The blue-throated fairy wrasse: a new species

By on

At a cursory glance, we tend to lump similar-looking reef fish into a monolithic species and chalk up differences as variants. But upon closer examination, we are finding sufficient distinction to satisfy the description of a new species. Cirrhilabrus cyanogularis is a case in point.

Hermit crabs that blanket themselves with anemones instead of shells

By on

Just about every hermit crab species seeks mobile shelter within empty shells. Not blanket-hermit crabs.

Forecasting the fate of corals

By on

Many of us concerned about climate change's effect on corals have wondered how long corals might survive rising ocean temperatures. Researchers studying Acropora millepora believe this SPS can adapt to 100 to 250 years of rising sea temperatures due to how common they are. Common = genetic diversity = adaption. Rarer corals are not likely to adapt as well.

Perhaps it's time to hold off buying Aussie fish

By on

The Great Barrier Reef has been hit by two consecutive years of devastating severe bleaching events. A new study shows that not only are corals being wiped out but so are reef fishes that rely on corals for food and shelter. Australia's fish populations could benefit from any relief in pressure.
