Carotenoids in Marine Animals

Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals p...

Wildlife, Marine, and Zoo Animals

Gas bubbles were found in 15 of 23 gillnet-drowned bycaught harp (Pagophilus groenlandicus), harbor (Phoca vitulina) and gray (Halichoerus grypus) seals, common (Delphinus delphis) and white-sided (Lagenorhyncus acutus) dolphins, and harbor porpoises (Phocaena phocaena) but in only 1 of 41 stranded marine mammals. Cases with minimal scavenging and bloating were chilled as practical and necropsi...

Lipid metabolism in marine animals.

and insulin in birds. Insulin potentiates the glucagon stimulation of lipolysis (Langslow & Hales, 1969), whereas in rat adipose tissue insulin has an antilipolytic effect on glucagon-stimulated lipolysis. In the rat, insulin stimulates lipogenesis in the adipose tissue, whereas avian adipose tissue is either poorly sensitive or insensitive to the lipogenic action of insulin (Kompiang & Gibson,...

Cutaneous injuries from marine animals.

Cutaneous injuries by marine animals have a myriad of clinical presentations. Most require only symptomatic treatment, but some may be limb-threatening or even fatal. This is a report of three cases of marine animal injuries by a stingray, a sea anemone and a jellyfish, respectively, illustrating the potential severity of such injuries. The importance of early diagnosis is emphasised, with a di...
