Helen Ma, Condensed Blue Whale

This Project, Condensed Blue Whale, is inspired by the Chinese song Condensed Blue Whale (浓缩蓝鲸) by the artist Qiu De (裘德). It talks about a story that takes place in the year 3000, where a scientist condensed the soul of a gigantic Blue Whale inside the body of an extremely small Euphausiacea, which is a kind of half-transparent shrimp. The small body of shrimp now has the experience of roaming in the deep ocean, but the vast blue whale begins to be skeptical about the question of whether its soul is as tiny as the body it owns at this moment. It is supposed to be a romantic story that questions the philosophical essence of “who I am” – the body, the mind, or the combination of both. However, it is somehow cruel as well. 

Inspired by Sabrina Ratte and her Muse, Donna J. Haraway, I started to consider the idea of the Cyborg (a combination of organism and machine) and the value of the community that everything is mixed in society, without clear binary distinctions. 

When we are observing animals, are animals observing us as well? When society develops to be that high technology and human beings are getting very used to being adapted to living together with those techniques that we are not necessarily able to control, what will be human beings’ future? When we do all kinds of experiments on animals, we might also gradually become some kind of experimental object to some unknowns. Instead of the utopic idea given by Haraway, this project shows my dystopian perspective on the future community.

Krill - The Basics of Life!🧬😉 COMMON NAME: Krill SCIENTIFIC NAME: Euphausiacea TYPE: Invertebrates DIET: Herbivore GROUP NAME: Swarm SIZE: 2.4 inches WEIGHT: 0.035 ounces SIZE RELATIVE TO A PAPER CLIP: View on Pic. The lowly krill averages only about two inches in length, but it represents a giant-sized link in the global food chain. These small, shrimp-like crustaceans are essentially the fuel that runs the engine of the Earth’s marine ecosystems. Role in the Food Chain Krill feed on phytoplankton, microscopic, single-celled plants that drift near the ocean’s surface and live off carbon dioxide and the sun’s rays. They in turn are the main staple in the diets of literally hundreds of different animals, from fish, to birds, to baleen whales. https://www.instagram.com/p/CpYbqI4jGHw/?igshid=NGJjMDIxMWI=

                                                           Species: Euphausia superba

(ITIS, n.d.)

Distribution and habitat

Figure 1. Geographical Distribution of Antarctic krill (fao.org, n,d,)

E. superba inhabits a wide circumpolar belt between the Antarctic Continental Shelf break and the Antarctic Polar Frontal Zone. Antarctic krill live in open marine waters (fao.org, n.d.). The larvae of the krill begin near the seafloor and gradually ascend towards the surface as it develops. Adult krills are found at depths ranging from surface waters to depths of 350 m and have occasionally been found as deep as 600 m. They usually dwell in deeper waters during the winter season (Gierak, n.d.).

Anatomy

Figure 2. External Anatomy of Antarctic Krill

E. superba known as Antarctic krills are shrimp-like in appearance though they can easily be distinguished from shrimp by their visible gills. Just like any other decapods they have exoskeleton which are made of chitin and have three body parts which is the cephalothorax, pleon and the telson. The cephalothorax bears the antennae, compound eye, 6 filter legs which are also called thoracopods and the gills. Krills have compound eyes which aid them in seeing while their antennae serve as another sensory organ as they live in the deep. The thoracopods or the filter legs on the other hand, assists the krill in straining its food from the water. Although the gills, guts and gastric mill are not part of its external anatomy, the three are visible from the outside. The middle part of its body is the pleon where the pleopods and the photophores are located. There are 5 pairs of pleopods or swimming legs that allow them to swim in the water column while the photophores or light organs act as a defense mechanism or a signal for their mates. Lastly, is the telson  which is used by decapods as a paddle in caridoid escape reactions through backward propulsion (Grzimek's Student Animal Life Resource, n.d.).

Life Cycle

Figure 3. Life Cycle of an Antarctic Krills Krills reproduce sexually and it usually happens when food is abundant. The male krill produces sperm packets and uses its first pair of pleopods called petasma to transfer the sperm into the thelycum of the female. They store the sperm until they are ready to lay their eggs. These eggs are fertilized once they are released by the female. These eggs settle at the seafloor and gastrulation happens. Eventually, the eggs will hatch and become a nauplius. In this the nauplius has only one eye and is not segmented yet. Then, the nauplius will molt and become a metanauplius wherein limb development begins and it will start to migrate to the surface which is known as developmental ascent. As it molts and grows, it becomes a calyptopis and eventually a furcilia wherein the movable compound eyes start to project at the edge of its carapace. The furcilia develops into a juvenile which can grow from 4 to 10 mm long (Gierak, 2013).

Ecology

Figure 4.  Thoracic endopodite of krill (wikipedia.org, n.d.)

Antarctic krill are filter-feeders that feed mainly on phytoplankton. They exhibit diurnal vertical migration, which means that they rise to the surface at night to feed by using their small, hair-like legs specifically thoracic endopodites as a suspension feeding basket. Apart from phytoplankton, they also eat copepods, zooplankton, and other krill or molted exoskeletons. In the winter, they eat algae under the surface of sea ice. They are considered the dominant herbivore of the Southern Ocean. Its biomass in the Antarctic Ocean is estimated to be between 125 mmt and 750 mmt, the largest biomass of any species on earth (Hardy, 2008). Antarctic krill is the keystone species of the entire Antarctic food chain. They provide a vital food source for whales, seals, squids, penguins, fishes, albatrosses, and many other species of birds. To avoid predation, they exhibit schooling behavior or swarming. Moreover, krill may be parasitized by organisms like protozoans, particularly the genus Ephelota. This suctorian ciliates interacting with E. superba cause hydrodynamic drag on krill swimming and make the host more vulnerable to visual predators (Gómez-Gutiérrez & Morales-Ávila, 2016). Other parasitic species include Cephaloidophora pacifica and Apostoma sp.

Krill’s POV 

Relationship with humans

Figure 6.  Krill/shrimp chili paste and dipping assortments in Thailand (quora.com, 2016)

Although krill is mainly used as aquaculture feed and bait for fishing, it is also processed into a variety of products for human consumption such as paste, frozen tails, sticks, etc. Krill products have been known to pharmaceutical and industrial industries since it is found that the krill's lipid content can be used as a nutritional source of fatty acids that is potential in lowering cholesterol levels. Studies found that the lipids of Antarctic krill are more stable than those of some fishes consumed by humans. Krill digestive proteases can also be injected into humans to reduce pressure on nerve roots between vertebral discs (Gierak, n.d.). Tou et al. describe Antarctic krill as a “rich source of high-quality protein” with low fat and high levels of Omega-3s and antioxidants and the main source of the renowned krill oil.

5 health benefits of Krill oil you shouldn’t miss!

Little did you know that..

They are age-defying! 

*jaw-dropping moment because olay age-defying serum just cant--*

➔ They have the ability to shrink in size when starve to conserve energy during the winter. Thus, scientists can’t tell the age of a krill solely from its size. 

Phytoplankton is just a summer fling! 

➔ They can survive more than 200 days without food.

Krillions of krills!

➔ Krill swarm together in massive numbers, with as many as 30,000 in one cubic meter of a krill swarm.

A Little Giant! 

➔ It’s estimated that the total weight of Antarctic krill is more than the weight of all humans on Earth (Usoceangov, 2015). 

Food is life but swimming is lifer! 

➔ They are heavier than seawater and must swim constantly to stay afloat.

Climate heroes!

➔ Tarling and Thorpe (2017) have discovered that krill play a crucial role in sequestering carbon.

Advantages vs Disadvantages

Although the cons outweigh the pros in regards to Climate Change, there are still various advantages that directly contribute to Earth.

ADVANTAGES

 The Arctic, Antarctic, Siberia, and other frozen regions of the earth might experience more plant growth and milder climates.

The next ice age could possibly be prevented

The Northwest Passage through the formerly icy Canadian Arctic Archipelago could arguably open up to transportation.

Fewer deaths or injuries would occur due to arctic conditions.

Longer growing seasons could mean increased agricultural production in some areas.

DISADVANTAGES

Changes in ocean circulation and the resulting warmer temperatures disrupt the world’s normal weather patterns, bringing about more extreme weather and an increased frequency of severe and catastrophic storms, such as typhoons and hurricanes.

Higher sea levels lead to flooding of the lowlands. Islands and coastlines are engulfed by water leading to death and disease due to flooding.

The acidification of warming oceans leads to a loss of coral reefs. Coral reefs protect shorelines from heavy waves, storms, and floods and while they only cover about 1 percent of the ocean floor, reefs provide a habitat for 25 percent of ocean species. Demolished reefs lead to increased erosion and coastal property damage and the extinction of species.

Warming ocean waters mean increased melting of glaciers and ice sheets. Smaller ice sheets form each subsequent winter, which has a devastating impact on the habitat of cold-climate animals and the Earth’s reserves of freshwater.

Less sea ice, warmer water, and increased acidity are catastrophic for krill which forms the base of the ocean's food web and feeds whales, seals, fish, and penguins. Emperor penguin colonies are also expected to decline due to the loss of sea ice and rising temperatures.

Word Bank:

Coral reefs- An underwater ecosystem characterized by reef-building corals

Glaciers- a slowly moving mass or river of ice

Ice sheets- a permanent layer of ice covering an extensive tract of land

Krill- any small shrimplike marine crustacean of the order Euphausiacea

EL ATÚN ROJO. ALGUNAS CARACTERÍSTICAS. Libro CIMARRÓN José L. Cort) 1ªpart: El atún rojo,Thunnus thynnus (L.), del Atlántico y Mediterráneo pertenece a la familia de los peces escómbridos (Scombridae).Puede llegar a pesar 725 kg, alcanzar una longitud de 3,3 m y vivir más de treinta años. El registro oficial del mayor atún rojo es de 679 kg, un pez capturado en aguas de Nueva Escocia (Canadá) en 1979, siendo el actual récord Guinness. Forma grandes cardúmenes y se alimenta principalmente de otros peces, cefalópodos, pequeños crustáceos como el krill (Euphausiacea) y cangrejos pelágicos. Su forma es altamente hidrodinámica ya que está totalmente adaptado a la movilidad.Habita en aguas templadas del Atlántico Norte y el mar Mediterráneo (hasta el mar Negro). En la parte oriental del océano Atlántico se encuentra desde Senegal y Cabo Verde (15 N) hasta cerca del Círculo Polar Ártico (75º N), donde se registran temperaturas de 5ºC.En la parte occidental, desde Brasil hasta Terranova. También se ha localizado en el Atlántico sur. Su torrente sanguíneo forma el núcleo de un sistema de intercambio de calor altamente evolucionado, por lo que su temperatura interna puede mantenerse hasta 21°C más alta que la del agua que lo rodea, siendo ésta una de las razones de su amplia distribución en el océano. El atún rojo puede aparecer en las cálidas aguas de las Bahamas a cerca de 30°C y 50 días después en aguas noruegas, donde el agua apenas alcanza los10° C. •••Las migraciones del atún rojo dependen de la edad y la longitud de los peces y están relacionadas principalmente con el desove y la búsqueda de alimento.Las migraciones de peces adultos (>40 kg) hacia las zonas de desove en el Mediterráneo y su regreso al océano para alimentarse se conocen desde hace milenios.Sus migraciones se hacen cada vez mayores a medida que aumentan su tamaño. •••Para realizar la reproducción los atunes rojos emigran formando grandes bancos que eligen las áreas más apropiadas en función de numerosas variables ecológicas y ambientales. En general, las migraciones de este pez, tanto en adultos como juveniles (<40 kg), parecen estar asociadas a los grandes sistemas de corrientes oceánicas.
