Cephalopod

Introduction The most recent research lines are based on understanding wild paralarvae behaviour and prey preferences, refining paralarval nutrition and rearing conditions for O. vulgaris welfare (Iglesias and Fuentes et al., 2014). In the culture of cephalopods, the paralarval life stage is a critical period, especially for octopuses. During this period, the paralarvae must initiate the consumption of a suitable diet to grow, requiring stable conditions for proper development (Iglesias &…

We’ve all heard some variation of a story in which an octopus has escaped its enclosure, gone about its business, and returned to its tank, all without leaving any evidence for the staff or guards. These types of tells are what piqued my interest in cephalopod intelligence and led me to a study conducted by James B. Wood and Roland C. Anderson where the goal was to identify the differences in escape behavior between various types of octopuses. When searching for an answer to such a question, it…

foot. The foot, a modified appendage which offers anchorage and locomotive abilities, is found in all four classes of Molluscs, Cephalopoda, Gastropoda, Polyplacophora, and Bivalvia. The foot of a Cephalopod however, bears little resemblance to the foot of the other three classes. Instead, the Cephalopod foot bears arms and tentacles which offer jet propulsion. [4] To differentiate among the three remaining classes, Polyplacophora have dorsal plates, Bivalvia have a calcium carbonate two valve…

Like a myth coming to life, chameleons have a “superpower” that we wish we had: genetic camouflage. Though tons of animals can do this, the chameleon is the most iconic. They use this ability to heat up, communicate, warn off predators, or to find a mate. Scientists have studied how they do this in order to see if this can aid the human race. This research paper is on the process in which chameleons change their skin tone and how they survive with such a unique ability. Pigment causes skin…

Producers Marine snow- Marine snow is the “rain of food” that slowly falls from the top or middle layers of the ocean zones to the ocean floor. It can also be called detritus. The marine snow is the nutrient that feeds at the bottom of the food pyramid. It’s mostly made up of dead and decomposing animals, dejection, silt and other organic wastes that had been washed into the sea from land. The marine snow got it’s name because it resembles snow with the white fluffy components. As the dead…

WHERE DOES BLACKTIP REEF SHARK LIVE? Blacktip reef shark (Carcharhinus melanopterus) DESCRIPTION The blacktip reef shark not the same as blacktip shark (Carcharhinus limbatus), though they possess similar attributes but also different species of shark. The blacktip reef shark is famous for the black tips on its fin which also makes it to be easily identified, also known as black wing shark. As its name says, blacktip reef shark's pectoral fin tip and dorsal fin are black, while the lower part…

warm-blooded species and prey also differs according to sex or age classes (Casaux, 2009). Juvenile seals normally feed on krill, while older seals consume seals, penguins, and other species (Hiruki, Schwartz, & Boveng, 1999). Generally, prey includes cephalopods, penguins, fish, crustaceans, other seals such as Southern Elephant, Fur, and Crabeater seals, and krill, which has been found to be the primary prey during the winter (Southwell et al., 2012; Hückstädt, 2015). However, the importance…

jellies. I saw a larger diversity of jellies at the Monterey Bay Aquarium, while I saw a larger diversity of bony fishes at the Steinhart Aquarium. I was sad that I did not see many cephalopods and cnidaria in San Francisco, because there was a small amount of jellies in the actual aquarium, but many of the larger cephalopods present were often too well camouflaged to their…

of food. The Emperor Penguin plays an important role in the ecosystem of Antarctica. They are predators to small fish, cephalopods, and crustaceans. Emperor Penguins are important prey to Larger animals like leopard seals and large sharks. There are no cynical influences of Emperor Penguins on humans. Emperor Penguins are carnivores and mostly eat crustaceans, fish, and cephalopods. Proportions of their prey vary seasonally, depending on the amount of prey in the area. Fish prey species include…

described as sensory organs rather than limbs. These creatures can be found on the west coast of North America. The octopuses live in the temperate rain forests, and would prefer to be resting in pooled water than drying out (Vocabulary.com). These cephalopods reach an average size of 30-33 cm. The creatures are in danger of becoming extinct (Zapato). The Tree Octopus is thought to have originated in the roots of Puget Sound, and that is where its reproductive cycle began. They leave their…
