Anophthalmus Cave Beetle
A small, blind, depigmented cave beetle found in only a handful of caves in Slovenia. It has elongated legs and antennae for navigating in total darkness and was described in 1937.
Did You Know?
Its unfortunate scientific name, given in 1937, has made it a target for collectors who prize specimens for the name alone, contributing to its rarity.
Crawling Water Beetle
A tiny, oval water beetle with a yellowish body covered in rows of dark punctures. Unlike diving beetles, it crawls slowly among aquatic vegetation rather than swimming actively.
Did You Know?
It stores air beneath enlarged hind coxal plates, which act as a built-in oxygen reservoir while submerged.
