Barnacle

Food/Predation: Acorn Barnacles are sessile (fixed to one place) as they are permanently fixed to the rocks. This means that Acorn Barnacles cannot move from place to place to hunt for food, hence why they filer-feed. A structural adaptation that the barnacles have that allow them to feed are specially adapted cirri (legs) that filter organic matter from the water. When the tide comes in, a muscle opens the plates at the top of the Acorn Barnacle’s shell. The barnacle then repeatedly waves its

[ 3.1] Which barnacle species ranges into the warmest water? The Chthamalus montagui species ranges into the warmest waters. [4.1] On average, how many high and low tides will a given spot on the coast experience in a day, and why? Along the coast there will be an average 2 high and 2 low tides per day. The reason behind this is many different forces but one of the most important is the moons gravitational pull because of how close it is to earth. The moons gravitational pull along with the

It has a large abdomen associated with being female and seems to be cleaning algae off the eggs she carries. One might believe that this is a female crab simply caring for its offspring but they would be assuming wrong. The crab is actually male, displaying

During the day SpongeBob will either be at The Krusty Krab as the fry cook or being with his friends doing something crazy. There are 7 main characters and only two are girls. The episode “Barnacle Face” season 8 episode 164 which aired in 2011, has only three main characters present. The episode has to do with the drama of Pearl’s high school dance and her face breaking out with barnacle’s (pimples). Pearl is the female whale who does the

producers and inhabit the bottom of the food chain. The next three species are stationary consumers. They are Mussel, Goose Neck Barnacle, and Acorn Barnacle. Because of their consumer status, they are more competitively dominant than algae. The last three components are the mobile consumers: Whelk, Chiton, and Starfish. They

A barnacle contains both male and female sex organs(hermaphrodites). Due to their sessile nature, the barnacles have adapted to maximise the possibilities to fertilise within close packed colonies by the enlargement of the penis (Ratio can be up to 10:1). Once the eggs have been fertilised sexually, these are

Chamapsipho brunnea or Brown Barnacle are a type of barnacle found in the mid-high tides parts of rocky shores. Brown Barnacle are also known as filter feeders so they feed off of algae and plankton. Brown Barnacle are not found in the low tide zones for this reason their shells can close off meaning that they can survive out of water longer by keeping water locked in their shells. Lepsiella Scobina or oyster borer are a predatory sea snail species. they feed off of barnacle and other prey they are found

transect line along this rock and used a 50cm2 quadrat square, to record the percentage of species on the rocky shore at different heights and substrates. From this investigation at the rocky shore we discovered: - Chamaesipho columna (barnacle) - Chamaesipho brunnea (barnacle) - Sypharochiton pelliserpentis (chiton) - Cellana denticulata (limpet) - Cellana radians (limpet) - Cellana omata (limpet) - Austrolittorina antipodum (periwinkle) - Austrolittorina cincta (sea snail) - Actinia tenebrosa (sea anemone)

Biology 2.6 Achievement Standard 91158 Cellana Denticulata, Chamaesipho Columna and Chamaesipho Brunnea are three species living in the intertidal zone of the rocky shore. I am investigating the distribution pattern of these three species and the factors affecting the zonation pattern of these organisms. The aim of the investigation was to analyse and compare the distribution of the separate species, regarding the adaptations and the intraspecific and interspecific interactions- whether being

the 6-plated acorn barnacle is the indicator species. Although no 6-plated barnacle was found but another indicator species was, the rosy 4-plated barnacle was found to be extremely predominant in this zone (refer to kite graph). Despite evidence showing that this is the indicator species we are unsure as to whether or not it is more common in the lower littoral zone, a zone that was not examined. Despite this background information suggests, “In the mid littoral zone barnacles are usually most common”
