When friendship dies away, I think the best thing you can do is to think of that person as someone who accompanied you for a part of your life. They helped you, they were here at a certain time and added something to your life. They were not meant to stay for longer than that but celebrate the short moment and let them go. They were on your road to help you at one moment of your life. You will find other friends who will follow you and walk at your side forever. Some friendships die away but that doesn’t mean they didn’t hugely touched you or have an impact on your life.

Cherish that.

October 8: World Octopus Day

October 8 is World Octopus Day

Octopus facts:

Studies have shown that octopuses learn easily, including learning by observation of another octopus.
They can solve problems, as when they remove a plug or unscrew a lid to get prey from a container.

They are the first invertebrates to be seen using tools, such as using coconut shells to hide from potential predators and using rocks and jets of water in a way that could be classified as tool use. 

Common octopuses will collect crustacean shells and other objects to construct fortresses, or “gardens,” around their lairs. Other octopuses carry shells for protection. 

They have been found to play with a ‘toy’ and to have individual responses and individual temperaments, with some scientists believing they have individual personalities.
All octopuses are venomous, but only the small blue-ringed octopuses are known to be deadly to humans.

AS BIRDS SOME REEF FISHES SING A DAWN CHORUS

But a creepy chorus. Australian scientists have found evidence that certain species of fish actually sing together, in a chorus, each day at dawn and dusk.  The results are published in the Journal Bioacoustic.

Researchers recorded vocalization of fish over an 18-month period in the coastal waters off Port Headland in Western Australia, and what they found were seven distinct fish choruses, happening at dawn and at dusk

Sound plays an important role in various behavioural functions and life stages of fish, such as spawning, feeding, territorial disputes or distress. Noctural fishes use calls to stay together when they hunt, while fish that are active during the day use sound to defend their territory.

Cataloguing the acoustic characteristics and temporal patterns of choruses and their locations is important, can provide significant information for long-term monitoring of vocal fishes and their ecosystems. A silent aquatic environment means ecosystemic problems such as lower species abundance and absence of fish.
