Because at the time of Tiktaalik's experience (approximately 375 million years ago) in the Ellesmere Island was experiencing tropical climate.
Arctic fish have a cell membrane structure that contains more unsaturated fatty acids to remain fluid in colder temperatures, while tropical fish have a higher proportion of saturated fatty acids to provide stability in warmer waters. Additionally, arctic fish may have specialized proteins in their membranes to help regulate their internal temperature in extreme cold environments.
Biodiversity generally increases as latitude moves from the arctic region towards the equator due to factors like climate stability, increased solar energy, and longer growing seasons. The equator and tropical regions have the highest biodiversity, while the arctic has the lowest due to harsh environmental conditions and limited species adaptations.
The Arctic Hare is in the Animalia kingdom. This applies to all species of rabbits and hares.
The 8 largest ecosystems in the world are: Tropical Rainforests, Coral Reefs, Tundra, Desert, Taiga, Temperate Forests, Grasslands, and Wetlands. These ecosystems cover various regions and provide critical habitats for a wide range of plant and animal species.
Marine ecosystems, particularly oceans, contribute the most to global net primary productivity. Oceans contain a high diversity of phytoplankton that produce a significant amount of oxygen and sequester carbon dioxide through photosynthesis. This makes marine ecosystems essential in sustaining life and regulating the Earth's climate.
continental drift, which states that continents were once connected in a supercontinent called Pangaea and have since drifted apart. The presence of tropical plant fossils in the Arctic suggests that the island was once located in a different, warmer climate, supporting the idea that continents have moved over time.
You won't find an Arctic wolf in a tropical forest.
From Arctic to tropical.
The theory for fossils of tropical plants found on an island in the Arctic Ocean is that the island was once situated in a tropical or subtropical region, and through the movement of tectonic plates, it shifted to its current location in the Arctic. This suggests that the climate of the island has significantly changed over time due to the shifting of the Earth's landmasses.
Arctic Areas
No..They are tropical and sub tropical species.
Yes most but some are arctic or alpine but most are tropical.
Arctic / Polar country
No, sloths are tropical animals.
temperate
No. Manatees live in tropical and sub tropical regions, not in the Arctic.
It has a warm climate.
