Overview

• Oceans Are Diverse Habitats (e.g. coral reefs)
• Oceans Diversity Mediated by Chemistry (i.e.
  biologically active compounds)
• Diversity of Compounds from Marine Animals are
  Rich Source of Drugs

3
Ocean Habitats are Diverse
4
Freshwater Habitats
Lakes and Ponds Rivers and Streams
Wetlands Swamps Bogs Fens etc.
also estuarine (i.e. brackish) habitats!
5
Coral Reefs
23.5 N
23.5 S
255330 sq. km. lt 0.25 of the area of the ocean
Coral Reefs 50 m deep (ocean is 3.8 km deep)
6
Coral reefs are among the most complex habitats
on Earth
25 of oceans fish
1 million species identified
estimated 8 million to go!
7
Why are coral reefs so complex
Shore
Deep Water
Colonization
High oxygen
Architecture
8
Many of the interactions in the coral reef are
based on CHEMISTRY
9
Biologically Active Compounds
Toxins (Toxicology)
Drugs (Pharmacology)
10
Drugs from the Sea Marine Animals
Percent Compounds Tested by NCI with Significant
Cytotoxicity
11
Vast Majority of Drugs from Marine Invertebrates
Microorganisms
Green Algae
Sponges
Brown Algae
Red Algae
Tunicates
Echinoderms
Mollusca
Cnidarians (e.g. Corals)
12
Why so many biologically active compounds from
invertebrates
