Hello! Can I request spix’s disk wing bat?

(I’ve never done an ask before so sorry if I misunderstood the post)

You did just fine, don't worry.

Spix’s Disk-Winged Bat (Thyroptera tricolor)

I chose a difficult photo reference this time, because these lil dudes look exactly like screaming puffballs with stick-arms from this angle... On the plus side, it’s my first art with more than one bat! Double the bat double the fun double the flavor!

If you have followed this blog for a while, these bats may look suspiciously familiar, especially those round pads on their wrists. But these are not close relatives to the sucker-footed bats in family Myzopodidae- they’re one of five species in a different family, Thyropteridae. And they evolved their sucker-feet completely separately!

The great irony is that, unlike the sucker-footed bats, which use wet adhesion, these bats DO use actual suction to stick to leaves. They have four beautifully round little suction cups on their wrists and ankles, along with reduced thumbs and barely-functional tiny feet. (Feet are unnecessary when you have suction cups.) A ring of cartilage surrounded by muscle allows these bats to contract their suckers to create suction. Like the sucker-footed bats, they prefer to roost head-up, but unlike them, they are able to roost pointing in any direction because they don’t slide around.

The force generated by the bats’ suction cups is so strong that they can support their whole weight hanging by just one.

Disk-winged bats roost in curled up leaves of plants such as Heliconia, and use the furled trumpet shapes of the leaves to amplify their calls to other bats flying nearby. They have to frequently change roosts, as the leaves they sleep in quickly mature and unfurl, so recognizing the individual calls of their family members is crucial and helps them regroup after a night of hunting insects alone.

Spix’s disk-winged bat (Thyroptera tricolor) 

Spix’s disk-winged bat (Thyroptera tricolor), is an insectivorous[2] species of bat in the family Thyropteridae.[3] Although this species is unevenly dispersed, it is widespread and is therefore considered as having a “least concern��� status on the conservation list.[1] The most prominent anatomical feature of this bat, separating it from other bats, is the presence of disks on its thumbs and hind feet. These circular disks act as suction cups, allowing the bats to cling onto and move along smooth surfaces.[3] Unlike most bats, T. tricolor clings head—up from its roost. This phenomenon is observed in six bat species which occur among two families, Thyroptera spp. and Myzopoda spp. The former are known as disk—winged, whereas the latter as sucker—footed. Although the two families represent an occurrence of parallel evolution, the manner in which their unique adhesive anatomy is utilized differs morphologically.[4]These bats cling head—up to the smooth inner, ventral surfaces of the rolled up leaves with openings at the top, of Heliconia, sometimes Calathea, as well as other similar plants, using their adhesive disks.[2] This manner of roosting is said to facilitate rapid escape in the event of a potential disturbance.[5] The bat’s disks take the shape of concave cups, and are supported by an internal cartilaginous plate. An extrinsic muscle, the flexor pollicis brevis, attaches to the plate, such that contraction of the muscle alters overall disc shape,[4]creating suction. In order to maintain the integrity of the disk, T. tricolor is observed to groom the disk, by frequently licking it. In addition to that, the disk contains sweat glands which discharge onto its peripheries, thereby maintaining it in a constantly moist condition.[3]

The suction cups of the Spix Disk-winged Bat (Thyroptera tricolor) allow it to roost inside large, smooth immature leaves. These are one of the few bat species which roost facing head up. via /r/Awwducational https://ift.tt/2Gy66WF https://ift.tt/2GyeOQA

Move over, Spider-man! The Spix Disk-winged Bat (Thyroptera tricolor) can stick to surfaces using its biological suction cups on its thumbs and heels. They live in small groups inside furled leaves which they can use like bugles.

Spix’s Disk-winged Bat (Thyroptera tricolor)

These bats are unique for more than just the suction cups on their wings that they use to roost in rolled up leaves. Unlike most other bat species they roost upside up. That's right, in the photo above, the bats are looking up at you.

Round One - Dad Bat is the best

The Spectral Bat (Vampyrum spectrum) is the most dad of bats and the largest bat species in the Americas. It has soft reddish brown fur and a prominent nose leaf to match its size. This bat species is carnivorous, catching its food with the recurved grooved cat like claws on its thumbs. It roosts either individually or in small colonies of up to five—one such colony was found to consist of an adult male, an adult female, two juveniles (one six month old male and a younger female, both believed to be the offspring of the adults), and a nursing pup. The male spectral bat helps in raising pups, and is often found roosting with his wings wrapped around his mate and their offspring.

The Spix's Disk-Winged Bat (Thyroptera tricolor) is a reddish brown to black bat with a cream colored underside. It is one of six species of bat known to roost head upwards.

bat of the year 2023 final round

Painted Bat (Kerivoula picta) is a distinctive bat of southeast Asia with orange and black markings. Often referred to as the Halloween bat due to its coloration, this bat is believed to use its bright colors as camouflage as it blends in with dried leaves and flowers as it roosts.

Spix's disc winged bat (Thyroptera tricolor) is a native of the Americas, ranging from Mexico to Brazil. It gets its name from the disks on its thumbs and hind feet.

[todaysbat]

bat of the year 2023 round four

Giant Golden-crowned flying fox (Acerodon jubatus) is one of the largest species of bat, with a wingspan of 4.9-5.6 feet (1.5-1.7 m). Also known as the golden-capped fruit bat, this species is native to the Philippines.

Spix's disc winged bat (Thyroptera tricolor) is a native of the Americas, ranging from Mexico to Brazil. It gets its name from the disks on its thumbs and hind feet.

Bat of the Year 2023 Round One

Spix's disc winged bat (Thyroptera tricolor) is a native of the Americas, ranging from Mexico to Brazil. It gets its name from the disks on its thumbs and hind feet.

Spectral bat (Vampyrum spectrum) hails from the Americas as well. It is the largest carnivorous bat in the world, eating birds, rodents and other bats. While it has been recorded eating bats out of researchers' mist nets, spectral bats seem to mainly eat birds. The largest prey item recorded was the white-tipped dove, a bird species close in size to the spectral bat. Because its prey can be so large, it's likely that they only need to catch a bird every two or three days. This bat is one of two species where it is known that the male provides parental care, sleeping with his wings wrapped around his mate and their offspring.
