Brown Barnacles Research Paper
The other species I am focusing on are brown barnacles. Brown barnacles are marine crustaceans and have hexagon shaped shells with an animal living inside it. They are sessile organisms meaning they are fixed in one place on the rocky shore. They are usually found at high tide zones on rocks on rocky shores. According to the data collected from the field trip on the 9th of March 2016, 19% of the brown barnacles of the brown barnacles were found at high tide zones, 6% at mid tide zones and only 1% at low tide zones. Therefore a high majority of brown barnacles live at high tide zones. Brown barnacles usually live at higher tide zones so that they can be further away from their predators such as oyster borers. Brown barnacles are sessile organisms,

They usually consume plankton when filter feeding. Barnacles do this by opening up their plates which they then extend their legs and form them into a basket shape that scoops inwards where their mouthparts scrape the edible particles of the plankton and transfer these particles inside the mouth and consume them as food. This makes the brown barnacle’s legs and mouthparts useful structural adaptations for consuming food. The brown barnacle’s wall plates are also a very useful adaptation as when the tide goes out, it closes its wall plates that have got water stored inside. This makes the brown barnacles avoid dehydration and desiccation. Their wall plates are also very thick and impermeable which reduces water loss and can also protect the brown barnacles from radiation effects. With temperature, brown barnacles are very tolerant towards high temperatures up to 47.5°C but only for short periods of time. The data collected from the rocky shore field trip shows that the surface Temperature range For high tide zone where a large majority of brown barnacles live is 18-27°C with an average temperature of 21°C, mid tide zone with a surface temperature range of 14-21°C and an average temperature of 17°C, and low tide zone with a surface temperature range of 8-17°C and with an average temperature of
