PATTERN WEEK

Commemorating a few of the stars from my visits in Budapest Zoo this year.

NAPTIME GIANT RIVER OTTER Pteronura brasiliensis ©Laura Quick Nap Time! Kind of a nice break, as usually these guys are on the move. This is the longest member of the weasel family, Mustelidae, a globally successful group of predators, reaching up to 1.7 metres (5.6 ft). Atypical of mustelids, the giant otter is a social species, with family groups typically supporting three to eight members. The giant otter is diurnal, being active exclusively during daylight hours. It is the noisiest otter species, and distinct vocalizations have been documented that indicate alarm, aggression, and reassurance. The giant otter ranges across north-central South America; it lives mostly in and along the Amazon River and in the Pantanal. #giantotter #otter #pteronurabrasiliensis #southamerica #©lauraquick #losangeleszooandbotanicalgardens #losangeleszoo #lazoo #glaza# #napping #docentclass #vibrissae #carnivore #mammalia #aquaticlife #webbedtoes #furcoverednose #sleeping #amazonbasin #pantanal #endangeredspecies #endangeredanimals #sleepingbeauty #funny https://www.instagram.com/p/B8jo3-FHWPG/?igshid=mqsr0x2kd7ge

THIS GIANT OTTER was described by my boss, Dr. Denise Su! #Repost @fossil_librarian ————————- It’s #WorldOtterDay!!! Do you think otters are totes ardorbs?? Well how about a 110lbs (50kg) otter with a crushing bite? In 2017, researchers published on a new giant otter they named “Siamogale melilutra”. The fossils were discovered in late Miocene (~6 mya) lignite beds of Shuitangba, Yunnan Province, China. This wolf-sized otter is larger than all living otters. The heaviest extant otter is the Sea Otter weighing in at 14-45kg. Researchers also compared the bite force of “S. melilutra” to ten other living otter species and found it had crushing teeth and robust jaws that were 6x sturdier than the extant otters. Possibly acquiring these traits to eat the abundance of big clams at this time. 1) cranium - image from Wang, X., Grohé, C., Su, D. F., White, S. C., Ji, X., Kelley, J., ... & Yang, X. (2018).
