How do red tides affect manatees?

How do red tides affect manatees?

If manatees pass through a bloom, they can inhale airborne brevetoxins released from the red tide cells. When manatees are poisoned by red tide, they suffer symptoms similar to a seizure and lose control of motor function. Ultimately, they die by drowning as they inadvertently inhale water during a convulsive episode.

How do algal blooms affect manatees?
