Source-derived summary

Amphisbaena caeca, commonly known as the Puerto Rican worm lizard or blind worm lizard, is a species of worm lizard endemic to Puerto Rico. These animals are vermicular reptiles that live under logs, rocks, and dirt. Other species of Amphisbaenids in the Caribbean include Amphisbaena bakeri, Amphisbaena fenestrata, Amphisbaena schmidti, Amphisbaena xera, and Cadea blanoides.

Amphisbaenids are legless, worm-like reptiles with elongated bodies nearly uniform in diameter. They are covered with ring-like scales similar in appearance to earthworms. They are underground animals, hence the eyes have degenerated to tiny indistinct spots under the rings.

Description

Amphisbaena caeca is pinkish-brown on the head and tail, with dark spots on each of the scales found throughout its annuli (body rings), of which there are between 214 and 237 in this species. This helps distinguish it from A. bakeri, whose annuli count is greater. It is one of the two largest amphisbaenids on the island (the other being A. bakeri), measuring up to 10 inches (250 millimeters) in snout to vent length (SVL). Like other members of its clade, it has only one median tooth.

Editorial summary

“Amphisbaena caeca” enters the record as species of reptile. Crown Archives preserves that source wording while asking what Amphisbaena, caeca and species can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 182-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Amphisbaena, caeca and species.
Editorial analysis

Why this record matters

“Amphisbaena caeca” is worth following because a concise public description often conceals a longer documentary argument. Here, Amphisbaena, caeca and species provides the most credible route into that argument.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q2844298. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
