Lake Loch Ness: Home of the "Loch Ness Monster"
Transcript of Lake Loch Ness: Home of the "Loch Ness Monster"
What does Loch mean?
Loch: It simply means a lake.
Or an arm of the sea, especially when narrow or partially landlocked.
There is a lack of plant life in Lake Loch Ness due to the low nutrients in the water. The upper layer of the lake is mostly clear, but it gets darker as it deepens. Making it harder for sunlight to reach the bottom.

Location: Highland, Scotland
Coordinates: 57.3000° N, 4.4500° W
Biome: Lake Loch Ness is a freshwater lake.
Loch Ness Monster
This particular loch in Scotland is not just well known for its deepest waters, but for its mythical creature named the Loch Ness Monster or Nessie. Nessie is supposedly a plesiosaurs.
The first story of the moster began in 1933, but it wasn't the first time the Loch Ness Monster was heard of. In the 7th Century a man named Abdoman, wrote about a creature that swims around a murky lake. A reason why many believe in the Loch Ness Monster is due to the misty fog that the Lake gives off on a regular basis and the murky waters.
There have been movies and books made all dedicated to the Loch Ness Monster. There has been many sightings, but no true evidence has been found on Nessie.

Let's Begin the Journey
Depth: 788 feet
Inflows: River Foyers,River Enrick, River Oich, Caledonian Canal
Outflows: River Ness

Max Depth: 744.6 feet
Average Depth:433 feet
Lake Loch Ness is just one of the lochs in Scotland. There is a total of 31,460 and the some of the names are Loch Tay, Loch Awe, and Loch Lomond.
Relationships and Speciation
Now For the Best Part
Map of Scotland
It has a moderate sea climate
Fog and rain are usually always present and during the Summer, it is mild and dry.
Since the Lake loch Ness is a fresh water lake, it has a very low salt content (low salinity).
The water is very calm.
Average Temperature is 42 degrees Farenheit
Oligotrophic and Lentic
It is a Lentic Ecosystem because it is a lake and doesn't necessarily flow.
Lake Loch Ness is oligotrophic.
Which means it has an organism that can survive the ecosystem that gives it low nutrients.

Anguilla anguilla: Eels
Pike: Esox lucius
Arctic Char: Salvelinus alpinus

It is a divergent evolution. An examples of this is the arctic char. It is a relative of the arctic salmon and lake trout that lives within Lake Loch Ness.
European eel - “Anguilla anguilla” According to IUCN red list of threatened species, Anguillids are often referred to as ‘freshwater eels’, however, they have adapted and can exhibit inter-habitat migration and that a proportion may stay in estuaries, lagoons and coastal waters, rarely, if ever, entering freshwater. Lake Loch Ness, however, contains more freshwater than England and wales combined. Now, European Eels decline in Lake Loch Ness can be explained as European Eel growth increases with temperature and growth rate is faster in saline water than fresh. Yet, the European Eels migration, which is the longest and most complex of any anguillid species in their life cycle, find their way into the waters of Lake Loch Ness and adapt to conditions of fresh water as they continue the migrations of their life cycle.
- “Salvelinus alpinus” They breed in freshwater and are native to alpine lakes, arctic and subarctic coastal waters. They spend the first few years of their life in freshwater and then migrate to the marine environment spending summers feeding in the sea and winters in freshwater. The Arctic Char shares some similar traits to the Salmon and lake trout, like their large size, shorter head/snout, and their color matches that of the lake whether brown and dark or lighter greenish colors. because the Arctic Char has been a native to Loch Ness since the ice age, they have adapted to the depth and are now mostly brown and orange matching the bottom of the lake.
- “Esox lucius” are large, growing in both length and weight in a linear direction, and also breed and live in freshwater. They are magnificent predators, their aggressive behavior allows them to capture and feed on prey easily and be feared by others as well. Their color is a brown/ greenish yellow, allowing them to blend with the bottom of the lake and have an advantage on prey as they are almost invisible. They can tolerate many temperatures and oxygen levels, allowing them to hunt at the deepest points of the lake.
Arctic Char and Norther Pike Adaptation
Fish in Lake Loch Ness
Most fish have adapted to the lower temperatures and low nutrients in their surroundings since they have been their since the formation of the lake.
Depending on the wind patterns in any given year there can be competition between the Char in the Northern part of the lake and the Char in the southern part of the lake. They display intraspecific competition because if the wind blows all the distributed zooplankton to one location the fish then compete over the location of their food.
There is little known of the biodiversity of Lake Loch Ness. There is still more to learn.
