The “Albino” Trigger

As far as aberrant pigmentation in marine fish go, this trigger recently up for sale by justrarefish.com is one of the more unique specimens we've come across. While aberrant tangs and angelfish are rare, we see a few examples every year. But triggers? Not so much.

Study Suggests Overfishing of Sharks Is Harming Coral Reefs

We tend to view the foundation of the food pyramid from the base up, but overfishing fish at the very top can create serious imbalances at the bottom of the food chain as well. Researchers have found that overfishing apex predators like reef sharks causes a reduction in the number of herbivores (e.g. parrotfish, tangs, blennies) that keep reefs healthy by grazing algae. Why does this happen? The reduction of apex predators results in an increase in mid-level predators such as snappers and groupers who hunt herbivores.
