They’re “gross and slimy and flaccid and wiggling.” But parasites can be just as important as more charismatic animals—and many may be on the verge of disappearing.

Where did Sharks evolve from? It's thought that they descended froma small leaf-shaped fish that had no eyes, fins or bones. These fish then evolved into the 2 main groups of fish seen today. Bony fish (Osteichthyes) and cartilaginous fish (Chondrichthyes – the sharks, skates, rays and ...
haveshifted their ranges by hundreds of kilometres. Other effects are more subtle. Oceanic low-oxygen zones are expanding because oxygen is less soluble in warm water. This is forcing species such as blue sharks to stay closer to the surface, making them more likely to be caught ...
In other words “As whale numbers diminished, concerns that whole species may become extinct eventually led to most whaling being banned by the International Whaling Commission in 1986. Although some populations have been able to bounce back, many species remain depleted and some are still in ...
“For our study, we measured body size, which is important because it interacts with how fast animals grow, how much food they need, how big their populations are, and how likely they are to become extinct.” Why Crocodiles Endure
he was invited to help assess the status of these animals. “As a scientist, I feel like we study the genomics, transcriptomics, and evolution of species,” Li explains. “On the other hand, we are seeing a lot of species going extinct. I wanted to apply my research results, skills, ...
000 links between the species. This gave researchers a better understanding of sharks and their significants as well as the consequences of human activity towards sharks. The over fishing of sharks is primarily attributed to shark finning; an inhumane activity that involves slicing off the shark’...
