Do sea slugs have hearts?
The sea slugs are regrowing vital organs such as the heart, while flatworms and sea squirts don't have hearts to begin with. Oddly enough, the headless bodies can also survive for a few months, their hearts still beating as they begin to rot, reports Christa Leste-Lasserre for New Scientist.

Do slugs have brains?
Aside from its availability in the gardens of Princeton, the slug has a brain and a nervous system that can be kept alive for several days in test tubes. In addition, the neurons, or nerve cells of its brain, range from 200 to 300 microns (millionths of a meter) in diameter, making them visible to the naked eye.
Do sea slugs have brains?
As you can imagine, life is not very complicated for sea slugs. They use their brains mainly to find food, avoid becoming food and to reproduce. While the human brain and nervous system are wired with hundreds of billions of nerve cells, or neurons, sea slugs can get by with tens of thousands.
Do sea slugs have eyes?
Yes, all sea slugs have eyes but they aren't very good at seeing things. We think that all the eyes can do is let the slug know whether it is light or dark, or when a shadow is passing over them. This might be useful if the shadow is made by a fish or something that is coming to eat them.
Are sea slugs toxic?
Cawthron Institute identified the toxin in the sea slugs as tetrodotoxin (TTX), which is also found in other animal species such as tropical pufferfish and the Australian blue-ringed octopus. Tetrodotoxin (TTX) is a neurotoxin. It causes paralysis of the muscles, including the diaphragm, which affects breathing.
Can sea slugs swim?
Like other gastropods, most sea slugs move slowly by waves of contraction that lift part of the surface of the foot, which is lubricated with mucus, but are unencumbered by a heavy shell. Some, such as the 'sea butterflies', swim in the plankton, while others can swim only for short periods.

There are species of this animal living throughout the world. There happen to be 8 species living in the Chesapeake Bay. The level of salinity in the Chesapeake Bay makes this an ideal environment for them. Some of the types living in the bay include: 1 The bushy-backed nudibranch: This animal could easily be mistaken for an underwater plant. It has what appear to be prickly branches sticking out of its back. It can be brown to gray in color and is just 2 inches long. 2 The ridge-backed nudibranch: The ridges all over this animal’s body earned it the name ridge-backed nudibranch. It’s white/yellow in color and lives under rocks and within gatherings of seaweed. 3 The striped nudibranch: This animal measures 3-6 inches in length. It’s brown with a pattern of white stripes. Its rhinophores (scent receptors) look like two small clubs. 4 The frosty-tipped nudibranch: This animal is known by the white tips on the cerata, or horns, on its back. They are yellowish in color and their skin has an opaque appearance.

How do slugs survive?
Slugs' bodies are made up mostly of water and, without a full-sized shell, their soft tissues are prone to desiccation. They must generate protective mucus to survive. Many species are most active just after rain because of the moist ground. In drier conditions, they hide in damp places such as under tree bark, fallen logs, rocks and man-made structures, such as planters, to help retain body moisture. Like all other gastropods, they undergo torsion (a 180° twisting of the internal organs) during development. Internally, slug anatomy clearly shows the effects of this rotation—but externally, the bodies of slugs appear more or less symmetrical, except the pneumostome, which is on one side of the animal, normally the right-hand side.
How do slugs react to predators?
This, combined with the slippery mucus they produce, makes slugs more difficult for predators to grasp. The unpleasant taste of the mucus is also a deterrent. Slugs can also incapacitate predators through the production of a highly sticky and elastic mucus which can trap predators in the secretion. Some species present different response behaviors when attacked, such as the Kerry slug. In contrast to the general behavioral pattern, the Kerry slug retracts its head, lets go of the substrate, rolls up completely, and stays contracted in a ball-like shape. This is a unique feature among all the Arionidae, and among most other slugs. Some slugs can self-amputate ( autotomy) a portion of their tail to help the slug escape from a predator. Some slug species hibernate underground during the winter in temperate climates, but in other species, the adults die in the autumn.
Why are slugs aggressive?
Slugs often resort to aggression, attacking both conspecifics and individuals from other species when competing for resources. This aggressiveness is also influenced by seasonality, because the availability of resources such as shelter and food may be compromised due to climatic conditions. Slugs are prone to attack during the summer, when the availability of resources is reduced. During winter, the aggressive responses are substituted by a gregarious behavior.
How many tentacles do slugs have?
The external anatomy of a slug includes the following: Tentacles Like other pulmonate land gastropods, the majority of land slugs have two pairs of 'feelers' or tentacles on their head. The upper pair is light sensing and has eyespots at the ends, while the lower pair provides the sense of smell.
Why do slugs follow slime trails?
Following a slime trail is also part of the hunting behaviour of some carnivorous slugs. Body mucus provides some protection against predators, as it can make the slug hard to pick up and hold by a bird's beak, for example, or the mucus itself can be distasteful.
How do nematodes kill slugs?
