Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution
Kylinxia zhangi
- It is an extinct arthropod that lived in the early Cambrian period, about 520 million years ago.
- The fossil of the species was uncovered near the town of Chengjiang in the Yunan Province of southern China.
- Kylinxia is among the 250 or so extremely well-preserved fossil animals described from the region, which are together known as Cambrian Chengjiang biota.
- Features:
- It had a segmented body with a head, thorax, and abdomen.
- Kylinxia sported three eyes on its head, along with a pair of fearsome claws that was possibly used to catch prey.
- It had a fused head shield, a segmented trunk, and jointed legs.
- The creature had a head with six segments, which is similar to modern insects.
Arthropods
- They are invertebrates with jointed legs.
- They make up about 75% of all animals on Earth.
- They can be found in almost every habitat on Earth, from deep-sea hydrothermal vents to the highest mountains.
- Arthropods are divided into four major groups:
- insects;
- myriapods (including centipedes and millipedes);
- arachnids (including spiders, mites and scorpions);
- crustaceans (including slaters, prawns and crabs).
- They are characterised by several key features:
- Exoskeleton: Arthropods have a hard exoskeleton made of chitin, a complex sugar. This exoskeleton serves as both protection and structural support for their bodies.
- Segmented Bodies: They have segmented bodies, which are divided into distinct regions, including the head, thorax, and abdomen in insects. This segmentation allows for flexibility and specialisation of body parts.
- Jointed Appendages: Arthropods have jointed appendages (legs, antennae, claws, etc.) that are attached to their body segments.
- Bilateral Symmetry: They exhibit bilateral symmetry, meaning their bodies are symmetrical on both sides when divided along a central axis.
- Open Circulatory System: Arthropods typically have an open circulatory system in which blood-like fluid called hemolymph circulates in body cavities and directly bathes the internal organs.
CDC issues National Health Alert for infections caused by flesh-eating bacteria
Vibrio vulnificus
- It is a type of bacteria that can cause a fatal infection.
- This infection can happen when a wound comes into contact with raw or undercooked seafood, its juices, or its drippings or salt water.
- It eats away at the skin, muscles, nerves, fat and blood vessels around an infected wound.
- In severe cases, it can lead to septicemia, which is when the bacteria enter the bloodstream.
- It results in a septic shock, where blood pressure drops dangerously.
- Signs and symptoms include:
- Watery diarrhoea is often accompanied by stomach cramping, nausea, vomiting, and fever.
- For bloodstream infection: fever, chills, dangerously low blood pressure, and blistering skin lesions
- For wound infection: Fever, redness, pain, swelling, warmth, discolouration, and discharge (leaking fluids).
- The only method available to avoid getting infected with the bacteria is to avoid coming in contact with it.
- It is advised to make sure any seafood you consume is well-cooked, avoid raw or undercooked oysters and clean your hands after handling any kind of seafood.
