Although whale sharks are massive, they are generally docile and inoffensive to humans. Whale sharks are even sometimes nice enough to let human swimmers hitch a ride.

InsectsStatus/Date Listed as Endangered:
EN-US FWS: December 18, 1997
Area(s) Where Listed As Endangered:
The Comal Springs dryopid beetle was first discovered in 1987 and only recently described as a species in 1992. It is the only known subterranean aquatic member of the beetle family. Its eyes
are non-functional and its skin is thin, translucent, and weakly pigmented. Adults reach only 0.12 inches long, and females are larger than males.
This species can only be found in the flowing and uncontaminated waters of the Comal and San Marcos Springs in Hays County, Texas. Although it is an aquatic insect, it does not swim, and diet probably consists of other aquatic invertebrates. It is believed that its primary habitat zone is permanently dark. Little is known about the reproductive behavior of this species.
This species is threatened due to its limited range, and a decrease in water quantity and quality and pollution due to human activities may threaten its survival. Conservation plans include monitoring of the species and its habitat, and the continued study of its biology and habitat needs.
