chemical reaction or other activity on the molecular scale, when a sufficient quantity is absorbed by an organism. • Stinging cells provides a means for them (coral, sea anemones, hydrae, jellyfish, etc.) to catch prey and defend themselves from predators.

  6. Lionfish Sting, Anemone 0r Box Jellyfish Sting.

  7. Armor • Ridged outer layer, usually made from chiten, or bone. kitien is the same material as human fingernails. Must molt to grow. • Fish scales, lobster, and shrimp shells are made of chiten. • Turtle shells are made of bone. • Other armor would be seashells. Made from calcium carbonate.

  8. Remember, chiten not kitten.

  9. Specialized appendages • Attachment on remora • Suckers on octopi, squid and cuttlefish • Claws • Fins, flippers for mammals • Tentacles

  10. Symbiotic relationships • Remora and shark • Cleaner fish and other fish • Clown fish and anemone

  11. Detection • Lateral line: detects pressure difference • Eyesight: most fish cannot dilate or contract pupil for differing light. Sharks can. • Ampule of Lorenzini: electroreceptors. Mostly in cartilaginous fish. Sharks and rays. Can detect the electrical impulse used to contract muscles. • Smell: all fish can smell. Some better than others. Tentacles can also detect smells.

  12. Detection
