Myself and @barksbog started this as a conversation after watching A Quiet Place, and how similar horror stories, when trying to make characters scared of making sounds, tend to give the enemy creatures a specific appearance. The 1998 video game Resident Evil was an important hallmark both in the horror genre and in video game conventions; I am not a video game designer myself so I cannot talk about how they built 3D environments etc. but it involved the first stealth mechanic in a game in the form of a blind enemy called a Licker, and a lot of horror ever since have made licker-shaped blind monsters, which is where we came up with the term 'Lickalikes' or 'Licker-alikes'

@gingerjaydraws chose the name Slenderbeasts because these sure are beasts which are slender!

@theload points out that After Man (1981) by Dougal Dixon does also have a predator-that-hunts-by-sight, a speculative evolution of bats that run around on there forelimbs while grasping prey with hindlimbs - these are called Night Stalkers. While these do not match the thin apelike appearance of other examples mentioned, Night Stalkers are linked specifically to the Future Predator from Primeval (2007-2011) which is also a speculative evolution of bats. Most of these monsters are not future bats (often aliens or supernatural creatures), however, but @zenosanalytic also said that these monsters are 'Stalkers', and other commenters also noted a bat connection (see further below).

@iamthekaijuking brings forth the most wonderfully literal 'Blind Angry Chimps', which sums up the main features of these monsters perfectly.

@stat-your-shit-up suggested Scrambler and I personally like the sound of that. They sure do scramble! I myself informally call them scrimby scrumblos sometime, which also has the 'scr' sound so I am team scrambler... @pachelbelsheadcanon also suggested 'Crawlers' but I think these guys move faster than a crawl, definitely a scramble.

I love @gentlygolden's idea Sarcovenators, or 'flesh hunters', the scientific flair of the name adds a kind of clinical classification to the monster, which is very much my vibe (one of my main writing projects is scientifically classifying dragons, see @draconesmundi ) so sarcovenator appeals to me a lot.

Both @klomonx and @draptorronin suggested bat-themed ones, possibly based on the bat examples of these monsters (the Night Stalkers from After Man, Future Predators from Primeval, Vampires from Priest, probably more...) and as these monsters have a gait similar to a vampire bat (quadrupedal and loping) and rely on echolocation rather than sight, I can see a bat connection, so out of 'stupid bats' and 'crimpy bats' I put 'crimpy bats' on the options.

'Cloverlikes' is @junoniadoesart's suggestion, based on the monster from the 2008 horror film Cloverfield - a few other kaiju or giant monsters match this body type, such as the MUTO from the 2014 Godzilla film; however both Clovers and MUTOs are more in the business of smashing buildings than attacking individual people for making too much noise; however the body resemblance is undeniable so I have added it to the options.
