Scientists reveal which snakes have sharpest teeth


Monash University
New research is using high-resolution 3D scanning to reveal patterns in the design of snake fangs, showing that these needle-like teeth are shaped to match the snake’s preferred prey.
Venomous snakes are notorious for their deadly needle-like fangs. These unusual teeth have a tunnel on the inside that runs down the entire length, just like a medical syringe. The venom is thus truly injected when snakes bite into their victims.
But before this venom can be delivered, these fangs first have to puncture their prey. This requires them to be sharp, but not so pointed that they become fragile and break when the tip hits the surface of their food. This is important because not all foods are the same: while rats and mice have soft skin, lizards have scales, and crabs have hard shells. ....

How seals adapted to move through water


How seals adapted to move through water
Collaboration of zoologists and engineers solves seal “evolutionary riddle”.
Have you ever wondered how seals learned to perform their skilled underwater acrobatics?
Zoologist David Hocking, formerly of Monash University and now curator of vertebrate zoology and palaeontology at the Tasmanian Museum and Art Gallery, did, and says he has now helped “to solve an evolutionary riddle at the heart of seal evolution”.
Seals and sea lions propel themselves through the water to catch their prey – but true seals (otariids) generally use their front flippers while eared seals (phocids) use their back feet, and the other limbs are used for steering. ....
