Sawfishes can slash from side to side with the rostrum to stun, impale or even cut prey fishes in half. The rostrum can also pin fishes to the substrate where they are ingested.

It was a 'four day week' this week so we are down an image or two from normal. Despite that, there are still some great additions. The Warty Anglerfish is an amazing looking fish and the Red Indian Fish has always been one of my favourites. This week's blog post, 'Grey Carpetshark senses' is certainly worth a look. Thank you as always to our contributors.
In this movie, Ryan Kempster, shark biologist at the University of Western Australia, talks about the senses and survival strategy of the Grey Carpetshark, Chiloscyllium punctatum. Other common names for the species include the Bamboo Shark and Brown-banded Catshark.
