Echinocardium pennatifidum is a species of sea urchin in the family Loveniidae, chiefly found in the northeast Atlantic region. [2] [3]
Echinocardium pennatifidum is up to 7 cm (2.8 in) long. [4] It has coarser, more regularly arranged spines than other Echinocardium. The frontal ambulacrum is flush with the front of the heart-shaped test. It has a short labrum, not reaching the second pair of ambulacral plates. [5] The specific name means "cut into the shape of a feather." [6] This species is critically distinguished from Echinocardium flavescens by its short labrum and the absence of larger spines in the interambulacral areas of the upper side of the test. Up to 7cm in length. [7]
Found in the waters off Great Britain, Ireland, the North Sea and associated islands. [8]
Echinocardium pennatifidum buries itself in coarse sand or fine shell gravel in the sublittoral, from low on shore to depths of 150 m (490 ft). [4]

Gracilechinus acutus is a species of sea urchin in the family Echinidae, commonly known as the white sea urchin. It is an omnivore and feeds on algae and small invertebrates.
Acrocnida is a genus of brittle stars in the family Amphiuridae. The genus contains three members: Acrocnida brachiata, Acrocnida semisquamata, and Acrocnida spatulispina. There has also been observed hybridization between both Acrocnida brachiata and Acrocnida spatulispina. It is a fairly common genus, usually found along the coasts of Northwestern Europe, but with some species like semisquamata appearing around West Africa. Members of this genus primarily prefer intertidal and sub-tidal habitats, and they are they are less likely to be found in intertidal areas by comparison. This genus was not officially classified until 1926, by T. Gislén. One study found that due to the increased calcification that Acrocnida brachiata causes could be a potential source of Carbon Dioxide for not only the warm, shallow environments they live in, but also for the atmosphere.

Echinocyamus pusillus, commonly known as the pea urchin or green urchin, is a species of sand dollar, a sea urchin in the family Fibulariidae, native to the northeastern Atlantic Ocean and the Mediterranean Sea. It buries itself in gravel or coarse sand at depths down to about 1,250 m (4,000 ft).

This species was first described in 1808 by the English naturalist George Montagu who gave it the name Ligula substriata. It was later transferred to the genus Montacuta, making it Montacuta substriata.
