Spider crabs an d algae share a mutualistic relationship. By: Brittany Berrard and Julia Goldman. Example: 1. Bear and fish 2. So there is another example of mutualism or else the there probably would not be any spider crabs and the algae … Mutualism is when two or more different species are in a relationship that involve activities that benefit both of the organisms. This reaction is known as Mutualism. This relationship benefits both of these species because the greenish-brown algae live on the spiders back, which helps the spider crab blend into the shallow areas of the ocean floor where they live. Parasitism is when one organism is affected but the other is not. The algae on their backs serves as the camouflage to hide the crabs from the predators. Mutualism also occurs between spider crabs and algae. This type of symbiotic relationship is also called Commensalism, because the Spider Crab benefits and the Algae is unaffected. Ants and Aphids *Predator-Prey is a symbiotic relationship in which one organism kills another for food. Even though this is a mutualistic relationship, it is a facultative relationship for both meaning it is not obligatory for either organism. A great example of two species that help each other out is the relationship between the Snow Crab and Algae. The algae get a good place to live, and the crab gets camouflage. For our biology class we discovered the interaction between the Stone Crab and Algae in the Gulf of Mexico. In shallow areas of the ocean, the spider crab makes it home, amongst the diverse and dangerous organisms in these warmer waters. Tree frogs and plants *Mutualism is a symbiotic relationship in which both species benefit. Next, parasites can be in forms of ticks, fleas, lice, and leeches. In return, the plant gets a place to live. Ants make fungus from the leaves and their feces. 7. The spider crab lives were many predators live so the algae helps the spider crab camouflage and not make the predators able to see it, and the algae has a place to live. 8- Plants and humans https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2656.12915 The Snow Crab, also known as Chionoecetes meaning snow, tend to live in the cooler more northern oceans. Mutualism: Spider Crab and Algae A type of mutualistic relationship found in nature is between a pair of marine organisms, the spider crab and algae. 5. Spider crabs spend their time in few of the most shallow areas of the sea. Humans and Plants Example: 1. Spider crabs spend much of their lives in areas where the water is shallow, which increases the possibility of being seen by predators. Spider crab and Algae 2. When the fungus grows, the ant eats them in order to live. In return, the algae benefit from a good place to live. 6. Spider crabs live in shallow areas of the ocean floor, and greenish-brown algae lives on the crabs' backs, making the crabs blend in with their environment, and unnoticeable to predators. Ants and Fungus. “ A mutualistic relationship is when two organisms of different species ‘work together,’ each benefiting from the relationship” [2]. Lion and zebra MUTUALISM. Also the spider crab and algae have a mutualism relation. The spider crab and the algae The spider crab berries itself in the algae for camoflage The spider crab benefits and the algae is unaffected symbiotic relationship: Commensalism the barnacle and the crab the barnacle is benefiting by the crabs presence, but thecrab is harmed 7- The crab spider and the algae . Actually, it’s a Spider Crab. It’s called that because of the spider leg-like appendages on either side of its body. Spider crab and Algae. However, on the back of these crabs, there is a certain type of algae that acts as a camouflage for the animal. The Spider Crab buries itself in the algae for camouflage and protection. The algae stays on the spider crabs back, which gives it a place to stay, while the crab gets camouflaged by the algae.
