2012年3月6日 · Here, we show that juvenile freshwater sawfish Pristis microdon are active predators that use their toothed rostrum — the saw — to both sense prey-simulating electric fields and capture prey. Prey encountered in the water column is attacked with lateral swipes of the saw that can stun and/or impale it.

2012年3月5日 · University of Queensland scientist Barbara Wueringer has been studying how the sawfish uses its saw and has found the North Queensland freshwater fish used its saw to impale prey on its...

Scientists have learned that the sawfish rostrum contains thousands of tiny sensors (known as ampullary pores) that can detect the invisible electric fields that surround living organisms. Using these special sensors on their saws, sawfish can locate fish swimming in the waters around them.

2012年3月5日 · Although all seven species of sawfish are nearly extinct, scientists have spent little time studying these vanishing species. However that is changing as a new study in Current Biology sheds light on the sawfishes’ most distinguishing feature: its long toothed snout, which gives the fish its name.

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. This movie clip shows a sawfish feeding.

2025年3月6日 · The sawfish swings its unusual tooth-lined snout from side to side to impale and stun its prey.

2025年1月14日 · Understanding sawfish anatomy provides insights into how these animals navigate their aquatic environments, hunt for prey, and interact within their ecosystems. Examining the various anatomical components of sawfish reveals a complex interplay of structures and systems that enable them to thrive in diverse habitats.
