Do animals communicate? How? Which ones?

Animals may not be able to speak like we do, or write like we do, but they do have other ways of communicating, eg. Wolf howls, frog croaks, dog barking and cats purring.

Animals rely on non-verbal and verbal communication, sometimes they’ll howl, other times they’ll communicate by leaving scent markings behind or how Dolphins splash their tail on the water and how the Peacock spreads its feathers to attract female peacocks.

One study that was conducted showed that Iguanas have well-shaped ears, even though they can’t communicate vocally, it’s so they can hear the warning calls of the paradise flycatcher, the Iguana and flycatcher have nothing in common besides sharing the same habitat and raptors like to snack on them, so when the Iguana hears the flycatcher sounding the alarm, it’ll know to be on the lookout for predators as well.

Meerkats use three different types of communication; non verbal (body language), sounds and scents.
Meerkats purr to show contentment and attachment, they chatter when nervous and squeal when danger is about.
when one “gang” enters another territory the scent part comes into play, Meerkats claim the area they live in by admitting a scent.

Gazelles have a very prominent way of communicating by ‘stotting’, which involves Gazelles jumping into the air with all fours held stiff and backs arched – they tend to do this before running when they see a predator.
Stotting is one of the most common ways a Gazelle communicates to predators.
