Introduction
How can creatures that don’t have eyes, and ears tell if a predator is nearby? We will be looking in depth into the predation of Periwinkles (Littoraria irrorata) and the blue crab (Callinectes sapidus). What are periwinkles? Whats the reaction and relationship between the two species. How can one species detect the other? Once we explore the our creatures we will then conduct an experiment to test if there are any notable difference in the reactions of the periwinkles in the presence of the blue crab.
Periwinkle (Littoraria irrorata)
Periwinkles (Littoraria irrorata) are marine gastropod mollusk that can breathe underwater with its gills and use its shell or “operculum to be able to withstand long periods of time out of …show more content…
The clue crab is typically a bottom-dwelling of estuaries and are also know to live in salt and fresh water bays. The blue crab is equipped with two alike pincher claws that are used for grabbing, crushing, and holding its food and at the same time are used for self-defense against other predatory animals. When females reach their final molting into maturity they will attract males by releasing powerful pheromones in their urine. Unlike the periwinkles the blue crab females come highly fertile and the ability to lay up to 7 million eggs each spawning. This mating season for the blue crab will typically go 11 months of the year ranging from mid-December to early …show more content…
irrorata and C. sapidus live in the same habitat and are linked in the food chain. But as we know crabs do have an ability to see and can move very fast. Periwinkles cannot see and a very slow respectfully. How is it that periwinkles are one of the most abundant creatures in the estuary? Periwinkle and all sea snails have a sense that we don’t have called the Chemoreceptor. The chemoreceptor is transduces a chemical in the water and stimulates a potential reaction based on something in the current environment. Periwinkles can detect the faint amount of pheromones from the blue crab in the water using distance chemoreceptors located on the antennas of L. irrorata. Since the dawn of time there has always been the predator and the prey. But how does that relate to the periwinkle and the blue crab? Well predation is a biological interface where a predator seeks out, stalks, and will eventually feed on its prey whether by itself or as part of a larger group. Predators may or may not kill their prey before feeding, however the predation often results in the death of its prey and the eventual absorption of the prey's tissue through consumption. Once the the periwinkle detects the pheromones of the blue crab the periwinkle will unlatch itself from whatever rock or sea grass it is on in an attempt to flea and hide from the detection of its predator. But this brings to question as to how quickly chemoreception work? Does the periwinkle have to
