The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.
The news agency added that some who have seen crocodiles acting this way think the wild animals are trying to lure people into the water so they can attack them. Crocodile experts are unconvinced ...
Large males can reach as much as 3.5 m (11 ft) in length and weigh more than 215 kg (474 lb). Despite its smaller size, it is a highly aggressive animal (one of the most territorial of all crocodilians), and potentially dangerous to humans. The Cuban crocodile is of interest to biologists for its unique physical and behavioral traits.
Most victims of attacks by saltwater crocodile attacks have been in water but they occasionally occur on land. Saltwater crocodiles sometimes attack boats but do not usually appear to be targeting the occupants. Attacks may occur when a human encroaches on the crocodile's territory. [153]
This was the first verified fatal human attack by a false gharial. [26] However, by 2012, at least two more verified fatal attacks on humans by false gharials had occurred indicating perhaps an increase of human-false gharial conflict possibly correlated to the decline of habitat, habitat quality, and natural prey numbers.
Crocodile numbers in Australia's Northern Territory must be either maintained or reduced and cannot be allowed to outstrip the human population, the territory's leader said after a 12-year-old ...
Phenotypic plasticity refers to some of the changes in an organism's behavior, morphology and physiology in response to a unique environment. [1] [2] Fundamental to the way in which organisms cope with environmental variation, phenotypic plasticity encompasses all types of environmentally induced changes (e.g. morphological, physiological, behavioural, phenological) that may or may not be ...
