Introduced armored suckermouth catfishes (plecos to aquarists) are scrubbing Floridian manatees of their algae growing on their skin. What impact this may have on the manatees is unknown; it could be possible the loss of algae renders the manatees less capable of thermoregulating and it’s also possible the manatees needlessly expend energy avoiding the catfish.
It is somewhat compelling to get yourself to watch such a monumental piece of pure advertisement, but this one from ADA is still worth a watch. The movie shows the products, but also somewhat the works of Aqua Design Amano (ADA), a premier aquascaping manufacturer from Japan. ADA is led by a guy called Takashi Amano, who is widely considered to be the father of the contemporary style of planted aquariums. Give it a try.
"Slow" marine animals show their secret life under high magnification. Corals and sponges are very mobile creatures, but their motion is only detectable at different time scales compared to ours and requires time lapses to be seen. These animals build coral reefs and play crucial roles in the biosphere, yet we know almost nothing about their daily lives.Watch the Video
