Sea Turtles Get Caught In The Bycatch

April 28, 2013

(OCEANS) In a new study, Bryan Wallace and a team of researchers illustrate the relationship between sea turtle bycatch, (unwanted animals which are caught by fishing boats then discarded) and small-scale fisheries. Although there is little research backing bycatch and mortality rates in terms of endangered species like marine turtles, Wallace, in his research, learned that on average, the hardest places to be a sea turtle were in the East Pacific, Northwest, Southwest Atlantic, and Mediterranean. With such a vast number of sea turtles being killed in the bycatch of small-scale fisheries, it is critical for these small-scale fisheries to become a sustainable business.

Dolphins, The Ultimate Sleep-Swimmers

April 26, 2013

(OCEANS) The things that keep most of us up at night, may have dolphins sleeping easy. But interestingly enough, our marine mammal friends might not need it. Dolphins have a unique ability to sleep with only half of their brains, keeping the other half alert while they rest. This function allows dolphins to avoid predators, and surface for air, while they remain at rest. Continue reading below in order to find out more about this interesting study. — Global Animal

Are Jellyfish Taking Over The Oceans?

January 2, 2013

(OCEANS) Despite popular belief that these gelatinous sea creatures are taking over the world’s oceans, new studies suggests that there is in fact a 20-year cycle which directly correlates to the abundance of jellyfish in various parts of the world. According to researchers from the Global Jellyfish Group, this current rise in the cycle may have created the perception of a global swell in jellyfish. In fact, multidecadal cycles are common in nature, whether in growth patterns and populations in organisms or physical circumstances such as the oxygen concentration of the oceans. Read more about the recent study pertaining to the rise-and-fall cycle of these populous sea organisms. — Global Animal

The Mystery Behind Dolphin Deaths

April 11, 2012

(DOLPHIN SCIENCE) Over the past two years, different species of dolphins all over the world have died in mass numbers, and scientists have no idea why. The Gulf of Mexico, Cape Cod, Brazil and Peru have all reported hundreds of these marine mammals dying from disease, and from beaching themselves. Human interference, pollution, algae blooms, bacteria, oil, and fishing practices could all be culprits, although the evidence gathered so far leads scientists to no conclusive explanation. While populations of dolphins in one area are dying out, other areas studied containing the same species appear healthy, which is why researchers are unsure about what’s really going on in our oceans. Read on for the details about this dolphin crisis. — Global Animal
