Texas blind salamander

[6] Its diet varies by what flows into its cave, and includes blind shrimp (Palaemonetes antrorum), snails, and amphipods.

Adults and immature larvae are well-adapted for living in underground streams in caves, and many probably inhabit deep recesses that are not accessible to collectors.

The male then leads the female forward, bends his body into an S-shaped pattern, and deposits a spermatophore on the substrate.

He next leads the female forward with the tail extended laterally until she picks up the spermatophore cap with her cloacal lips.

The spermatophore consists of a crescent-shaped white sperm cap over a clear, gelatinous base that is about four times longer than it is wide.

[1] They are additionally vulnerable to depletion of groundwater resources,[1] which occurs over time when withdrawals for commercial or domestic purposes exceed aquifer recharge through percolation, etc.

[1] A five-year review published in 2021 identified all downlisting criteria as being "partially complete", but warned that current groundwater withdrawal limits do not take into account the likelihood of increasing frequency and intensity of droughts due to climate change.
