Physical Description
Stubby rose anemones (Urticina coriacea) have a diameter ranging from 2 to 20 centimeters. They have a muscular column topped with a ring of thick, wrinkled tentacles, often colored in shades of brown, red, or orange.
Habitat and Geographical Range
Stubby rose anemones are commonly found along the Pacific coast of North America, from Alaska to California. In Monterey, they are found partially buried in sandy or gravel bottoms at depths up to 60 feet.
Diet and Reproduction
As carnivorous organisms, stubby rose anemones primarily feed on small fish, crustaceans, and plankton. They capture prey using their tentacles, which are armed with stinging cells called nematocysts. Reproduction typically occurs through external fertilization, where eggs and sperm are released into the water column, resulting in the development of larvae.
Physical Threat to Humans
While stubby rose anemones are not considered dangerous to humans, they possess venomous nematocysts in their tentacles that can cause irritation or allergic reactions if touched. It’s advisable to avoid direct contact with these creatures to prevent any potential discomfort.
