Gray whale rostrum covered in the endemic Cryptolepas rhachianecti barnacles and cyamids often called whale lice. Whale barnacles typically attach to baleen whales and have a commensal relationship–the barnacle benefits and the whale is neither helped nor harmed. [3] A single humpback whale may carry up to 450 kg (990 lb) of barnacles. [21]
Whale barnacles on a humpback whale. Most barnacles are encrusters, attaching themselves to a hard substrate such as a rock, the shell of a mollusc, or a ship; or to an animal such as a whale (whale barnacles). The most common form, acorn barnacles, are sessile, growing their shells directly onto the substrate, whereas goose barnacles attach ...
Rafting species live either attached to neustonic organisms (e.g. barnacles that settle on Janthina shells) or inanimate debris. Some rafting species have evolved to live on debris at the ocean's surface, such as the smooth gooseneck barnacle Lepas anatifera , while others may be coastal species that settle on near-shore floating debris and are ...
Usually, the only shark that will attack a whale is the cookiecutter shark, which leaves a small, non-fatal bite mark. [100] [101] Many parasites and epibiotics latch onto whales, notably whale lice and whale barnacles. Almost all species of whale lice are specialized towards a certain species of whale, and there can be more than one species ...
Killer whales play an important role in our ocean's ecosystem. Female orcas can live up to 90 years, and male orcas live up to 60 years. Whales can communicate through sounds ranging from clicks ...
Just this month some 200 pilot whales stranded themselves on. There's a tiny tip of sand at the very northern tip of New Zealand's southern island called Farewell Spit. It is lovely and remote.
Aside from humans, just five toothed whale species are known to go through this natural biological process. Menopause ‘may explain why some female whales live decades longer than others’ Skip ...
Xenobalanus globicipitis is a species of pseudo-stalked barnacle. [1] It is usually spotted on the appendages of at least 34 species of cetaceans , commonly baleen whales and bottlenose dolphins . This species is not technically a true stalked barnacle , hence the 'pseudo' in its name.
