By on

In 2013, our friends Ned and Anna DeLoach from blennywatcher.com shared with us some photos and a video of a potentially undescribed goby that lives exclusively inside lacy bryozoan colonies.

Feature Article: Mesophotic Coral Reefs: Life in the Deep

By Tim Wijgerde, Ph.D. on Apr 20, 2016 at 09:00 AM

We are all familiar with shallow coral reefs. Growing in warm, clear waters, these colorful ecosystems are easily accessible to divers and snorkelers alike. What is less known is that coral reefs extend into deeper waters, up to almost 200 meters. In these gloomy depths, corals have adapted to low light levels, cold water and elevated nutrients.

Towering cichlid aquascape

By on

The video is potato quality; the aquascape isn't. Most Malawi-style aquariums feature rocky substrate, but we dare say none quite like this. It's a great reminder that the aquascape doesn't always have to stop at the water line.

Sponges feed on coral mucus: Recycling waste on the reef

By Dr. Tim Wijgerde on Apr 11, 2016 at 09:00 AM

Marine biologists have found that sponges feed on coral mucus and convert part of it into detritus, making them efficient recyclers of biological waste on coral reefs. By transferring nutrients gained from coral mucus to other reef creatures in the form of shed tissue, sponges help feed the entire reef. This salvaging of animal waste by sponges—known as the sponge loop—helps explain why coral reefs can thrive in nutrient-poor tropical and cold waters. This insightful research was published recently in the open access journal Scientific Reports.
