Bumblebee Snail

Engina mendicaria

Engina mendicaria, commonly known as the Bumblebee Snail, features a shell that ranges in size from 10 mm to 20 mm. Its distinctive appearance includes a white or yellowish background adorned with several transversal black bands, resembling the patterns found on wasps and bees. Compared to other Pacific Engina species, this snail is relatively smooth, with only the initial whorls exhibiting axial costae. The shell is purplish black and decorated with yellow or white transverse bands of varying widths, while the columella is smooth with one to two neat denticles, setting it apart from its relatives. This species inhabits the Red Sea and the Indian Ocean, with occurrences noted off Aldabra, Chagos, Kenya, Madagascar, Mauritius, Mozambique, Tanzania, and throughout the tropical Indo-Pacific, including Papua New Guinea and Australia. Bumblebee Snails are typically found under basalt rocks at high tide levels, thriving in rocky shores and sandy beds. They are primarily nocturnal, allowing them to avoid daytime predators. As carnivores, these snails feed on small invertebrates. Their reproductive strategy involves non-broadcast spawning, and they do not go through a trocophore stage in their life cycle. Encounters with Bumblebee Snails during dives may involve observing them hidden under rocks or moving slowly across the substrate. The species has not been evaluated by the IUCN, indicating a lack of specific conservation status at this time.
