hello have you ever, just been, really bothering a small amphibian all over, and they decide they have had enough of it
the unken reflex is a defensive posture that a handful of salamanders, toads and frogs do when they feel threatened, and it involves curling right up and showing off their bright underbellies ( which usually, BUT NOT ALWAYS, means the animal in question is POISONOUS and you shouldnt eat this thing !!! dont eat this !!!!! )
the above three are rough skinned newts and a california newt, but the reflex itself is named after the fire-belled toads ( whose genus is unke in german ) where it shows up a little differently
(note the covered eyes ! )
while displaying, the animal in question gulps down a bunch of air, makes themselves as still as possible, and also releases toxins from their skin if they got em – but not all amphibians with the unken reflex have poison, and some of the poison ones dont have bright underbellies, and some dont curl up all the way while theyre doing it – its a mixed bag of postures. thats how it is sometimes
INCT CENBAM (Centro de Estudos da Biodiversidade Amazônica) (Centre for Amazonian Biodivesity Studies) was created in 2009 with the principle objective of consolidating outputs based on firm scientific knowledge that start with biodiversity studies and end with information, products and processes that are useful to specific users in the short, medium and long-term. It coordinates a network of Amazonian and extra-Amazonian institutions involved in biodiversity studies.
Programa de Pesquisa em Biodiversidade (PPBio) was created in 2004 with the aims of furthering biodiversity studies in Brazil, decentralizing scientific production from already-developed academic centers, integrating research activities and disseminating results across a variety of purposes, including environmental management and education.
The researchers used
high-speed photography and an instrument called a Rheometer to analyze frog saliva under prey-capturing
conditions. The scientists think frog tongues could one day
help engineers design reversible soft adhesives that could work at high speeds.
