  5. Harmful Algal Blooms • Algal blooms occur naturally and frequently • Not all are harmful • Fresh and salt water • Can contaminate seafood and result in fish kills

  6. Ciguatera Fish Poisoning (CFP) • Nausea, vomiting, diarrhea, numbness of the arms, legs, and mouth, and sometimes the reversal of temperature sensation. • Rarely fatal, and gastrointestinal symptoms may last for a few days

  7. Paralytic Shellfish Poisoning (PSP) • Numbness of the lips and mouth, nausea and vomiting, giddiness, drowsiness, and fever WHOI

  8. Amnesic Shellfish Poisoning (ASP) • Vomiting, stomach cramps, diarrhea, seizures, severe headaches, loss of memory, and difficulty breathing

  9. Diarrhetic Shellfish Poisoning (DSP) • Diarrhea, vomiting, and stomach pain • No outbreaks reported in U.S. waters NOAA

  10. Neurotoxic Shellfish Poisoning (NSP) • Nausea, vomiting, diarrhea, numbness of the arms, legs, and mouth • Symptoms similar to CFP • “Red tide” David Patterson and Bob Andersen

  12. Spiny Dogfish • Vision and fluid formation in the eye NOAA

  13. Horseshoe Crab • Test for impurities in some medical products NOAA

  14. Toadfish • Inner ear almost identical to humans • Balance disorders
