Ecological niche

is a Shark a mammal or fish? That is the question that is perhaps most commonly asked when talking about sharks. Since sharks give birth to pups, and a few species lay eggs, the common consensus is that sharks are mammals. Across the board, though, 70% of all sharks give birth, while the remaining 30% lay eggs. Sharks are actually fish, which is sure to be a surprise to many.

WOO AT LAST! Been working on this one for a little while. Orcas are such facinating animals. They are the second most-widely distributed mammal on the planet (after humans), and they fill an ecological niche similar to our own. Not only do they vary.

A new study shows how animal's pupils have evolved to help them survive in their ecological niche as predator or prey.

The shape of animal eyes is influenced by whether it is an ambush hunter or the hunter's prey.

"Long-Fanged Bat"  HYPSUGO DOLICHODON, LAOS & VIETNAM The long-toothed pipistrelle’s impressive canines set it apart from its closest relatives. These extra-large fangs may have evolved to allow Hypsugo dolichodon to prey upon larger or harder-shelled insects than its smaller-toothed relatives.  Over time, the long-toothed pipistrelle would have carved out its own ecological niche, consuming different prey and possibly using different habitat than its closest relatives.

https://flic.kr/p/TtNNFN | Competitive Exclusion | It is well known that different warblers can inhabit the same ecological niche, and sometimes the same tree.  Spend some time in the forest this time of year and even if you never leave one locale, you are likely to encounter more than one species of warbler.  This, however, would seem to be an exception to what is known as the “ecological rule of exclusion.” In essence, any two species which inhabit the same ecological niche should not be…

The White-tailed eagle (Haliaeetus albicilla) — also called the sea eagle, erne (sometimes ern, ørn), and white-tailed sea-eagle — is a large bird of prey in the family Accipitridae which includes other raptors such as hawks, kites, and harriers. It is considered a close cousin of the bald eagle and occupies the same ecological niche, but in Eurasia. This large eagle breeds in northern Europe and northern Asia. The largest population in Europe is found along the coast of Norway. The…

BBC Nature - Adapations website. Adaptations help organisms survive in their ecological niche or habitat; adaptations can be anatomical, behavioural or physiological. Anatomical adaptations are physical features such as an animals shape. Behavioural adaptations can be inherited or learnt and include tool use, language and swarming behaviour. Physiological adaptations include temperature regulation. Go to the website for lots more detail: http://www.bbc.co.uk/nature/adaptations
