Mitridae

The Mitridae, commonly known as miters or mitra shells, are a family of medium to large predatory sea snails, marine gastropod mollusks in the superfamily Conoidea. There are over 500 recognized species of miters, with new species still being discovered.

Characteristics

Mitra shells are characterized by their distinctive, elongated, cone-shaped shells. They are typically smooth and glossy, with a pointed apex and a wide, open aperture. The shell surface can be adorned with various patterns, including spots, stripes, and spiral ridges. Most miter shells have a distinct "siphon canal" on the outer lip of the aperture, which is used for breathing.

Environment

Miters are found worldwide in tropical and subtropical waters. They typically inhabit shallow, sandy or muddy bottoms, often near coral reefs. Most miter species are carnivorous, feeding on worms, other snails, and small crustaceans.

Feeding

Miters are venomous and use a specialized radula, a ribbon-like structure in their mouth, to paralyze their prey. The radula is covered with sharp, pointed teeth called "radula teeth," which are used to inject venom into their victims. The venom contains a complex mixture of toxins that can quickly paralyze and kill small prey.

Reproduction

Miters are gonochoristic, meaning they have separate sexes. Reproduction typically occurs in the water column, with males releasing sperm and females releasing eggs. Fertilized eggs develop into free-swimming larvae called trochophores and then into veliger larvae, which eventually settle on the seabed and transform into juvenile miters.

Subfamilies

The Mitridae family is divided into several subfamilies, including:

  • Mitrinae
  • Imbricariinae
  • Strigillariinae
  • Costellariinae
  • Cylindrinae
