Meanings of boto in English

The Amazon River dolphin, or boto, sometimes goes further, penetrating another dolphin's blowhole.

Scientists are still arguing about how many species or subspecies of boto there are.

Rather like bat clicks, the clicks that make up the bulk of boto communications are inaudible to humans.

The truth is that the boto -one of the few remaining freshwater dolphin species on Earth -is still something of an enigma.

As fish eaters, botos sometimes have a challenging relationship with human fishers.

Botos do not exactly go out of their way to make scientific counts easy, either.

Paradoxically, though, some botos go out of their way to make themselves incredibly easy to spot.

But the botos do nothing of the sort.

In parts of the Peruvian and Brazilian Amazon, botos are killed for use as catfish bait.

There, botos play with local children taking a break from helping their family with sales at the market.

It is less clear whether that research can also dispel the myth that botos steal more than just fish.

Some argue for the existence of a southern species in Bolivia, distinct from botos in more northerly Amazonian reaches.

Not all botos are pink.

Researchers observed adult male botos carrying these objects while surrounded by females, and thrashing them on the water surface aggressively.

Although botos are difficult to visually count, there may be another way to work out how many individuals remain in the wild: recording their vocalisations.
