Coastal Ragweed

Coastal ragweed (Ambrosia hispida) is a perennial herb in the family Asteraceae, native to the coastal dunes, sandy beaches, and cays of Cuba, the Bahamas, and the wider Caribbean region. It grows in pioneer beach and dune vegetation, often forming spreading colonies that help stabilise loose coastal sands. Like other members of the genus Ambrosia, it bears inconspicuous greenish-white flowers arranged in racemes; male flower heads produce wind-dispersed pollen that can trigger allergic rhinitis in sensitive individuals. The deeply lobed, hispid leaves are adapted to reflect intense solar radiation and tolerate salt spray. Coastal ragweed plays an ecological role in early dune succession, binding sand and enabling other plant species to establish. The genus is widespread globally, with several Ambrosia species considered noxious weeds in agricultural settings, though Ambrosia hispida is restricted to its native Caribbean coastal range. The IUCN assesses it as Least Concern, reflecting adequate population size across its Caribbean coastal distribution. Pressure from coastal development and tourism infrastructure poses a localised threat to dune communities it inhabits.

Common flying squid

<em>Todarodes pacificus</em> is a cephalopod mollusk in the family Ommastrephidae, order Oegopsida, commonly known as the Japanese flying squid or common flying squid. The species is classified as Least Concern on the IUCN Red List. <em>Todarodes pacificus</em> is native to Asian waters, with documented occurrences including Taiwan, and is widely distributed across the northwestern Pacific Ocean. This species is one of the most commercially important squid species in the world, supporting major fisheries in Japan, China, and South Korea. It typically inhabits open ocean environments from the surface to mesopelagic depths, undertaking extensive diel vertical migrations. The common name refers to the ability of this species to leap from the water and briefly glide through the air, propelled by jets of water and using its fins and outstretched tentacles for lift — a behavior observed in several ommastrephid squids. Populations exhibit distinct migratory patterns linked to oceanographic conditions and spawning cycles. Biological traits of this species remain poorly documented in the scientific literature.
