If fish and coral larvae opt to settle in coral-dominated areas instead of the degraded, seaweed-dominated reefs ecologists' efforts to restore reefs could become complicated.

With a series of experiments, a team of researchers led by Danielle Dixson from Georgia Institute of Technologyc ompared water from marine protected areas, where fishing is restricted and corals abound, to water from non-protected areas, where seaweed has largely replaced both corals and fish on the reefs.

Toadfish loud sex call keep Californians awake at night

9 years ago By Chief minion

Toadfish is the common name for a variety of species from several different families of fish which have a toad-like appearance in common. They are known for their ability to produce sound with their swim bladders.

The endless motor-like sounds are produced by their strong muscles pressing against their balloon-like bladders. They hit the bladder about 6,000 times a minute -- twice the speed of a hummingbird's wings -- and do it during a mating season that usually starts in May and ends in September. The loud hum can last for more than an hour at a time.

Whale shark aggregation found in the Red Sea

A multinational team of researcher utilized three types of satellite transmitting tags to track the movements of 47 whale sharks from 2009 through 2011. The tags, which are placed just below the dorsal fins, measure temperature, depth, and light levels of the waters the fish swim in. After several months, the tags pop off, float to the surface and beam data via the ARGO satellite system back to computers on shore.
