This little nifty line cutter we actually got demonstrated for us, and it convincingly sliced though even thick lines with ease and simple movement.

A new study by researchers at the ARC Centre of Excellence for Coral Reef Studies has found weed-eaters like parrotfish and surgeonfish can only keep coral reefs clear of weed up to a point. After the weeds reach a certain density, they take over entirely and the coral is lost.
For some years, researchers have pinned their hopes on the ability of weed-eating fish to keep the weeds at bay while the corals recover following a major setback like bleaching, a dump of sediment from the land, or a violent cyclone.
Noise pollution in the oceans has been shown to cause physical and behavioral changes in marine life, especially in dolphins and whales, which rely on sound for daily activities. However, low frequency sound produced by large scale, offshore activities is also suspected to have the capacity to cause harm to other marine life as well.
Spanish researchers examining the effects of ocean noise pollution on different species of cephalopods have shown that exposure to low frequency sound can cause lesion that has been linked to squid deaths in the wild.
