This family is part of the larger order Neogastropoda, which includes many predatory sea snails known for their intricate shells and ecological roles in marine ecosystems.

The aperture (the opening of the shell) is typically oval or rounded, with a well-defined siphonal canal, a feature often seen in predatory gastropods that aids in feeding.

As a predator, Maoritomella megalacme helps regulate prey populations, preventing overpopulation of certain species that could disrupt the ecological balance.

Maoritomella megalacme is of interest to malacologists (scientists who study mollusks) and marine biologists due to its unique adaptations and ecological role.

Studying this species can provide insights into the evolution of gastropods, particularly within the Borsoniidae family, and contribute to our understanding of deep-sea ecosystems.

By understanding the ecological roles of predatory gastropods, researchers can better assess the health of marine ecosystems and the impact of environmental changes.

The distribution of Maoritomella megalacme is not extensively documented, but it is believed to be endemic to specific regions of the Southern Hemisphere, particularly around New Zealand.
