Melarhaphe neritoides, common name : the small periwinkle, is a species of small sea snail, a marine gastropod mollusc in the family Littorinidae, the winkles or periwinkles. [1] This species was previously known as Littorina neritoides. Melarhaphe is a monotypic genus, in other words, this is the only species in that genus.
The common periwinkle or winkle (Littorina littorea) is a species of small edible whelk or sea snail, a marine gastropod mollusc that has gills and an operculum, and is classified within the family Littorinidae, the periwinkles. [2] This is a robust intertidal species with a dark and sometimes banded shell.
The eggs have an average diameter of 1 millimetre (0.039 in). The eggs are generally surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Some fish have thick, leathery coats, especially if they must withstand physical force or desiccation. These type of eggs can also be very small and ...
Littoraria angulifera is a herbivore and browses on fungi and algae growing on the mangroves. [3]Littoraria angulifera is ovoviviparous.Fertilized eggs are brooded inside the periwinkle and the veliger larvae are then released and become planktonic.
Littorina saxatilis, common name the rough periwinkle, is a species of small sea snail, a marine gastropod mollusc in the family Littorinidae, the winkles or periwinkles. First identified in the 1700s, it has been misidentified as a new species 112 times.
Adult fish also prey on fish eggs and larvae. For example, haddock were observed satiating themselves with herring eggs back in 1922. [14] Another study found cod in a herring spawning area with 20,000 herring eggs in their stomachs, and concluded that they could prey on half of the total egg production. [17] Fish also cannibalise their own eggs.
Species of this genus package their larvae, known as glochidia, in conglutinates that resemble prey items such as aquatic insects, fish fry, or fish eggs. The lures are intended to attract fish that the glochidia can use as hosts during development. When squeezed, the conglutinate will rupture, allowing the larvae to parasitically attach to the ...
Littoraria irrorata, also known by the common name the marsh periwinkle, is a species of sea snail, a marine gastropod mollusk in the family Littorinidae. [3] The specific epithet irrorata means 'moistened' or 'dewy.' This species occurs in salt marshes on the Atlantic coast and Gulf Coast of North America, from Massachusetts to Texas.
