NON Lesson, 1834 (ISSG Database; Minchin, 2008). Common names Tøffelsnegl (DK, NO), Slipper limpet, American slipper limpet, Common slipper snail (UK, USA), Østerspest (NO), Ostronpest (SE), Amerikanische Pantoffelschnecke (DE), La crépidule (FR), Muiltje (NL), Seba (E). Identification Crepidula fornicata usually sit in stacks on a hard substrate, e.g., a shell of other molluscs, boulders or rocky outcroppings. Up to 13 animals have been reported in one stack, but usually 4-6 animals are seen in a stack. Individual shells are up to about 60 mm in length, cap-shaped, distinctly longer than wide. The “spire” is almost invisible, slightly skewed to the right posterior end of the shell. Shell height is highly variable. Inside the body whorl is a characteristic calcareous shell-plate (septum) behind which the visceral mass is protected. -

Because of current social, environmental, economic, and resource constraints, offshore mussel cultivation seems to be a promising strategy. With the objective of optimizing farming strategies that support the sustainability and development of the mussel industry at a microgeographic scale, we evaluated, after a traditional two year production cycle, the commercial performance of spat from several mussel (Mytilus edulis) stocks originating from sites separated by less than 65 km and cultivated at two different grow-out sites (shallow lagoon and offshore waters). -

Snails, Limpets and Chitons: Moving on Edited by Holly Anne Foley and Karen Mattick Marine Science Center, Poulsbo, Washington
TEACHER BACKGROUND Unit 3 - Tides and the Rocky Shore Snails, Limpets and Chitons: Moving On Edited by Holly Anne Foley and Karen Mattick Marine Science Center, Poulsbo, Washington Key Concepts 1. Snails, limpets and chitons each crawl on rocks with a muscular foot to find food and more favorable conditions. 2. These mobile animals also adhere tightly to rocks to survive low tide and to deter predators. Background Some of the most common animals in rocky shore habitats are the snails, limpets and chitons. Unlike barnacles, these animals are mobile. They each have a muscular foot that moves in contractions which appear as waves. The wave movement propels the animal forward a minute step at a time. The wave of contraction push-pulls the animal along. The slime trail snails, limpets and chitons leave has unique chemical properties that alternately act as a glue then as a lubricant depending on the pressure placed on the slime by the animal. The stationary portion is held in place by the glue as the moving portion is easily moved over the lubricated surface. Materials For each student or pair of students: • 1 snail, limpet or chiton • 1 glass jar with a lid • sea water • washable felt marker such as an overhead transparency pen • 30 cm or so string • millimeter ruler • “Snails, Limpets and Chitons: Moving On” student pages Teaching Hints “Snails, Limpets and Chitons: Moving On” gives your students a chance to observe movement in a living marine gastropod or the similar chitons. You can readily obtain periwinkles (Littorina species) or other snails, limpets or chitons from the intertidal zone or from biological supply houses. -

The intelligence of octopuses has long been noted, and to some extent studied. But in recent years, play, and problem-solving skills has both added to and elaborated the list of their remarkable attributes. Personality is hard to define, but one can begin to describe it as a unique pattern of individual behavior that remains consistent over time and in a variety of circumstances. It will be hard to say for sure whether octopuses possess consciousness in some simple form.

NIEA ID Guide Crepidula Fornicata Slipper Limpet
Scan for more Slipper Limpet information Species Description Scientific name: Crepidula fornicata AKA: American Slipper Limpet, Common American slippersnail Native to: North-east US Habitat: Wide range of habitats particularly in wave- protected bays, estuaries or sheltered sides of wave- This species has an oval shell, up to 5 cm in length, with a much reduced spire. The large aperture has a shelf, or septum, extending half its length. The shell is smooth with irregular growth lines and white, cream, yellow or pinkish in colour with streaks or blotches of red or brown. Slipper limpets are commonly found in curved chains of up to 12 animals. Large shells are found at the bottom of the chain, with the shells becoming progressively smaller towards the top. Crepidula fornicata is present in Northern Ireland in Belfast Lough and other coastal sites. Other records exist from around Ireland over the last century however, none of these sites are currently thought to be supporting a population. Crepidula fornicata most likely arrived in Ireland with consignments of mussels. Other possible pathways include; with consignments of oysters, on drifting materials or due to dispersal of larvae. Slipper limpet competes with, and can displace, other filter-feeding invertebrates. The species can be a serious pest of oyster and mussel beds. Slipper limpet is listed under Schedule 9 of The Wildlife (Northern Ireland) Order 1985 and as such, it is an offence to release or allow this species to escape into the wild.

Giant Pacific Octopus
A publication by: NORTHWEST WILDLIFE PRESERVATION SOCIETY Giant Pacific Octopus Enteroctopus dofleini Image from the Monterey Bay Aquarium https://www.montereybayaquarium.org By Veronica Pagowski The octopus is an elusive creature with an alien brain. Like humans, these intelligent animals can open jars, recognize faces, and use tools. Yet, only 35% of octopus neurons are located in their brain while 65% can be found in the tentacles. With such powerful, though strangely organized, cognitive systems octopuses have attracted the attention of numerous scientists and aquarists worldwide. The giant Pacific octopus is no exception. Each year, on Valentine’s day, the Seattle Aquarium draws crowds to view giant Pacific octopus mating--an event that can last over an hour. In British Columbia, this species is common enough that divers frequently report sightings. Characteristics The giant Pacific octopus is the largest of roughly 300 known species of octopus, often weighing over 23 kg (50 lbs) with arm spans up to 6 meters (20 feet). The largest recorded weight for this species was over 90 kg (200 lbs). Typically, giant Pacific octopuses are dark red in color with mottled skin, but these animals can quickly change colour or texture to blend in with surroundings. Though giant Pacific octopus colour changes are not as dramatic as the transformations in some other octopus species, colouring can nonetheless range from dark red to white or yellow while skin texture varies from smooth to rugged, flawlessly matching that of kelp or rocks. Each octopus arm can have over 200 suckers- each with the ability to taste, grip, and lift 14 kg (31 lbs).
