Light and scanning electron microscopic study of the lingual structure in the budgerigar (Melopsittacus undulatus)
BACKGROUND: The tongue, which plays a very important role in food intake by vertebrates, exhibits significant morphological variations that appear to represent adaptation to the current environmental conditions of each respective habitat. OBJECTIVES: The aim of the present investigation was to investigate lingual structure in adult budgerigar. METHODS: Tongues of 12 adult budgerigars were used ...
متن کاملThe Genome of the Northern Sea Otter (Enhydra lutris kenyoni)
The northern sea otter inhabits coastal waters of the northern Pacific Ocean and is the largest member of the Mustelidae family. DNA sequencing methods that utilize microfluidic partitioned and non-partitioned library construction were used to establish the sea otter genome. The final assembly provided 2.426 Gbp of highly contiguous assembled genomic sequences with a scaffold N50 length of over...
متن کاملSarcocystis neurona retinochoroiditis in a sea otter (Enhydra lutris kenyoni).
Sarcocystis neurona is an important cause of fatal disease in sea otters in the USA. Encephalitis is the predominant lesion and parasites are confined to the central nervous system and muscles. Here we report retinochoroiditis in a sea otter (Enhydra lutris kenyoni) found dead on Copalis Beach, WA, USA. Salient lesions were confined to the brain and eye. Multifocal nonsuppurative meningoencepha...
متن کاملSarcocysts of an unidentified species of Sarcocystis in the sea otter (Enhydra lutris).
The number of Sarcocystis species that infect sea otters (Enhydra lutris) is unknown. Sea otter tissues were recently shown to harbor sarcocysts of S. neurona and of unidentified species of Sarcocystis. Whereas sarcocysts of S. neurona have walls 1-3 microm thick with type 9 villar protrusions, ultrastructure of a distinct thin-walled sarcocyst (0.5-0.7 microm thick) lacking villar protrusions,...
متن کاملDiving and foraging energetics of the smallest marine mammal, the sea otter (Enhydra lutris).
As the smallest and one of the most recently evolved marine mammals, sea otters face physiological challenges rarely encountered by larger, more derived aquatic species. To examine the effect of these challenges on foraging costs and resultant daily energy budgets, we measured the energetics of resting, grooming, diving and foraging for adult, male sea otters. The energy expended for these diff...
