Marine Mammal Science, Volume 38, Issue 1, Page 58-72, January 2022., 2022 Abstract The Antarctic Peninsula (AP) is rapidly warming and empirical data on abundance trends of marine organisms are required to understand the impact of these physical changes, and interacting anthropogenic impacts, on the ecosystem. Recent estimates inferred increasing abundance of Type A killer whales at the top of this food chain, and here we ...

Persistence of skin marks on killer whales (Orcinus orca) caused by the parasitic sea lamprey (Petromyzon marinus) in Iceland [PDF]
, 2011 Lampreys have long been thought to be a cetacean ectoparasite, due to the observation of round marks on the skin of whales caught during whaling operations.

Cutting blade dentitions in squaliform sharks form by modification of inherited alternate tooth ordering patterns [PDF]
, 2016 The squaliform sharks represent one of the most speciose shark clades. Many adult squaliforms have blade-like teeth, either on both jaws or restricted to the lower jaw, forming a continuous, serrated blade along the jaw margin.

The first sighting of Longman’s beaked whale, Indopacetus pacificus in the southern Bay of Bengal [PDF]
, 2009 Information on at-sea sightings of beaked wholes are rare from the Indian and Sri-Lankan waters because of the relative rarity of vessels working in deep oceans where these species are encountered. A recent survey onboard FORV ‘Sagar Sampada’ brought out

Skin in the game: Epidermal molt as a driver of long‐distance migration in whales
Marine Mammal Science, Volume 36, Issue 2, Page 565-594, April 2020., 2020 Abstract Long‐distance migration in whales has historically been described as an annual, round‐trip movement between high‐latitude, summer feeding grounds, and low‐latitude, winter breeding areas, but there is no consensus about why whales travel to the tropics to breed.

On the measurement of ecological novelty: scale-eating pupfish are separated by 168 my from other scale-eating fishes. [PDF]
, 2013 The colonization of new adaptive zones is widely recognized as one of the hallmarks of adaptive radiation. However, the adoption of novel resources during this process is rarely distinguished from phenotypic change because morphology is a common proxy ...
