Madagascar Huntsman Spiders stitch leaves together with silk

Madagascar Huntsman spiders stitch leaves together with silk to trap tree frogs. 

Researchers in a vanilla plantation in north-east Madagascar in 2017 found an unsual Huntsman Spider while conducting wildlife surveys. While surveying birds, Dominic Martin at the University of Goettingen in Germany noticed a Huntsman Spider (Damastes sp.) eating a tree frog (Heterixalus andrakata).

His colleague, Thio Fulgence, at the University of Antananarivo in Madagascar, who was surveying reptiles and amphibians in the plantations, noticed that the spider was sitting between two leaves that it had stitched together with its silk to form a type of envelope.

What is an animal’s Arc of Vision?

What is an animal’s Arc of Vision? 

An Arc of Vision (AoV) is also known as the Field of View (FoV) or the Field of Vision (FoV) or the Visual Field. 

It is the view that an animal can see when its head, and the eye, are still. Can it see all around it – on all sides – or can it only see what is in front of it?

Monocular vision is what can be seen with one eye, and binocular vision is what can be seen with two eyes.

RESEARCH: Fish are getting smaller as sea temperatures rise

Scientists think that adult fish are getting smaller as sea temperatures rise. 

Research scientists have been studying the size of fish in the ocean over the past 50 years, since 1970, and they think that they are shrinking in size due to warmer oceans.

At the University of Aberdeen in the United Kingdom, Idongesit Ikpewe and his colleagues have found that warmer seas are linked to changes in fish size. They looked at trends in four commercially fished species: cod, haddock, whiting, and saithe. They researched these fish in two locations: (1) the North Sea and (2) in the waters of Scotland.
