... Fresh water corals, fish, odd things...

A lot of evolution can happen in 25 million years I guess.

Er...
did those divers go to 600 feet to install those cams?

Wondered that myself. The divers, and coral - which mighty actually be sponge - look to be illuminated from surface light.
It's pretty bright for 600 feet.
OTOH the first two like cameras look to use artificial lighting. They may be the deep ones.

The text mentions cameras which operated at 5 meters, as well as at 200 meters. The pictures with coral are more likely from the 5 meter deep camera, surely? After all, corals are photosynthetic...

No they are not. Only their symbionts are. And there are numerous species that lack symbionts.

Like the deep water corals...

It's just in photic zones symbiont bearing corals rapidly outgrow the strictly carnivorous ones. And even most of the symbiont bearing corals practice carnivory at night.
