The spectacular snouts of sawfish are revealed as complete hunting weapons, sensing prey and killing them.
The saws, which can grow more than a metre long in some species, have previously been identified as able to sense prey by their electric fields.
Now, researchers have filmed the fish impaling prey on the teeth of the saws.
They suggest in Current Biology that sawfish are more active hunters than previously thought, which could help in their much-needed MORE
Last week the European Parliament began its work on the Commission’s proposal to close major loopholes in the EU ban on shark finning submitted in the fall of 2011.
The European Commission has proposed ending special permits that allow fishermen to cut off shark fins at sea and land them separately from the bodies under a legal exemption to the overall EU requirement for landing sharks with their fins naturally attached.

Sharks are among the most threatened of marine species worldwide due to unsustainable overfishing. They are primarily killed for their fins to fuel the growing demand for shark fin soup, which is an Asia delicacy. A new study by University of Miami (UM) scientists in the journal Marine Drugs has discovered high concentrations of BMAA in shark fins, a neurotoxin linked to neurodegenerative diseases in humans including Alzheimer's and Lou Gehrig Disease (ALS).
Sharks are known for being ruthless, solitary predators, but scientists say the reality is the opposite.
A new study revealed that some sharks enjoy complex social lives that include longstanding relationships and teamwork.The study documents how one population of blacktip reef sharks is actually organized into four communities and two sub-communities.
The research found for the first time that adults of a reef-associated shark species form stable, long-term social bonds.

During 2011, Brendon Sing worked his way across Asia, speaking with international schools, national environmental conferences and learning institutes about the importance of shark species, why they’re in trouble and what we can do about it.
In October 2011, after visiting many schools in Bangkok and Thailand, Brendon Sing embarked in a UK Tour and launched his Shark Guardian campaign in the UK.
Project AWARE celebrates the recent shark finning ban for Belize, Costa Rica, Dominican Republic, El Salvador, Guatemala, Honduras, Nicaragua and Panama waters and also but also on all vessels that fly their flags.
Project AWARE welcomes the inclusion, for the first time, of species of sharks and rays in the Spanish List of Wild Species under Special Protection (Listado de Especies Silvestres en Régimen de Protección Especial, in Spanish).
On 23 February 2011, the Spanish Official State Gazette published Royal Decree Nº139/2011, developing the List of Wild Species under Special Protection and the Spanish Catalog of Threatened Species. MORE
