It is important that conservation planning considers neglected taxa, supported by scientific studies. Massive glaciers retreated, leaving a carved-out landscape behind. overfishing is the main driver of mass species extinction in the oceans. The United States Association of Reptile Keepers, which advocates for responsible private ownership and trade in reptiles and amphibians, said in a statement that addressing reductions in wild populations by limiting captive breeding and legal trade is counterproductive.

Overall, we found that Africa and the Caribbean constitute the greatest risk hot spots. The decrease in toxicity occurred with a two-fold and four-foldincrease in calcium, but there was no observable decrease with an eight-fold increase,suggesting that there is a threshold in the effect of calcium on the toxicity of saline solution. Dr Doherty said the total number caught in the test period on lines with and without SharkGuard was low and so further trials are needed.
