Competition
1. Below are two types of organisms that compete. Explain what each is fighting for and the strategies employed to dominate.
a. Corals- Compete for Sunlight
i. Staghorn coral – grow fast and rise above the competition ii. Adjoining corals – certian corals are able to kill certian corals, so must be carful about ones neighbors. iii. Explain the concept of "demilitarized zone" or "no man’s land" - zones where competing corals have met, done battle, and withdrawn
b. Fish competition
i. Grunts – threaten with open, reddish mouths when competing ii. Groupers – stand their group agianst intrustion iii. Surgeonfish - use razor sharp spines in fighting
2. Creative Protection-Simple …show more content…
Sponge Crab - use inedible sponge to cover its body
b. Define the term, Nematocyst - tiny capsules in which threads are coiled, ready for action.
c. Explain how Cnidarian nematocysts work to catch prey and ward off predators
i. Mechanism -nematocysts are sensitive to both chemicals and to touch. ii. Sequence of events - the harpoons remain attach to the tentacle, so the prey does not run of before the venom works. iii. How and what role does hydraulic pressure play? - The nematocyst's capsule is flooded with water, this pressure change force the harpoon out into the prey. iv. What are the different effects seen on nematocysts? - can cause paralysis, or even death.
d. Explain the relationship of the organisms below with anemones.
i. Pederson’s Shrimp – live in caribbean corkscrew anemones. They wave their antennae to attract attention. They use the anemones as a home and for protection. ii. Red snapping shrimp - uses the anemone as a home and protection. When a intruder approaches the shrimp uses its large pincer to create a loud snap the can stun the intruder.
3. Creative Protection-Complex Harpooners
a. Define Conotoxins and explain how they may benefit humans - is the name of the chemicals produced by
