Compound Sea Squirt

<em>Didemnum vexillum</em>, the compound sea squirt, is a colonial tunicate in the family Didemnidae native to the northwestern Pacific Ocean, widely recognised as one of the most ecologically disruptive marine invasive species globally. It has been introduced through shipping and aquaculture to the coasts of Europe, North America, New Zealand, and other regions, where it forms extensive, rapidly-spreading mats that can smother native benthic communities including rocky reef habitats, shellfish beds, seagrass meadows, and aquaculture equipment. Each colony consists of numerous individual zooids embedded in a tough, gelatinous or leathery tunic that is often cream, pale yellow, or orange in colour. The compound sea squirt is a filter feeder, drawing water through siphons to extract phytoplankton and suspended organic particles. Colonies can fragment and regenerate from small pieces, facilitating rapid spread via anchor chains, boat hulls, and aquaculture gear. The IUCN lists it as Not Evaluated on the global Red List, a reflection of its invasive abundance rather than conservation concern. In its introduced range, <em>Didemnum vexillum</em> is associated with declines in native invertebrate biodiversity and economic losses to shellfish aquaculture. Biological traits including colony growth rates and lifespan vary by environmental conditions; detailed population biology remains an active research area in invasion biology.

giraffe

The tallest living animal on Earth, giraffes can reach 5.5 meters in height and weigh up to 1,750 kg. Their elongated necks — containing the same seven cervical vertebrae as all mammals — evolved for feeding on acacia trees in African savannas and woodlands. Social animals living in loose herds with no permanent bonds, giraffes communicate through infrasound and body language. Vulnerable, with populations declining due to habitat loss and poaching.
