commentarium animalium
These animals are tunicates, otherwise known as Sea Squirts. Along with humans, they are in the phylum chordata which makes them closer relatives to vertebrates than other invertebrates such as insects. As larvae, they are free swimming and have what is called a notochord. This notochord was a precursor to the backbone and is found in humans as the discs between our vertebrae. As they reach maturity, they attach onto rocks or other substrate and digest their entire nervous system leaving just their stomachs. They live the rest of their lives as sessile filter feeders. [x]

Kakapos or Owl Parrots are large, flightless parrots endemic to New Zealand. They are surprisingly good climbers and walk many miles for food and to breeding grounds called leks where many males gather and advertise to females. Their mating call consists of a very low frequency boom that carries for many miles. Their population has been reduced to four islands and are considered critically endangered. Major threats are the cats and rats that were introduced by European settlers. [x]

Basically upside down Sea Stars, Feather Stars, also known as Crinoids, are a very interesting class with approximately 625 species known. Generally stationary during the day, they tend to come out at night or extend their arms in order to trap food. Like other Echinoderms, Feather Stars have tube feet, however their tube feet lack the suction cups that are present in Sea Stars, Sea Urchins, etc. They instead secrete mucus that traps food particles and directs it into grooves where cilia move the particles to the mouth.

Pygmy or Silky Anteaters live in the forests of Mexico, Central America, and south to Bolivia. Little is known about the elusive species due to its arboreal and nocturnal behavior. They are solitary animals and like other anteaters, put their paws in front of their face when threatened so they can swipe with their large claws. Although their forests are being destroyed, they are listed as least concern because of their wide range, presumed large population, and tolerance to habitat modification. [x]

Two recently hatched Sunda scops (Otus lempiji). These owls range from 20-25 cm. in height and are one of few species of owls that actually benefit from human activities. [x]

Meerkats, or Suricata suricatta, have more than 20 sounds with which they use to communicate—20 is just the number that has been recorded by researchers. Out of the 6 groups of calls, I personally think that the pup feeding calls are the most interesting. Meerkats know the different calls for each age group of pups and so when a pup cries out to be fed, adult meerkats will search for age appropriate foodand then proceed to bring it back to the hungry pup.
