Habitat & Geographic Range

Compound Sea Squirt

Habitat

Native to Europe and North America and Oceania, inhabiting ecosystems characteristic of the region.

Range

Widely distributed across Europe (8 countries), North America (Canada, Mexico, United States), and Oceania and the Pacific (New Zealand).

gorilla

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 4 distinct biome types within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Cameroon, Congo (Republic), Equatorial Guinea, and Gabon. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

gorilla

The world's largest primate, western gorillas weigh up to 180 kg and inhabit the tropical and subtropical forests of equatorial Africa. Primarily herbivorous, living in family groups led by a silverback male who protects the troop and mediates social conflicts. Critically Endangered, with populations threatened by deforestation, poaching for bushmeat, and outbreaks of Ebola virus disease.
