Encyclopedia

Octopus is a soft-bodied, eight-armed mollusc of the order Octopoda. Around 300 species are recognized and the order is grouped within the class Cephalopoda with squids, cuttlefish and nautiloids. Like other cephalopods, the octopus is bilaterally symmetric with two eyes and a beak, with its mouth at the centre point of the arms (which are sometimes mistakenly called “tentacles”). The soft body can rapidly alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight arms behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviorally diverse of all invertebrates. — Wikipedia

    When Kelsi Rutledge came to UCLA to pursue graduate studies, she didn't expect to land a side hustle in Hollywood.

    The zebrafish should be known to many aquarium enthusiasts, mainly because of its striking pigmentation. However, the characteristic black-blue stripes, to which the animal owes its name, only form over time. Its eyelash-sized larvae, on the other hand, are still more or less transparent. Many developmental processes in their bodies can therefore be observed under the light microscope. For this reason, they now serve as a model organism for research groups around the globe.

    Famous for their eight arms, octopuses leverage all of their appendages to move, jet through the water and capture prey. But their movements can look awkward and seemingly unplanned at times, more closely resembling aliens than earthly creatures.
