This is the Giant Triton (Ranella gigantea), a large species of sea snail belonging to the family Ranellidae within the superfamily Tonnoidea. This impressive mollusc is characterised by its robust, glossy shell, which can reach lengths of up to 20 cm or more. The shell typically has a distinctive conical shape and is adorned with intricate patterns, often featuring shades of brown, white, and orange.

Location:
Warm waters of the Caribbean Sea and the western Atlantic Ocean, inhabiting sandy and rocky substrates in shallow marine environments.

Average Size:
Up to 20 cm or more in length.

Family:
Ranellidae (Tritons)

Species:
Ranella gigantea

Ecological Role:
A carnivorous gastropod, the Giant Triton feeds on polychaete worms and other small invertebrates. It plays a role in regulating prey populations within coral reef and seagrass ecosystems, where it is well-camouflaged against its surroundings.

Reproduction:
Giant Tritons reproduce sexually, with internal fertilisation. Females lay egg capsules, and sexual dimorphism may be present, with females often appearing larger—potentially to accommodate egg production.

Conservation Status:
Not currently listed as threatened, but like many marine gastropods, it may be locally impacted by habitat degradation and collection for trade or display.

Collection Date:
This is one of two specimens sharing the same accession number. This example is a male, which appears smaller than its female counterpart; the larger size of the female may be to accommodate the presence of eggs.
