Terms (but no conditions)

Did you happen to see a bolded word that you don't recognize in one of my posts? Well, here I just so happen to have a handy list of terms and definitions.


Apoptosis - programmed cell death, usually for a rogue or compromised cell - a self-destruct switch, if you will.

Autotomy - the ability to detach a body part (lizards dropping their tails is an example of this)

Cerata - Sea slug appendages (see Fun Sea Slugs).

Clade - A group of organisms that all stem from one common ancestor.

Cnidosac - Parts of a sea slug that store nematocysts.

Cultivar - A cultivated variety. Not a unique species or subspecies, but a distinct strain.

Cultivated variety - See cultivar.

Epiphytic - Something that climbs on or leeches off of something else.

Eutherian - A kind of mammal characterized by their highly developed placentas.

Marsupial - A kind of mammal that gives birth to immature young (ex. wombat, kangaroo) which continue to develop in a pouch of some sort, supplied with milk.

Monotypic family - A family (taxonomical classification) that only has one species.

Monotypic genus - A genus that only has one species (the Venus Flytrap, Dionaea muscipula belongs to a monotypic genus).

Monotypic taxon - A taxonomic group that only has one species.

Nematocyst - A stinging cell, such as that of a jellyfish.

Order - The taxonomical classification below class and above family.

Oviparous - Refers to an organism that lays eggs that develop outside of the maternal body. 

Phylogenetic tree - A graph that depicts how closely related organisms are.

Reference genome - A "template" genome assembled with multiple individuals' genomes, meant to be as complete as possible.

Semiaquatic - Refers to an organism that lives in both aquatic and terrestrial environments.

Senescence - natural cell death after a certain number of replications. This helps prevent cancer.

Serotype or Serovar - Cultivar but for bacteria.

Specific epithet - The second part of a standard scientific name, as in, the bit that tells you what species it is. That is why it is called "specific."

Tetrapod - A four-limbed vertebrate belonging to the superclass Tetrapoda.

Ornithorhynchus anatinus

Photo by Michael Jerrard on Unsplash We're continuing the animal trend with a look at the Ornithorhynchus anatinus , or duck-billed platypus. Or just platypus. These guys also have several Aboriginal Australian names, as well as some interesting stories, which I encourage you to check out. There are two  here  to start you off :) Overview - Platypus Basics: What even is a platypus, actually. - Etymology (What's the real  plural form?) - Taxonomy and History - Habitat n' Feeding - Funky Features (But wait, there's more) - Citations Platypus Basics (What even is a platypus?) You've probably heard of the platypus as an egg-laying mammal that seems like an amalgamation of other animals, often including the duck and beaver. Their sizes between regions vary, but males are an average of 50 cm (20 in) with females being slightly smaller. Average adults weigh anywhere from 0.7 to 2.4 kg (1lb 5 oz to 5lb 5 oz) and can reportedly live up to 23 years old ( Fenner et al., 1992 ...

Before you read this, a quick trigger warning. Radiation poisoning can be quite gruesome and it  has a disturbing history, so please take care of yourself and be aware that there will be discussion about signs of radium poisoning. Otherwise, please enjoy!      The thing about radium that makes it so interesting is that it tricks the body into thinking it's something important. Now, the problem is that something is a thing that should be in your body for a very long time - namely, calcium. Exposure to radium in any form is bad enough, but when it sneaks into your digestive system and hides away in your bones...you've got problems. These include commonly known things like cancer, from the radiation attacking unprotected flesh, but can also include brittle or disappearing bones, rotting flesh, wounds that don't heal, and more.      You have heard about radium poisoning from the stories of the girls who painted glowing watch dials in the early 1900s, known...
