Blue Whales Re-establish Former Migration Patterns
photo credit: Amnemona The planet’s largest animal may be returning to pre-whaling feeding grounds. Scientists have documented the first known migration of blue whales from the coast of California to areas off British Columbia and the Gulf of Alaska since the end of commercial whaling in 1965.

New Tech Can Monitor Vast Groups of Fish

New Tech Can Monitor Vast Groups of Fish
New technology is allowing researchers and conservationists to watch the movement of large groups of fish as they gather into shoals and later split up. Focusing on Atlantic herring, the scientists were, for the first time, able to observe the fish gather off Georges Bank near Cape Cod, Mass., where...

Captive Bred Black Tiger Prawns Lack Lust, ‘Prawnography’ Shows

Captive Bred Black Tiger Prawns Lack Lust, ‘Prawnography’ Shows
photo credit: Vincent Boiteau A researcher has studied hours of prawn "sex tapes" to find out why prawns bred in captivity did not go on to breed well. Life sciences researcher Gay Marsden, from Queensland University of Technology, spent two months filming what prawns got up to when the sun went down. "The...

Human-generated Sounds May Be Killing Fish
photo credit: pinhole (Mark) Anthropogenic, or human generated, sounds have the potential to significantly affect the lives of aquatic animals - from the individual animal's well-being, right through to its reproduction, migration and even survival of the species. According to a new study marine animals...

Scientists Find First Animal That Had Sex

Scientists Find First Animal That Had Sex
Remains of embryos entombed in their fish mothers' wombs for 380 million years have been found in fossils from an ancient rock outcrop in Western Australia. The finding is a big deal because it suggests that sex goes way back. The prehistoric fish, called placoderms, are found at the base of the vertebrate...

Shape-shifting Coral Evade Identification

Shape-shifting Coral Evade Identification
The evolutionary tendency of corals to alter their skeletal structure makes it difficult to assign them to different species. Researchers writing in the open access journal BMC Evolutionary Biology have used genetic markers to examine coral groupings and investigate how these markers relate to alterations...

Global Warming Threatens Antarctic Sea Life

Global Warming Threatens Antarctic Sea Life
Climate change is about to cause a major upheaval in the shallow marine waters of Antarctica. Predatory crabs are poised to return to warming Antarctic waters and disrupt the primeval marine communities. "Nowhere else than in these ecosystems do giant sea spiders and marine pillbugs share the ocean...
