Here is a nice collection of plankton underwater shot by Dr. Evan D’alessandro while conducting research offshore Miami
The Portuguese Man of War or Physalia is a siphonophore floating at the surface of the ocean like a drifting balloon with deadly tentacles waiting to capture careless preys. Its body looks like a sail that catches the ocean wind to propel itself.
The Portuguese Man of War Fish or Nomeid seems to be immune to the powerful sting of the Physalia. It is actually a very agile swimmer that can avoid the stinging tentacles.It uses this deadly siphonophore for shelter against predators and can also feed on some of the smaller tentacles that do not seems to have a strong sting.
Our favorite, the Venus Belt! Nice to see this one in color!
If you click on the this amazing picture you will see a small fish larvae seeking shelter among the salps. very neat!
Beautiful bloom of lobate ctenohphores. The wall of death some smaller plankters:)
