rousettus

It was only described in 2003, the most recently described of the genus, Rousettus.

Other animals, such as the Rousettus fruit bats, produce sounds at a higher frequency, although still within our range of hearing.

Probably, like the fruit bat Rousettus, they just time the silent interval between each click and its echo.

Microbats use echolocation; with the exception of Rousettus and its relatives, megabats do not.

By clicking its tongue, a Rousettus bat can locate objects only 0.5 millimetres across while flying at high speed.

The Geoffroy's Rousette, (Rousettus amplexicaudatus), is a species of megabat or old world fruit bats.

Before the arrival of Europeans, the only mammals in the island were six endemic bat species, included Rousettus, a large fruit bat, consumed by locals.

Linduan Rousette Rousettus linduensis (2003)

The Comoro Rousette (Rousettus obliviosus) is a species of megabat in the Pteropodidae family.

One or two species of fruit bats, however, for instance Rousettus, are capable of finding their way around in total darkness where eyes, however good, must be powerless.

The genus consists of 3 subgenera (Boneia, Rousettus, Stenonycteris), sometimes considered as separate genera:

Leschenault's Rousette (Rousettus leschenaultii) is a species of fruit bat found in South and Southeast Asia.

There are various undeveloped caves which contain a diverse range of cave fauna, including some unique species, such as Liphistiidae spiders and Eonycteris and Rousettus fruit bats.

Egyptian fruit bats, along with other species in the genus Rousettus, are the only megachiropterid bats to use echolocation, which they accomplish by emitting a series of sharp clicks with their tongues.

The second proposes laryngeal echolocation had a single origin in Chiroptera, was subsequently lost in the family Pteropodidae (all megabats), and later evolved as a system of tongue-clicking in the genus Rousettus.

A good proportion of Rousettus's clicks are clearly audible to us (which by definition makes them sound rather than ultrasound: ultrasound is just the same as sound except that it is too high for humans to hear).

Unlike Rousettus, which can see very well and which uses unmodified relatively low-pitched sounds to do a modest amount of echolocation to supplement its good vision, the smaller bats appear to be technically highly advanced echo-machines.

Other local ingredients used in Kanak cuisine include Rousettus (flying foxes) and local deer; marine staples such as lagoon and coral reef fish (including dawa), as well as crabs and lobsters.

Four of these were megachiropterans, Pteropus vampyrus, Rousettus amplexicaudatus, Rousettus sp and Eonycteris spelaea, all of which remain extant species in Borneo and Peninsular Malaysia.

Little Red Flying Foxes (Pteropus scapulatus) came to the park in 2010 in the form of 2 pairs, which live in the foyer of the Tropical House alongside a group of Egyptian Fruit Bats (Rousettus aegyptiacus).

If the sonar device is measuring the distance of targets by measuring the duration of silence between the emission of a sound and its returning echo - the method which Rousettus, indeed, seems to be using - the sounds would seem to have to be very brief, staccato pulses.
