The Spanish dancer seaslug, Hexabranchus sanguineus, is a fascinating marine creature that lives in tropical waters from Asia to Africa and South America, and has a number of interesting features. It is a large dorid nudibranch, a type of sea slug that is a gastropod, just like common garden snails and slugs, only much bigger.
The Spanish dancer is actually one of the largest of nudibranch species and can grow up to 90 cm (3 ft) in length. However, such an enormous size is quite rare, and they usually measure around 30 cm (1 ft).
