engleri

Engleri refers to a genus of small, spiny, slug-like mollusks within the family Calyptraeidae. These marine gastropods are commonly known as slipper snails or cup-and-saucer shells. They are characterized by their conical shell, which is often flattened and has a single septum or shelf-like structure inside, resembling a cup or saucer. This internal septum is a distinguishing feature of the Calyptraeidae family.

The genus Engleri is primarily found in the Indo-Pacific region. Members of this genus are typically sedentary as adults, attaching themselves to hard substrates such as rocks, coral, or other shells. They are filter feeders, using their ctenidia (gills) to strain plankton and other organic matter from the water. Their slow-moving or sessile lifestyle makes them vulnerable to predation.

Reproduction in Engleri varies, with some species exhibiting sequential hermaphroditism, meaning they can change sex during their lifetime. This adaptation can be advantageous in populations where finding mates might be challenging due to their sedentary nature. The classification of Engleri within the Calyptraeidae family is based on morphological characteristics, particularly the shell structure. Research continues to refine the understanding of their phylogenetic relationships and ecological roles within marine environments.
