Plural of crawler; animals or machines that move by crawling, or web crawlers that automatically browse the internet.
From Old Norse 'krafla' meaning to claw or scrape. The '-er' suffix denotes an agent (something that does the action). The plural '-s' is the standard English pluralization.
Google's search crawlers read billions of web pages daily, silently indexing the internet. Meanwhile, baby crawlers are among the few humans who move faster on their bellies than their feet!
