THIS TRUMPETFISH IS USING ANOTHER FISH TO HIDE ITSELF WHEN HUNTING

And is working

Many animals use camouflage to avoid detection by others, yet even the most inconspicuous objects become detectable against the background when moving. One way to reduce detection while moving would be to ‘hide’ behind the movements of objects or other animals. Now, researchers have demonstrate experimentally, following field observations, that a trumpetfish (Aulostomus maculatus), a common marine predator, can conceal its approach from its prey by performing a behaviour known as ‘shadowing’, hiding behind, swimming closely next to another, larger and non-predatory fish.

Bicolor damselfish (Stegastes partitus), form highly localised colonies within structures on the reef substrate and exhibit characteristic anti-predatory responses, and are common meal for trumpetfish. Marine researchers working in the coral reefs off Curaçao, set up an underwater system to pull 3D-printed models of trumpetfish and the stoplight parrotfish (Sparisoma viride) being hand-reeled along a clear nylon line from one tripod to another, passing over the colony in the process, which was positioned halfway between the two. When these two 3D printed fishes were together, damselfish were quiet and show low antipredator responses.

-After field observation, marine researchers modeled the ‘shadowing’ behavior.

This is the only known example of a non-human animal using another as a form of concealment. According to researchers, this evidence reveal how predators can actively use another animal as a form of concealment to reduce detection by prey.

Hi! I know that it's important to socialize a puppy well with both people and other dogs. But I also know you shouldn't let a puppy in contact with other dogs or walk it in areas where other dogs go before they have been fully vaccinated to prevent diseases.

Does that mean the socialization starts only after they get all their vaccines? Or is there something I'm missing here? Also because I thought the early periods of a dog's life were especially important with regards to socialisation.

Thanks!

Question tax: who was the cutest puppy you've seen recently?

It is no longer recommended to wait to start socializing a puppy until after their vaccine series is done, but you do need to take precautions. The reason is that there is a critical socialization window right in the middle of this time that ends around 16 weeks. That doesn't mean they can't learn or be socialized outside of this time, but the experiences they have in this time period are very important for setting the stage to how they react to stimuli in the future. Puppies who are improperly or under socialized during this period are much more likely to have behavioral issues as adults.

It's important to also understand why we booster puppy vaccines so many times. Depending on what kind of vaccines or disease exposure the mother had, this same time period is when the maternal antibodies the puppy received will be lost. Those maternal antibodies protect the puppy, but also interfere with vaccine efficacy. We don't know when they will lose the protection from those maternal antibodies, so we booster through this period to make sure they are protected. So just having 1 or 2 vaccines wouldn't guarantee that the puppy was fully protected.

The compromise is to avoid areas of potentially higher risk during this time. Dog parks, for example, may be full of dogs of unknown vaccine status and could have wildlife around that may carry parvo, distemper, etc. However, a puppy class at a reputable training facility only allows vaccinated dogs and should have disinfection protocols in place to help reduce the risk of disease spread. Basically, your puppy doesn't need to live in a bubble during this period, but you should use reasonable caution. Also keep in mind that socialization doesn't necessarily mean meeting a bunch of people or dogs! It just means positive exposure. Sitting out in your yard and practicing appropriate reactions to strange dogs walking by is socialization. Playing videos with thunder, fireworks, etc and getting the puppy used to it is socialization. Getting used to the car, medical handling, grooming, strangers coming in the house, all of that is part of socialization.

I tried to think of the cutest puppy I've seen but I'm going to be lame and say they're all cute cuz I keep changing my mind!

Hate is not inborn; it has to be constantly cultivated, to be brought into being, in conflict with more or less recognized guilt complexes. Hate demands existence and he who hates has to show his hate in appropriate actions and behavior; in a sense, he has to become hate.

BRAINLESS BOX JELLIES CAN LEARN BY EXPERIENCE

Mangrove box jellyfish (Tripedalia cystophora) is a small species of box jellyfish, native to the Caribbean Sea and the Central Indo-Pacific, presenting a simple nervous system. But despite tiny, researchers have demonstrated present the ability to learn by association. Although has no central brain, and being the size of the finger-tip, this box jelly can be trained to associate the sensation of bumping into something with a visual cue, and to use the information to avoid future collisions.

In the wild, the Mangrove box jellyfish forage for tiny crustaceans between the roots of mangroves. To mimic this environment, researchers placed the box jellies in cylindrical tanks that had either black and white or grey and white vertical stripes on the walls. To the jellyfish, the dark stripes looked like mangrove roots in either clear or murky water. In the ‘murky water’ tanks, the jellyfish bumped into the wall because their visual system couldn’t detect the grey stripes very clearly. But after a few minutes, they learnt to adjust their behaviour, pulsing rapidly to swim away from the wall when they got too close, this state learning is based on the combination of visual and mechanical stimuli in simple animals with no brain.

The learning process, in difference with vertebrate animals, doesnt occurs in a central neuronal organs, but instead in a small organs named rhopalial nervous system, which act as learning center, in which the jelly combines visual and mechanical stimuli during operant conditioning.

“When I was playing Hamlet, a guy took out his laptop – not his phone, his laptop – while I was in the middle of ‘To be or not to fucking be’,” said the actor, who said he thought the offending audience member was sending emails.

“I was pausing and [the stage team] were like, ‘Get on with it’ and I was like, ‘There’s no way.’ I stopped for ages.”
