Common Atlantic Bubble

Bulla striata

Bulla striata, commonly known as the common Atlantic bubble, is a small marine gastropod that typically reaches a maximum length of 3.4 cm. This species can be identified by its distinctive, rounded shell which is often smooth and glossy. The common Atlantic bubble is found in various habitats, including rocky shores and seagrass beds, primarily within the subtropical regions of the Atlantic Ocean and the Mediterranean Sea. It thrives at depths ranging from 0 to 81 meters, but most occurrences are recorded at shallower depths, with 90% found below 20 meters. As a benthic organism, the common Atlantic bubble is often seen on soft substrates, where it feeds on organic matter. Members of the order Cephalaspidea, to which this species belongs, are mostly simultaneous hermaphrodites, allowing them to reproduce effectively in their environments. The specifics of their breeding behavior are not extensively documented, but they are known to produce eggs. Divers may encounter the common Atlantic bubble while exploring seagrass beds or rocky areas. These snails can be curious and may slowly move about, allowing for close observation. However, they can also be cryptic, blending into their surroundings, which makes spotting them a bit challenging. The conservation status of this species has not been evaluated by the IUCN, and it is recorded as common across various dive sites.
