Romania #1881 (1966) – Marbled Rock Crab (Pachygrapsus marmoratus)

The Netted Dog Whelk (Nassa reticulata) is a small marine snail, specifically a species of predatory sea snail in the family Nassariidae. These snails are often found along the coasts of the Atlantic Ocean, from North America to the Caribbean and Gulf of Mexico.

Here are some key characteristics and information about the Netted Dog Whelk:

1. Shell: The shell of the Netted Dog Whelk is elongated, conical, and spiraled. It typically has a net-like or reticulated pattern on its surface, which gives it its name. The shell can vary in color, often ranging from shades of brown to gray.
2. Size: These snails are relatively small, with an average shell length of about 2 to 3 centimeters (less than an inch).
3. Habitat: Netted Dog Whelks are typically found in intertidal zones and shallow subtidal areas, burrowed in sandy or muddy substrates. They are more commonly found in warm, coastal waters.
4. Feeding: As carnivorous predators, these snails primarily feed on other small marine invertebrates like mollusks, crustaceans, and detritus. They use their proboscis to grasp and consume their prey.
5. Reproduction: Netted Dog Whelks are dioecious, which means there are separate male and female individuals. They lay egg capsules that contain numerous small, coiled eggs. These capsules are often attached to submerged substrates and have a gelatinous texture.
6. Behavior: Netted Dog Whelks are often found hidden under the sand or mud, where they wait for their prey. They can be active both during the day and night, depending on various environmental factors.
7. Ecological Importance: These snails play a role in the food web by controlling the populations of the organisms they prey upon. They are also a food source for various predators, such as crabs and some fish.

Please note that the Netted Dog Whelk is just one species among many different types of whelks and marine snails. Their role in marine ecosystems is significant, and they are an interesting component of coastal biodiversity.
