Lacrymaria olor – one of the most bizarre animals alive

Lacrymaria olor is a protozoan, typically 100 micrometers (0.10 mm) long, that is found in freshwater ponds. Its name means “swan tear” in Latin, and refers to its general shape: namely, a teardrop-shaped body with a small “head” at the end of a long slender “neck”.

The animal is notable for its ability to extend the neck up to 7 times its body length, and manipulate in many directions — even around obstacles — in order to capture its food.

If you look closely you may see one snatching a meal.
