Maitotoxin (MTX) is produced by Gambierdiscus toxicus, a dinoflagellate (single-celled eukaryote) species.

It’s wide left considered the most potent of marine toxins discovered to date, and is one of several implicated in ciguatera poisoning, a rare disorder which occurs due to the ingestion of certain contaminated tropical and subtropical fish.

Symptoms of Maitotoxin poisoning include diarrhoea, vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness and weakness. The onset is usually 30 minutes - 2 days. Along with the ciguatoxin, this causes ciguatera poisoning.

Cannabidiol (CBD) oil is the second most prevalent of the active ingredients of cannabis (marijuana).

CBD oil can be harvested from hemp, a cousin to marijuana. Hemp has a higher concentration of CBD than marijuana, which has a higher concentration of THC.

Unlike Tetrahydrocannabinol (THC), CBD oil does not make you high. Both interact with your body’s endocannabinoid system - they just have different effects.

CBD is psychoactive, just not in the same manner as THC. CBD oil is shown to help with anxiety, depression and seizures.

CBD helps with other conditions such as inflammation, pain, psychosis, IBS, nausea, migraines and many more.

Palytoxin poisoning commonly happens to people who have marine tanks. This poison is present in zoanthid (zoa) corals.

It is not possible to tell which Zoanthid corals contain Palytoxin when deciding whether to keep them in aquariums. Some species of zoanthid have more palytoxin than others.

Palytoxin is the second deadliest poison in the world.

Symptoms can be mistaken for the flu: cough, fever, chills, sore throat.

All worker bees are female. The males are called drones and their only job is to mate with the queen bee. When it’s Winter and the hive has gone into survival mode, the drones are kicked out and are left to die.

A queen’s primary duty is to lay eggs. In order to maintain a large colony a honey bee queen lays on average 1500 eggs per day.

Honeybees have a dance move called the ‘waggle dance’. It’s not actually a dance move at all, rather a clever way of communicating between themselves to tell their nestmates where to go to find the best source of food.

If the queen bee dies, workers will create a new queen by selecting a young larva and feeding it a special food called “royal jelly“. This enables the larva to develop into a fertile queen.

They get worse when it’s cold.

The average age for starting periods has become younger. In the 1800s, it was predicted to be in your late teens (around 17ish). Now the average age for starting your cycle is 12 years old.

They have barely changed since their body structure is very effective for survival.

They’re extremely sensitive to light, having 10 eyes.

Horseshoe crabs are known to gather in large nesting aggregations.

Their blood is extremely sensitive to bacteria, being used to check if there bacteria in vaccines.

They are harvested as bait for the whelk and eel fisheries.

The chair that J.K. Rowling used to write the first two Harry Potter novels recently sold at an auction for £278,000. It had been signed and decorated by the author.

The Harry Potter books were the first children’s books to make the New York Times Bestseller list since E.B. White’s Charlotte’s Web in 1952.

Apparently, somebody in the world starts reading the Harry Potter series every 30 seconds.

These were some of the original character names before Rowling finalised them: Hermione Puckle, Neville Puff, Draco Spinks and Lily Moon (Luna Lovegood).

There were two alternative titles for the final book: Harry Potter and the Elder Wand and Harry Potter and the Peverell Quest.

Edinburg, Scotland provided a lot of inspiration for Rowling as she wrote the HP books due to the gothic architecture.
