Haustrum scobina, or the oyster borer, is a species of predatory sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails. [1] Oyster borers use a mucous layer that surrounds the entrance to their shell to prevent desiccation in the midlittoral and high tidal zones.
Enypniastes is a genus of deep-sea sea cucumber.It is monotypic, being represented by the single species Enypniastes eximia.Due to its unique appearance, the species has been dubbed the headless chicken fish, headless chicken monster, and the Spanish dancer.
The major loss of adult snails resulted in a reduced mean snail size in salt marshes. It was originally projected that it would take about 3–5 years for the L. irrorata population density to recover from the oil spill. [13] However, snail populations still have not made a full recovery nine years after the oil spill.
While animals performing distraction displays are rarely documented as being killed, risks to the displaying animal do exist. [33] One researcher observed and documented an instance in which a second predator became attracted to an animal already performing a distraction display. The displaying animal was killed by the second predator. [33]
As a result, both eyes are then on the side which faces up. The side to which the eyes migrate is dependent on the species type. As an adult, a flounder changes its habits and camouflages itself by lying on the bottom of the ocean floor as protection against predators. [1]
There is a dearth of knowledge about the mesopelagic zone so researchers have begun to develop new technology to explore and sample this area. The Woods Hole Oceanographic Institution (WHOI), NASA , and the Norwegian Institute of Marine Research are all working on projects to gain a better understanding of this zone in the ocean and its ...
As the nautilus matures, it creates new, larger camerae and moves its growing body into the larger space, sealing the vacated chamber with a new septum. The camerae increase in number from around 4 at the moment of hatching to 30 or more in adults. The shell coloration also keeps the animal cryptic in the water. When seen from above, the shell ...
Marine larval ecology is the study of the factors influencing dispersing larvae, which many marine invertebrates and fishes have. Marine animals with a larva typically release many larvae into the water column, where the larvae develop before metamorphosing into adults.
