Christmas tree worms
Christmas tree worms as per their names are a species of worm of the class Polychaeta (marine worms) and like many other worms of their family (Serpulidae) they secrete tubes in which they live in. they can be found in most of the worlds tropical oceans from the Caribbean to the Indo-Pacific. they are called Christmas tree worms, due to the multicolored spirals that poke out of the worm’s tube, which are their respiratory organs and they are heavily ciliated causing any prey to get trapped in them and get transported to the worms mouth.
*As per the holiday spirit i will be posting exclusively holiday/arctic animals for most of December (until i run out of animals). starting with the Christmas tree worms for obvious reasons, feel free to request any animals you’d like to see.
The Blue Ringed Octopus has enough venom to kill 26 men and there is no antidote to date. Within minutes of being bitten, the victim will be completely paralyzed and unable to breathe. However, if artificial respiration is applied and continued, the toxins will be neutralized by the body in a few hours.
OCTOPUSES ARE COMING FOR US
Part 1: Mimic Octopus
(pulled from various articles, bolded emphasis always mine, sometimes edited for grammar/relevancy)
In the natural world , mimicking a more dangerous creature is a common strategy for avoiding predators. But there is only one animal that can dynamically mimic many different creatures—the incredible mimic octopus.
Having multiple acts benefits the octopus as predators are less likely to catch on to any individual one. If too many octopuses mimic a single creature—say, a lionfish—then predators are more and more likely to encounter the fake than the real deal.
Like all good performers, the mimic octopus caters to its audience. It only acts like a sea-snake when confronted by territorial damselfish, which are preyed upon by sea-snakes.
Their bodies lack any sort of protective shell or skeleton and they have had to evolve other incredible defenses to compensate. Soft bodies make them vulnerable, but they also make octopuses particularly well-suited to deception.
Without skeletons, they are expert contortionists, and can change shape or squeeze into tight spaces. Their remarkable skin can change texture, becoming spiky or smooth on a whim. It also contains sacs of pigment called chromatophores which can be expanded or contracted to produce rapid changes of colour and pattern. Armed with this arsenal of stealth, all octopuses are masters of disguise. (x)
Mimic octopuses have been observed shifting between impersonations as they cross the ocean floor to return to their burrows. (x)
