Seashells have been used for personal adornment, such as the strings of cowries in the traditional dress of the Kikuyu people of Kenya, [2] and the formal dress of the Pearly Kings and Queens of London. [3] Most molluscs with shells can produce pearls, but only the pearls of bivalves and some gastropods, whose shells are lined with nacre, are ...
Video of Octopus cyanea moving and changing its colour, shape, and texture Octopuses use camouflage when hunting and to avoid predators. To do this, they use specialised skin cells that change the appearance of the skin by adjusting its colour, opacity, or reflectivity.
Anti-predator adaptation in action: the kitefin shark (a–c) and the Atlantic wreckfish (d–f) attempt to prey on hagfishes. First, the predators approach their potential prey. Predators bite or try to swallow the hagfishes, but the hagfishes have already projected jets of slime (arrows) into the predators' mouths.
Arion ater varies from 10–15 cm (3.9–5.9 in), reaching maturity at about 2.5 cm (0.98 in) and moves at a speed of up to 4.5 cm/min (1.8 in/min) [5] The black slug is generally deep black, with some adults being brown or even white. Generally, pigmentation darkens directly with increasing latitude.
The number of eggs varies; it can be as few as just 1 or 2 eggs (Vayssierea felis) or as many as an estimated 25 million (Aplysia fasciata [36]). The eggs contain toxins from sea sponges as a means of deterring predators. [37] After hatching, the infants look almost identical to their adult counterparts, albeit smaller.
A new year means more viral moments of animals being animals. From Florida alligators and Oregon black bears to a Massachusetts great white shark, 2024 proved to be a big year for ferocious animal ...
Peltodoris atromaculata, more commonly known as the dotted sea slug or sea cow, is a species of sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Discodorididae. [1] It dwells in salt water up to the depth of 40m. It is exclusively found in precorralligene and coralligene communities and is very common in such communities. [2]
A 2017 study determined that there were likely five Nautilus species, however these did not exactly correlate to the described species of the genus. [10] While the status of N. macromphalus, N. stenomphalus, and N. pompilius were validated by the genetic study, two undescribed, but genetically distinct, species were discovered in the South ...
