Mollusk Ecology Mia Yockey And Kimberly Cerili

How the organism was identified • The slug like appearance was a big give away • The Eastern Emerald Eylsia (a photosynthetic sea slug) http: //www. scinews. com/biolo gy/scienceeastern-emerald -elysia-genesalgae-plant 02466. html

Food web v Mollusks are key factors in their ecosystems, being predators and the prey v They have a large diversity when it comes to their diet as well https: //itsgonewrong. com/article/stop-snails-eating-yourplants/

Food web part 2 v Some are grazers, Carnivores, Detritivores and scavengers. v our organisms this week, the Eastern emerald Eylsia is photosynthetic. Making it very unique. v It’s a herbivore cause it eats algae http: //phenomena. nationalgeographic. com/2008/11/18/the-further-adventures-of-the-emerald-greensea-slug/

Carnivorous Mollusk • Squid, Octopus and Cuttlefish are meat eating mollusk. • Eating Fish, crustaceans and even other mollusks. http: //britishseafishing. co. uk/cuttlefish/

Herbivorous and Filter feeding mollusk • Terrestrial Snails and slugs are common Herbivores, eating the leaves of plants. • Clams are filter feeders eating plankton and/or algae https: //www. pinterest. com/cerd 2012/ostrasgigantes-giant-clam/

Scavengers/Detritivores • Terrestrial slugs and Snails are also Detritivores, they eat rotted leaves and other detritus. http: //www. bristolzoo. org. uk/explore-the-zoo/partula-snails

Parasites • Some mollusks are even parasitic, a good example is the unionid clam that attaches itself to the skin and gills of fish. http: //dailyparasite. blogspot. com/2010/08/

Habitat/Niche • This phylum is found all over the place! • To all parts of the Ocean and in Freshwater too for aquatic species. https: //en. wikipedia. org/wiki/Nautilus

Habitat and niche part 2 • Found pretty much everywhere for terrestrial organisms of the Phylum • Most organisms are Marine https: //www. joelsartore. com/ani 041 -00199/

Marine mollusk • The most well known of Marine mollusk is the Octopus and squid and Cuttle fish ( from the class Cephalopod) • Muscles, oyster and clams ( class Bivalve) • As well as the giant sea slug and sea snails ( class Gastropoda) (80% of mollusk are gastropods) http: //www. writeopinions. com/blue-ringed-octopus

Freshwater Mollusk • Majority of freshwater mollusks are clams and Mussels • Some snails as well are fresh water too http: //molluskconservation. org/FWMoll_Ftpag e. html Freshwater Mussel

Terrestrial Mollusk • Examples of terrestrial Mollusks are the snail and the slug. http: //www. arkinspace. com/2012/11/thebanana-slug-natures-giant-recy cler. html

Giant Squids and Sperm whales v Sperm whales are the main predator of the giant squid. v In order to escape being eaten the giant squid uses its ink to confused/startle the whale v A lot of sperm whales have scars on their bodies from when they attacked a giant squid v The giant squid uses its tentacles and beak to defend itself https: //kids. n ationalgeogra phic. com/ani mals/giantsquid/#giantsquidswimming. jpg

Cool Documentary • In this documentary called Nature: The secret lives of sharks and rays. • Around the 18: 55 mark to 20: 40 mark (it’s an hour long documentary) • It talks about mating/egg laying time for a certain squid species and how a lot of species show up to eat the adults after they die • https: //www. youtube. com/watch? v=Mu-HZWHGNac Nature “The Secret life of Sharks and Rays” March 2003. October 2017
