How many animals live in the marine biome? What is the biodiversity of the marine biome? What is a sea star's habitat? What eats kelp in the marine biome? What kind of invertebrate is a starfish? What marine bi
The biodiversity of an ecosystem is a count of how many different species of plants and animals live there as well as a measure of the health of the ecosystem itself. If we find only a few species of plants and animals then the ecosystem is at risk of disruption by a single pest or d...
Similarly, sea otters play a major role in the survival of giant kelp forests along the coasts of California and Alaska. These “marine rainforests” provide a home for a wide range of other species. The kelp itself is the main food of purple and red sea urchins and in turn, the urchins...
Seaweeds are large floatingalgaethat grow in water closer to coastal waters. The long, ribbonlike leaves of seaweeds provide shelter to breeding fish and aquatic animals such as amphibians, sea horses and sea otters. Seaweeds may be red, brown or green, depending on the pigments they contain a...
National Geographic photographer Brian Skerry has been diving in the Gulf of Maine for more than 40 years. After learning these waters were a harbinger of climate change, he set out to document the rapid shift and its ripple effects.
When you think of animals in Australia, you think of koala bears and kangaroos, but you do not think about the species that have migrated there. Most animals in Australia are originally from there and do not live anywhere else in the world. Wombats, can toads, and kangaroos are three grea...
The paper also suggests that self-deception may also have evolved in other animals. There is also no indication that self-deception appeared at the same time as mortality salience. So I don’t think this offers more support for MORT, particularly as Trivers presents no evidence for that ...
For example, the dynamic history of the planetary CO2 and O2 composition of the atmosphere has been largely determined by the biogenic flux of gases coming from respiration and photosynthesis, with levels fluctuating over time and in relation to the ecology and evolution of plants and animals.[...
they pull the eggs of endemic shyshark and catshark species from where they are entwined in the kelp and seaweed left exposed by the tide. many shark eggs are preyed on by marine snails called gastropods. one of the prime culprits in this group of animals is the whelk, a predatory snail...
Orcas are also in decline, plagued by toxic chemicals and plastics. Despite these grim realities, Scales highlights positive developments such as the resurgence of seagrass meadows and kelp forests, which help mitigate climate change. She advocates for sustainable fisheries and warns against the ...
